1) Know the goal and the limits. When setting ride height, you are not really just setting ground clearance, you are setting where the suspension sits in its travel. Ride height is just a more simple way to do this than measuring an exposed shock shaft or the angle of the a-arm. The Lotus engineers spec'd the stock ride height not only to provide adequate ground clearance, but also to put the suspension in the ideal spot in the travel. If you want to set ride height much below about 120mm, it is best to do this with raceUPRIGHTS these allow a low ride height (and CG) but leave the suspension geometry closer to stock. We do not recommend these for the street.
2) Settle the suspension. When you jack up the car and the suspension droops, the tires actually move inward toward the center of the car. When you lower the car back down, the tires stick to the ground and do not push outwards, this causes the car to sit artificially high. We use hubstands with built in rollers to stop this but you can settle the car back down by bouncing and rolling it back and forth a few feet. It is important that you do this the same way each time, I prefer to push the car down and allow it to rebound on its own (we also set the rebound and compression damping to full soft).
3) Care for the threads. It is critical that the threads on the shocks are clean before you make any adjustments, dirt and grit not only make adjustment difficult, it can damage the the threads. If your suspension setup demands that you preload the spring to achieve the desired ride height, it can become very difficult to turn the spring collar. Resist the urge to grease the threads as this will attract dirt and nastyness. We have been experimenting (with good results) with using a dry graphite lube. This provides plenty of lubrication to the threads without making a mess.
|We use a lube like this, it also comes in smaller bottles and spray cans.|
4) Tender springs. Certain spring rates and lengths make the use of tender springs necessary. Sometimes when trying to achieve a low ride height, the spring collar is backed off so far that when the suspension is in full droop, the spring becomes loose. Adding a tender spring to the mix will keep the main spring in place and prevent it from making noise or damaging the shock. If you need some tender springs, just give us a call and we can get you setup.
