Looking for a little help on some springs. I'm looking for a set of springs in the 650ish/150ish range that sits no lower than an inch below stock ride height. Ideally, I'd like it to be no lower than the stock springs ride with the front on the lower perch and rear with the hose mod. I don't mind putting the stock buffer back in the rear and moving the perch back up. If anyone has any suggestions, please post up.

Thanks

 

Why don't you just keep the stock springs and get some koni's. That way you can do the heater hose mod in the rear and the lower perch on the front. I have read that it's about a 3/4" drop doing this.

SLP #70009 springs... heres mine installed with the SLP shocks also.

 

I've got Koni SA/stock springs currently but I'm wanting a somewhat higher spring rate without going any lower than the lower perch/hose mod drops you which is where I'm at now. The research I've done points to using a coilover setup of some kind which isn't bad since they use commonly available spring sizes that you can switch out as you wish. But I wanted to see what was out there in a stock style spring first. Thanks for the reply tho.

And you are right, you get about 3/4in or so. It actually looks like what the car should look like from the factory (so we can lower them more lol).

 

They don't exist. Nobody makes 650/150 to start with. You could go coil-overs and get those rates and set your height... that's the only option.

However, if you are not married to those rates exactly you have a lot of options other than coil-overs. My springs which are derived from what I race on are 550/150's. H&R's are about 600/200 and there are a litany of other, but they are pretty much all progressive which is rough for tuning a car in since the spring rate is always in a state of change.

 

And here is the spring rate on SLP:

FRONT REAR RIDE HEIGHT DROP
SLP Level 1 Progressive 223-448 97-136 0.75"
SLP Level 2 Progressive 300-450 115-185 0.50"

Sam might be able to locate a spring your looking for but I'm thinking you want coli overs too to get what you want.

 

The options Sam mentioned are both good springs. However both lower the car a decent amount. If you are looking for stock or stock-like height, coilovers are for you. The positive is you can run pretty much any linear spring rate you want.

 

I'm not dead set on it but I guessed at it being a good place to start for a good handling street spring. My car is a little nose heavy with the twin turbo system I built but I've compensated with a relocated battery and a rebuilding a few things to make them accommodate the system. As of this writing, I don't know what it weighs. I think you are right in that coil overs will probably be the direction I go. I like the huge variety of rates and lengths of 2.5in springs out there. I am competing in road race/autox/drag race event in May and I can't swap tires in my class but I can swap springs (strangely enough) so that might offer my a good deal of flexibility.

That said, do your springs maintain near stock ride height which I need for ground clearance?

 

His springs are a 1.3" drop.
