Updated Ride Height & Alignment Suggestions

Our Street Ride Height recommendation has been update to reflect our new thinking for improved clearance on some of our ever deteriorating road conditions.  We raised our recommendation by 5mm.

A proper alignment is critical to the performance of your lightweight sports cars.  These cars are very sensitive and respond well to changes in the suspension setup.  These recommendations are based on experience we've gathered since 2004 with the Lotus 111 platform.  Your results may vary so we suggest you start here and tweak as your driving style demands.  

Make sure that your car's suspension components are in mechanically sound condition.  Check your ball joints, toe links, track ends, etc to ensure that nothing is worn out.  See our 60pt Prep Sheet for a great reference.  Consider our Suspension Refresh Kit if you discover worn-out parts have a higher mileage car.

Recommended settings for an Elise/Exige street/track car with R-compound tires.         

                          Front                 Rear
Ride height    130 +/- 3mm    135 +/- 3mm
Camber          -2.2° to -2.5°    -2.4° to -2.7°

Toe (total)       0                       3mm total toe-in

Recommended settings for a track Elise/Exige car with slick tires.

                           Front                      Rear
Ride height    120 +/- 3mm              125 +/- 3mm
Camber            -3°                             -3°
Toe (total)       0 - 1mm toe out        3mm total toe-in

--------------------------------------------------------------------------------------------
Follow These Steps:

1.      Set the ride height.  

2.      Set camber.

3.      Set toe.

  • To set the camber, remove all your stock shims as well as the ABS shim. You may need to install FASTarms or machine your stock steering arms to obtain optimal camber.  Remember to use thread locker on the steering arm bolts.
  • While a lower ride height is possible, we find the suspension works best at these recommended heights and the chance of scraping the bottom of your car is less.
  • Write Down All of Your Changes!  Write down your alignment settings and then note how the car performs. Write down any changes you make and record the results. This is the best way to get the car dialed in exactly how you like it.  Use our Alignment/Set-up Sheet to help keep tabs on the changes.

Evora GT Tuning: Power & Compliance

 We have been working on a '20 Evora GT to increase power but also improve handling for this client.  He wanted better front end grip and more compliance for the rough tracks that he frequents.  We received the car and started our upgrades and tuning.

Power

We installed parts from Komo-tec along with sending out the SC for a port and polish.  A slightly smaller pulley was also installed along with a Cold Air Intake, Headers, Sport Cat. and Sport muffler.  Brent came down to tune the car once we had the upgrades installed.  We were able to get the car up to 450rwhp on a local dyno, which translates to about 500hp at the crank!  We believe this is the only 500hp Evora in the US running a stock ECU.


Handling

The owner of this car has a fair amount of experience driving race cars.  He loves this car but felt the front end was not gripping the way he wanted.  He also wanted more compliance to absorb bumps and rough sections.  We sourced a set of Nitron Triples and he secured new upper wishbones to be able to add more negative camber.

Nitron stopped by to see the install and we were able to optimize the routing of the hose and reservoirs. We used our V2mounts to make securing the reservoirs even better.  Dialing in the ride height went well with the client requesting 5mm more rake than stock.  The car's ride height was dropped more than stock.  We were able to add much more negative camber as well thanks to the wishbones.

Supercar Performance

She drives great with excellent compliance.  The turn in is excellent and grip superb.  The power is also very good.  This combo on an Evora 400/GTs is pretty impressive.  I think it is a perfect supercar combination!  These Evoras may be the hidden trackday gem that many people don't realize exists!
