Suspension Question

Hi! I have a 1987 CRX SCCA ITA car. I was wondering what you guys suggested in terms of torsion bars and rear springs? I know these cars have excellent roll centers so there is a wide range of rates that will produce very neutral handling characteristics. Which do you feel will allow for some slight throttle-off oversteer. Also, I want to decrease camber changes as much as possible in the front end on corners of 50MPH and greater. How much negative should I have dialed in?

Thanks in advance for your help!

Good questions, the CRX is a great car, for this.

For auto X I would highly recomend
-.5 to -1.2 front camber, and 1.5-2.0 in the rear.

some positive toe in the front tends to bring out my rear a bit
try to keep the rear toe negative a bit, also you want to have the car come out to the rear? keep the stock sway bar up front and add a 16-19mm rear bar. As far as spring rates you are stuck with one unless you are running adjustable suspension.

What springs are you partial too?
Neupseed and Eibach are the champs for auto X, IMO

Here is what the car has currently:

Tokico shocks
OPM camber plates
27 mm torsion bars
550 lbs springs in rear
OPM adj. rear sway bar

My question comes primarily from the fact that I am toying with the idea of going to coilovers in the rear. Keep in mind that this car will most likely never see an autocross. it is a road race car so the suspension is set up differently. Autocross cars are set up for quick transitions whereas road race cars are more designed to slide.

You will benefit from coilovers for road race, but I suggest, a very good coilover setup, actually one that will allow you to have them valved specifically for that reason. I would also consider, downgrading the front bar, to 20-22mm I would think you will suffer some nasty understeer with that. Bilstein Sport allow for valving as do progress and Koni. I would consider Progress, for the support, and the R&D they have done on Hondas.
