Rally Project - Suspension Question

[AadosX]

I picked up a fastback shell that has too many little dents that I don't want to deal with fixing, as well as pretty shitty paint (faded) so I've decided to make it a rally car for fun, I've always wanted to do this and we have good trails close to me.

Anyways I'm trying to think of the best route to go suspension wise. I think I will do hicas sways.

What is the stock spring rate for S13's? Also, what aftermarket springs lower the car the LEAST? I had GR2/Prokit on my last S13 and it seemed pretty jacked up. I think that just getting some AGX and keeping stock springs might be the best bet, but if there are any aftermarket springs with decently stiffer rates, that don't lower it more than an inch or so, I will go with that. I can't have anything TOO stiff or too low.

The car is going to be on a tight budget just because I don't think it's worth spending much money on, I will be beating the crap out of it and fixing whatever needs to be fixed cheaply. It has a sunroof that will be removed, a plate will be riveted in its place. I'll also be fabbing up some rough skid plates up front to keep rocks out. I've had a little experience rallying my last S13 for the fun of it, so I know what to expect.

What do you guys think?

on a rally car you don't necessarily want a really tight and hard suspension. in fact, i would probably keep the stock sway bars. i have a galant vr4 that i was building for production class, but thats on hold until i get a better job (just to get a rally car to meet the rally america safety specs can really cost an assload)

Look into other (heavier) nissans for springs. Maybe Z32, R32, or possably even a FWD chassis.

Yeah I knew I had seen the spring rates somewhere before but couldn't remember where. Sometimes certain things are hard to search for. Thanks.

Anyways, I'm thinking beefier sways because that will help with body roll, etc, but not make the car any stiffer as far as taking jumps, and wont force me to lower the car.

89 fastback, Stock springs with GR2 struts. Most fun form of racing I've ever done.

the road i live on is bumpier than that

I had a bunch of fun with stock suspension on old bumpy dirt roads, I think some good shocks would have been the only thing I wanted to change for those roads. Rally is like drifting with jumps, so much fun.

Looks like rally-cross which isn't supposed to be real bumpy. It's the same as auto-x in that auto-x teaches you how to control your car on pavement with no possible damage to your car. Rally-x teaches you to control your car in dirt etc; without damaging your car. It's like stepping stone tofull blown rally. Well, unless you just fall in love with just rally-x.

hmmm, I don't think they don't have that around here. I'd probably do pretty well, IIRC, Iowa has more gravel roads than paved roads. I've lived on gravel since long before I got my licence. Some of the roads around here aren't even gravel, just dirt. Controlled slides on off-camber turns filled with potholes and large rocks are a daily occurance. I hit 4-8 of those daily depending on how I get to the highway.

Time to look for some rally-x comming up.

Preaty much. It's alot cheaper then full out rally, and still alot of fun especially with a 240.
