I asked in the wheels/ tires/suspension part of the forum, but nobody could give me an answer.

I figured I would ask the more experienced people when it comes to stripped cars.

Its an 86 sport model on stock black springs on blue shocks. 255/40/17
Interior is stripped entirely and there is 1/4 in the gas tank.
Cage not in yet, but it will be very lightweight.

My car has almost 10 inches of height to the sideskirt and 4 inches between the tire and the fender.
I dont really want to do coilovers, but I will if I have to. I wanted to do kyb agx with stock springs and camber plates, or mabey use eibach or gf210s if I have the money.

I am guessing camber/caster plates will give me an inch; coilovers will give me 2 inches but I'll still then only be at stock ride height. I may have picked up an inch as most with the new wheel and tires.

Gahhhhh!!! I hate driving a truck

Well, the thing that coilovers give you is the adjustability to corner balance the car. otherwise, you can just source some shorter springs (search: lowering springs). Paying out for coilovers really depends on what you are going to be doing with the car.

Which brings us to the question - what are you going to be doing with the car?

Two things to watch out for are a) rubbing, and b) camber changes. If you lower the rear you will want to install an adjustable camber bar in the subframe and camber plates for the front.

^^^^ Yup, one way or another, you're going to need to do something adjust that ride height, be it lowering springs or adjustable coilovers. You could probably pick up GC coilover kit to go with those AGX's as the most economical route. I would worry that lowering springs, which typically lower about 1", won't be enough. I'm also not understanding how camber plates would "give you an inch". Camber won't change your ride height... they'll just compensate for however much you end up lowering it otherwise.

I am surprised though that simply stripping the interior made that much difference. You've got a motor and everything in it, right?

I would investigate what really makes the car that high. The 17's dont help, and possibly dont hurt much either. Just taking the interior out did not raise my car when I built it. Something does seem fishy though.....

Standard street lowering springs (Eibach, Racing Beat) will give you -1.5" at best. I would not reccomend a true adjustable coilover setup for a street car unless you dont care about having you teeth rattled out. And like Wranklin said...what are your plans for it. Race only or street....

If that's a picture right after the car got put on the ground from being jacked up that can have an effect. You need to roll it back and forth for it to settle. Or if it's an uneven surface that'll affect it too.

There are no rear camber plates (and no such thing as rear caster), as they're shocks, not struts, so they've got nothing to do with camber. I think what you mean by them giving you an inch is that they're thinner, correct? Anyway, camber plates are meant to work with race springs and the stock type springs won't fit on them, as the upper seat will be much smaller in diameter.

When I stripped mine it looked that way too. Buy some coilovers, the flexibility is nice vs a fixed shortened spring.

what are your plans for the car? road racing?

obviously you need to get the car down to stock ride height and then lower it a bit from that point. low is fast.

keep in mind 2 things:

1. spring RATE is of the utmost importance. do you know what rates work for the FC w whatever sized tires etc you are planning to run? do you know what your spring options are given the rate target?

2. as you vary the ride height the camber changes. camber may be the second most important factor in going fast and staying out of the weeds. remove the rear spring. set the wheel at ride height you want to run. check your camber. then put the wheel into bump and plot a camber curve. if it isn't what you want you'll need to do some suspension re-engineering.

3. coil overs on your car can be purchased inexpensively from Ground Control and you can get any spring rate you wish. talk to them re spring rate.

4. weight distribution is important. you want as much rear weight as possible

good luck,

hey howard...where in Wisconsin are you (roughly)? What and where do you race if you do...just curious if we may have crossed paths somewhere.

The car is definitely settled.
I am referring to camber plates having a thinner profile.
I plan to have camber plates at the rear, and camber/caster at the front. do camber plates really not help in the rear?

This car is a street car, but its a weekend autox and my track car. I have no care for how comfortable it is.

I have never used coilovers, will they be ok to use without a helper spring?

I would like something cheap I was thinking megan racing, but people seem not to like those.

Right now I'm thinking kyb agx with gc coilovers and camber/caster plates. What about tein camber caster plates?

I will be running (i can change this) 255's all around.

there is no such thing as a camber plate for the rear...You can only adjust it by use of a single camber link or the two link system offered by AWR. If anything, camber plates amy add height...as they go on the top of the upper mount....correct me if I am worng here guys.

Ground control offers a set up with camber plates on it. Ussually you get a complete set. That would be a bit easier than buying individual peices. In exppensive would be Tein or JIC...they ussually come up used in the for sale sections.

You can get solid top mounts for the rear, but they'll be fixed and not adjustable like a camber plate, because as has been stated before, the angle of the shock does not effect camber.
