Ground Control Question
I'm thinking about ordering a set of Ground Control Limited Edition for my 90 Teg. Spring rates are 350/280. I know a lot of you guys have higher spring rates, but I don't plan on auto-x'ing. Just spirited driving through town. Would these spring rates be ok for what I'm going to be doing? Or would some of you guys recommend higher rates?
I'm planning to mate them with Tokico Illuminas. Thanks in advance.

That'snot to stiff, that is the neighborhood spring rate wise of the Eibach Prokit and the Comptech springs. That is about as stiff as I would go if you are not going to autox.

That's the stock GC rate. I have the rear 280 springs if you want to buy them from me. I upgraded to 350/400. 100x better. You don't know what a real suspension feels like until you get something that doesn't bounce all over the place.
Rule of thumb is to go with a stiffer rear end. Also rear is what makes your ride feel different. Personally I think 280 is ridiculously low. Especially if you're going to drop your car 2"+ which your probably are. Get some Koni's too.

350/280 is bouncy? I'm not going to auto-x, but you are saying that 280 is too soft for the rear. Just in case, how much are you letting your stock GC's go for? Thanks.

IMO, 280 is way too soft for the rear. Go with at least 300 and you'll be fine.

I kind of didn't want to spend extra for custom spring rates, but looks like I will have to. Getting 280 and setting shocks for stiffer rate wouldn't have the same effect? Thanks for the input.

No, my H&R Sport springs are 276 lb/in all around, and it feels very uncontrolled over really rough roads, even w/ my Konis.

but how fast would one really go down a really rough road...i hope not fast at all..and on smooth pavement i bet it feels very controlled ...

yeah well the roads are very bad here, including the part of the interstate that goes through here. There are MANY places where there are bad dips and bumps, and traffic is going 60-80mph, so what can you do? Unfortunately nothing but suck it up, or eventually get better suspension.

i have GC's on the regular spring rate with neuspeed koni yellows. you say having a stiffer rear end is better? if stock rates are 350/280, and i just upgraded the rear, 350/400, would that improve my handling a lot? cant you just buy two rear 400 springs from eibach (who makes GC's springs) for pretty cheap? anybody know where to do this/how much it is?

Yes you can buy ERS springs in pairs, I think they are around $100/pair but I'm not sure. I'm also not sure what length of spring you should get, as they come in a wide range of lengths as well as spring rates.
I want stiffer springs so that my car doesn't pitch up and down so bad over dips and stuff, and also so it doesn't bottom out like the rear of my car has been doing.

Well custom rates it is. Thanks for the informative post as usual.

P.S. Know of a good place that has deals on GC's? Or do I have to go through GC direct?

350/280 is fine for daily driving. If you're dumped, you will get a shitty ride no matter what your spring rates are, so I'm assuming you have more intelligence than that.
If you were an autocrosser or track racer, I'd say you should go with 375/450 or 425/550.
I'm currently on 380/450s with Koni Yellows... It's great...

The bounce has more to do with the struts/shocks/dampeners/whatever than with the spring. Actually, it's the relationship between the 2 more than any 1 factor.

That's more of a rule of thumb for tracked cars, stiffer rear ends on street cars that will be driven in the rain, snow, or by less than great drivers is a very bad idea. Throw in a rear swaybar and you have one dangerous combo for a car that never sees the track.
As a better rule of thumb, don't setup your car to promote oversteer if you don't know how to control it, or aren't driving where there are crash barriers.
280 isn't ridiculously low, I've got Comptech springs (up to 194 in the rear) and I am still chasing stock GSR's at the autox that have experience. Hardware is nothing, technique is everything.

i had the exact setup with illuminas. I used to have skunks with 400F 300R on the illuminas as well, the handling was better but the ride wasent as smooth as the GC rates. IMO these are good rates for the street when they are paired up with the right shocks.
