Track Surface Differences - Choosing the Right Suspension

I am amazed at how smooth the tracks (and roads) are in England. My last track day at Bedford Autodrome along with a previous visit to Brands Hatch and Donnington confirmed that conditions are much better than what we experience at many tracks and roads here in the US. I have also been to Fuji and driven on Twin Ring Motegi in Japan so know that they also enjoy smoother conditions.

Why is this important? Suspension set up. With the bumpy conditions found on various tracks and roads we run, a compliant suspension is key. Too high a spring rate will create a car that does not soak up the irregularities. Good rebound and compression adjustment becomes key as well.

To that end, we have kicked off three new spring rate packages that you can select when ordering your Nitrons. Our experience has also shown that aero plays a significant role in spring choice. Early this year, while testing Nitrons with 525/650lb springs - it became apparent that the high downforce ReVerie kit on our Exige could use some more spring. We installed 550/700 and the car ran like a dream - it sucked up the bumps and ran the curbs like never before. Nothing seemed to upset it, even on our bumpy tracks (Willow & Buttonwillow in this case).

Rebuilding shocks last week at Nitron showed me the amount of options that exist in tailoring a suspension system INSIDE the shock! Choosing the correct valving to match your spring rates is a critical part of a sorted kit. Working with Ralph@V2, some select Lotus Challenge racers and of course, Nitron UK, we will be working to refine our kits to meet our US needs. And since Nitrons can be rebuilt/revalved by us, we will be able to tweak your kits to meet your specific needs.

Nitron Testing at the Bedford Autodrome Track

Ralph from V2 and I were in England last week getting training at Nitron. Guy Evans, Nitron MD, was our gracious host who along with his staff, provided us the needed training to start up our Nitron North America program. This team answered our unending questions on the rebuild, revalve and upgrading of Nitrons. After an intense week of info overload, we had the chance to do some testing at the Bedford Autodrome. This former airbase is now a great facility that can be rented for testing or for training. They offer an excellent program that gets you into several awesome cars and onto the track. We ran the 3.8 mile track config. Learn more about Bedford: HERE

We brought Nitron's newly rebuilt 111R (Elise). They bought this crash damaged car and have begun making it into their newest test vehicle - the N2. It featured a roll cage, CF seats, Nitron Single Adjustable suspension, Nitron toe links, Nitron brakes and a brand new R888s on TD cast wheels.

This was the first shakedown trip for the car so we drove carefully at first (of course the rain helped). But quickly we found the car was well sorted and a fun track day companion. This picture is of Ralph working his smooth style to the max...

Driving on a new track while shifting with my left hand added to the challenge. I also had to use quite a few towels to better fit my short self into the fixed seats that were positioned for 6ft+ Guy. After my first stint in the rain, I got the chance to get settled. The second stint came after lunch with a drying track. More fun and more speed. I started getting the line down and started linking several of the corners like a track regular and began passing quite a few of the other cars. I was not 100% with my left handed shifts but that will come with more practice. Luckily, I don't have this issue in the US. 8^)

Atom Rear Wing Strut is Finally Done

Steve came by the shop with the finished rear strut assembly. A few tweaks were made and the wing bolted on. We set the slot gap to 10mm. Additional wing adjustment was available for the main wing on the strut. We set this fairly conservatively. We had installed the front TMI wing a month ago. The car has the look of the current gen F1 cars with a large front spoiler and narrower rear wing. The dual element wing from ReVerie looks fantastic. It is an excellent design and should prove to be very efficient.

The struts are a work of art with a trailing edge that is almost too sharp. Steve built them on his own mill and will build them to order for us. Final production versions will have a tumbled and

anodized finish. Since these will be custom ordered, we can anodized them to colors chosen by the client.

We took a quick trip with the car around our test route. It had already gotten dark but we had to drive it! The added downforce was clearly evident on a fast bend on the route. Now we need to get this car to the track to dial in the suspension.

I spent some time driving it on Saturday. We were dialing in our new 7100rpm tune with Steve from Secant and the car ran well. The added downforce adds a high level of comfort as the Atom felt fully planted.

