Optimum Ride Height for NA6

[Garry]

Looks bodge but yeap, the circlips are holding up the car. The Koni's use the same system.

For the front ride height I would try either getting a spacer made up to fit on top of the circlip and under the bottom spring seat or getting another groove machined into the shock body a bit higher up. Either of these methods are prefered to adding a spacer between the top of the shock and the body. By raising the spring seat you will regain some of the lost suspension travel and increase ground clearance. Adding a spacer on top of the shock will only increase your ground clearance.

One thing to remember though, due to the ratios on the lower control arms you'll only need roughly 15mm change in height at the shock to get around 20mm at the guard.
