Springs question.

Is there any aftermarket springs set that improve handling but not lowering the car?

Saleen and FRPP have minimal drops (1/2" or so) and they improve handling...

I'm not sure about Steeda, I can't remember if they do or don't. The other questions you have to ask yourself is how far are you going to push the car? Far enough that you might need a drop, or far enough where you shouldn't be spending any money 'cause the stock suspension gives you what you need?

Steeda have a very minimal drop in the front, while getting rid of that rear wheel gap in the rear.

The FRPP drop the car more than an inch and a half!

I agree with Maverick, FRPP K Springs are very much more than half of an inch. More like an inch and a half...

I haven't seen FRPPs drop compared to the Eibach Pro drop. I didn't think they were the same.

Are you guys sure?

Yes, the FRPP's drop the car down 1.5 inches, it's very noticeable. If I lower my car I will probably go with Steeda Sport springs, they lower about 3/4 inch or so.

Ok so Steeda or Saleen is the less ones. I am looking the high once because of 4 reasons
1. I want improve handling.
2. I have got +24mm offset Razors with a new GT500 spec +2 so they are really +22 offset and the tire going out about 1/3 of inch out the car body line.
3. The worse gap is on the back but I am considering new tires on back 20R/35 what will increase sidewall by about 0,9 inch compering to stock setup
4. Here where I live it is rather recommended to have higher then lowered cars. The present stock setup is perfect for road conditions I meet everyday.

Good point... maybe you don't want to drop it but beef up the sway bars.

Also, why do you want better handling? Road events? If so, sway bars might help you more than springs according to what I've read in this forum from the road guys

All the changes are connected with hopefully coming Saleen blower next spring. Here in Europe we do not have a lot of straight roads but a lot of cornering I need then good handling.
I am planning sway bar improvement as well hmm …. what can I get if I leave stock springs and put Tokico D spec? have that set any sense? will they fits stock springs?

yep the tokico will work with the stock springs. What tires are you running? Add more beef there as well for better handling

285-305s would help you...
D-specs will make the ride either softer or stiffer, the combination of the lowering springs is what would improve your handling during cornering. I don't think the shocks/struts by themselves would do much for your handling... Your thoughts people?
If you don't want something radical, buy the Saleen suspension setup, available for $599-$799 (you have to look around). It's a good compromise between drop and increased handling.

Shocks/struts only dampen the motion of de/compressing the springs. Stiffer shocks are only going to keep the springs from changing length quickly, or dampen the reaction time. If you hit a bump or make a sudden turn the spring can't move as much in the same amount of time and it'll feel like a stiffer suspension. But in a steady-state corner like a sweeping bend it wouldn't really affect body roll because the spring is given plenty of time to reach its equilibrium. Right now your dampers are matched to your current spring rate and thats really how you should keep it. I'd get the swaybars unless you plan to get both springs and dampers. I saw a big difference with just those before I installed the springs.
