What do people recommend for ride height and alignment settings for a 2.0L being used primarily for autocross. The rear ride height is constrained by the springs with the perch on the lowest "slot" in the Koni shock. For front height I was thinking of 125mm from the center of the torsion bar to the center of the spindle. This is 35mm lower than the stock 90mm. For camber I was thinking of -2 degrees in front and -2.5 degrees in back.

I've finally got the suspension put back together with 180# springs and Koni Sports in the back, 21mm torsion bars, Koni Sports, poly bushings, and turbo tie rods in front. Now I just need to set the alignment and get a decent set of tires (Faken 615s) on it.

I respectfully disagree.

Measure from the top of the rim to the bottom of the fender lip both front and rear.

Set the front of the car 1/4 inch higher than the rear.

When you hit the brakes hard during an autocross, you do not want to lift the rear end of the car... a slight rearward rake will help with rear end traction during aggresive braking and dramatic weight transfer...

in addition, when you stomp on the gas, after braking, you reset the car, and transfer the weight again to the rear.

I had my car set with a slight forward rake, like a muscle car...and during heavy braking I was experiencing the rear letting go...

I talked to the guy who was winning for the past several years and he told me, and explained it like I did above, that the 914 needs to have the front just 1/4 inch higher...

this is how I learned it...trial and error...and he was right...I can brake alot harder now, and I can reset the car faster...