Nitron Uprights and More

Guy and his engineers have been busy developing some new products that stretch beyond his normal line. He has developed a line of race focused products that complement Nitron suspensions. New front uprights and rear uprights have been built with several key features. These will also take new brakes that have been developed for race use. New toe links with a novel new design have also been sorted. See the Nitron website for more detail on these items: Click Here

Nitron, Sector111 and Simply Sportscars have embarked on a global Technical Partnership that will strive to develop even more serious products for the Elise/Exige variants. Our goal is to sort out products that will be track and race focused with ultimate performance. Expect us to embrace the Lotus mantra of performance through lightweight so that we can extract every possible ounce of performance.

We have also made an investment in service for Nitron suspensions in the North America. A shock dyno has been ordered and will allow us to rebuild and revalve Nitrons to spec. Ralph at V2 Motorpsorts will be our partner in providing the service that will be required for anyone running these race shocks. Expect an even more comprehensive and customizable Nitron offering from us - with complete service.

Stay tuned for more detailed information.

ReVerie CF Exige Hatch Update

Simon@ReVerie just sent me this pic of the near complete carbon fiber hatch. They are very light at 5.5lbs. He still needs to fit the rear slats in the intercooler portion of the lid. 1/4 turn fasteners will be included. Pulling weight from the top of the Exige is something that is not only noticeable - but fully benefitial. Of course they are built to the typical ReVerie quality: prepreg and autoclaved. Properly light and stiff.

We will have them priced at $2500 and expect to get them by the end of Oct.

ULTRAlightweight - ULTRAdiscs

ULTRAdiscs have proven themselves on and off the track since 2005. A key reason for the success of the ULTRAdiscs is the gain in performance they bring, especially through weight reduction.

These ULTRAlightweight two-piece, floating rotors will save you 10 lbs of unsprung weight (weight not supported by the suspension, i.e. wheels, tires and brakes) by using strong and light materials and an innovative design.

ULTRAdisc’s two-piece design allows the hats to be made from strong and lightweight anodized aircraft 6061 T-6 billet aluminum. The floating rotors themselves are made with a high-carbon iron that is perfectly balanced for strength and lightweight.

More weight was taken off by designing each ULTRAdisc to be corner specific - we can claim to be the very first to develop this innovation for the Elise/Exige. As many of you know, Lotus uses one part number for all four brakes. The front and rear brakes are the same rotor even though the brake pads are of different size. The ULTRAdisc rotors are tailored to match the swept area of the smaller calipers in the rear and the larger calipers in the front. This correction eliminates 3/8” of heavy unused rotor surface per rear wheel. This alone saves 6 pounds of rear unsprung weight!

Adding power will make your faster in a straight line but reducing weight, specifically unsprung weight, enhances nearly every performance characteristic. By sticking to Colin Chapman’s philosophy of “simplify and add lightness,” you can improve acceleration, braking and cornering grip at the same time.

ULTRAdiscs will not only give you greater stopping power, but the loss of unsprung weight will give you more precise steering inputs and better turn-in characteristics.

All of this weight savings and durability has made ULTRAdiscs a favorite of the fastest Lotus Challenge Series drivers. Brent B.'s high-power, high-aero, race-winning Exige to our low-power, no-aero Project Nirvana Elise run ULTRAdiscs with excellent results. Reducing unsprung weight will improve your Lotus's performance no matter how it's setup.

Sector111 Podcast- Martin from Girodisc

We spoke with Martin, Principal at Girodisc, about our ULTRAdiscs and all sorts of other brake-related issues in the newest Sector111 Podcast. Martin talks about how and why he started Girodisc, the history of cross-drilled brakes and why manufacturers still offer them & what makes ULTRAdiscs so good!

ULTRAproven - ULTRAdiscs

We developed ULTRAdiscs with Girodisc over four years ago. Since then, ULTRAdiscs have proven themselves in almost every manner possible. We combined Martin @ Girodisc’s years of automotive engineering experience (5 years of which were spent at Porsche Engineering Services) and our knowledge of the Lotus Elise/Exige to develop the perfect OE replacement brake solution, the ULTRAdiscs.

