Suspension, best of both worlds?
 

I like to take my RX7 to Rally X days. There isn't much done to it suspension wise. Because the suspension is soft, it goes over the bumps pretty well.

I recently took it to a small road course with a set of yokahamas and had a blast however there is a lot of body roll in the car probably because of the soft stock suspension.

I was thinking and drinking and thought,
Hey why not have 2 sets of suspension for both Rally x and Auto X. The rear consist of a solid axle. I have seen coil over conversions for the car. Just put the coil over spring rate that matches the day.

The front isn't bad also, Disconnect the brake caliper, remove both bottom bolts, remove the top bolts that hold the strut in, Put in other strut with correct spring rate and bolt everything back together.

The only problem is ride height but how bad would it really be if I just kept the same ride height with both setups (or some sort of compromise between the two)

Sway bars could be connected and disconnected.

I don't use the car for DD purposes.

Would this make sense? Can anyone give a reason to do this or not to do this or any more ideas to make this possible?

I only have one play car and I am trying to get the most out of it.

You will be making compromises doing this I think, I would try to focus on one discipline or live with the body roll. Stiffer sway bars could probably help you in both disciplines though

A good rallycross suspension will work extremely well on asphalt, too. The goals are the same.

Since alignment doesn't matter much on dirt, I set up the suspension for good handling/performance on dirt, and then set the alignment for pavement. This ends up being slightly negative camber in the front.

Why not get two cars?

I'm actually doing a budget spring/shock combo that I think is exactly what you want, but I have to test it myself after DGRR.


It uses a progressive spring and adjustable koni Yellows, and slightly upgraded sway bars/bushings and a panhard bar...


I *think* it'll be just what the doctor ordered, but I could be wrong.

That's the setup I have now. I have a Mod Rear car, and if I can put together a stock port 12A, a Prepared Rear car.