ULTRAdiscs have proven their performance and longevity on the street and race track since 2005. It’s the rotor of choice for the fastest Lotus Challenge Series competitors. ULTRAdiscs have been run on the track with fantastic results on cars with high power and massive downforce as well as on N/A cars with no aero. ULTRAdiscs have been proven time and again to deliver regardless of car setup or track.

The race track is a great place to test the performance of products. The extremes of track use are hardly ever duplicated on the street. However, actual street miles are just as hard to duplicate. ULTRAdiscs have spent just as much time proving themselves on the street as they have on the track. The Sector111 Spyder took a set of ULTRAdiscs over to 30,000 miles and still had life left in them! No other rotor on the market can say that.

ULTRAdiscs are the only aftermarket rotors to have been proven on the road and track for as long as they have. They were developed back in 2005 to be lightweight and longlasting. After being put to the test for over four years, we have proof these rotors will deliver!

When it was time to upgrade the brakes on our Project Nirvana, there was only one rotor up to the task: the ULTRAlightweight, ULTRAlonglasting and ULTRAproven ULTRAdiscs.

raceVIEW Install Tips

We just installed raceVIEW mirrors on Project Nirvana last Friday. These carbon fiber side view mirrors actually save 2lbs of weight plus reduce visual 'weight' as well. The car looks far sleeker now with this addition. Improved forward vision is another bonus as the clunky stock mirror stalks are eliminated opening up your view as your strake those apexes. It's been awhile since we installed raceVIEWs so we refreshed our memories and found some new install tips to share with you.


1. Masking tape is your friend.

• We used it to hold the new bolts to our allen wrenches during install
  
• Cover painted areas that you are working on to minimize scratches
  

2. Use the 2 wrench method to install base plate

• Rick came up with the idea of using 2 wrenches to hold the bolts in place while lining up the base plate plate. This works like a charm to line up to the threaded sections of the base plate

3. The angle of the bottom bolt is extreme

• This bolt is hard to see when peering through the hole but this picture gives you an idea of how the wrench must be angled


• We did not install the new bolts in this location on our last Exige as it was blocked by metal plate. The raceVIEWs never loosened up on the Exige even after 3.5yrs of use. We left them off of our Project Elise as well to see if it will stand up. We did use some serviceable threadlocker on the bolts. We expect it will be fine as our kit is much lighter than the stock mirrors so 2 bolts should be fine....are we channeling our inner Colin Chapman? ;^)

Sector111 Baffled Oil Pan

As many of you know, engine oil starvation is a real problem for track driven Lotus Elise/Exige. In high 'g' turns, the oil can stand vertically in the stock oil pan starving the pick up and as a result, the rest of the engine. We have been working with a local oil pan specialist to develop a high quality baffled pan that will put the issue to rest.

Project Nirvana has been on our lift for some time to dial in our pan. After several tests, we finally have the first article on the car and onto the road. Oil isolation is a key objective with the pan. We spent significant time insuring the size of the oil isolation area and pick up location. The first picture shows the engine without the stock oil pan. You can see the stock pick up in this shot.

The second picture shows us test fitting a 'skeleton' of the pan to confirm clearance and dimensional fit. This shot gives you a peak inside at the trap door openings that help contain oil close to the pick up. Essentially you create a cavity within the pan that isolates the oil even in high 'g' situations.

Though our pan has more oil capacity than stock, this was of lesser concern as stock cars have plenty of capacity thanks to remote oil coolers. Based on our experience quality of the fabrication and features became a higher priority of us. We want a solution that fixes oil starvation first, is fabricated to a high standard and fits correctly without additional machining. You can see that the welds are beautiful and can be found inside and out with our solution. Additionally we use high quality/performance drain plugs with 0-rings. Our pan mated to the engine beautifully.

We identified a few additional changes that will be incorporated into the final pan. We are now testing ours and will plan to release it as soon as we are complete.

I've been driving Nirvana for a few days and so far no leaks....
