Im looking for lowering springs that will give me about atleast a 1.5 in drop with a higher spring rate. Also i'm running 17 inch wheels so which manufacturer should I go with.

 

Other than H&R Sport Springs @ ~1.25" I don't know of any springs that drop the car that much. Any reason why it has to be "at least" 1.5"? Your only other option is to get adjustable coilovers. And BTW, post questions like this in the Suspension section.

 

i think tein drops 2"

 

i have had really good results w Eibach Pro Kit. the rate is just about right for street/track up 33% at 350 fr and 255 rear. my optimum ride height for the fd is 25 inches at the front and rear wheel wells and the springs come within less than an inch of that height. the Eibachs work well w stock shocks and 29 front 27 rear air pressure set cold. the rx7 store and pettit sell them as well as other vendors.
enjoy,

"my optimum ride height for the fd is 25 inches at the front and rear wheel wells " Sounds more like a lift kit than a lowering kit :P.

I have the Eibach Pro Kit and love them!

 

Nope.

 

tein drops around 1.5

 

Uhh...howard's talking about 25 inches from the bottom of the fender lip to the ground. Hold a yard stick at the center of the wheel well, and measure to the ground.

 

Tein drop is 1.5 as 89rx-7gtu said....Tein's are stiffer than the Espelir springs which are also close to a 1.5" drop....

 

if you drop the car more than the eibachs you will have a camber problem.

as the fd suspension goes into compression the wheels gain negative camber. that's like all real race cars. this camber gain positions the critical outside (in a turn) tires upright even as the car rolls.

as you lower static ride height with shorter springs the camber goes negative to the point you can't adjust it out.

at 25 inches of ride height your camber adjusted all the way toward positive will still be 1.2 degrees negative. if you lower it more you will have more than 1.2 degrees negative camber and wear out the inside of your tires.

i run 1.2 degrees at 25 inches and it works super on the street. (you want more negative camber on the track but only at the track.)

have you looked at a car running eibachs? it is LOW. close to 25 inches. unless you put rollers on the bottom of the car you don't want to be any lower.

That's not true Howard, at least on my car it isn't. My front fenders are about 25" above the ground and the shop had no problem getting the fronts to 1.0 degree negative camber up front. Rears are at 25.5" and 0.5 degree camber.

 

I have 2.7 negative front and 2.2 negative rear.

 

1.2, 1.0, 'not alot of diff. the point is if you go materially lower than 25 inches you will not be able to adjust back to a reasonable static camber setting. the fix would be adj length upper control arms.

I just got my eibachs yesterday. I'll put them on saturday and let everyone know how it turns out.

 

I got Eibachs and I noticed a drastic change in handling. Even though I do get SOME rubbing on the inner front fenders with only a 1" drop.

It's not as low as others, but I don't see how other FD's can go lower without rubbing since I already do. It looks classy. And once you get some nice wheels on, it'll look even better.

 

How do you guys handle going in and out of driveways with your car 1.5" lower than stock?

I angle in and out now but in some places I still end up rubbing a bit on the bottom of my front end.

I'd like the better handling but I really see my only option as fully adjustable coil-over setup that allows me to go back up to at or near stock ride height.

 

how is the ride comfort of the eibachs compared to stock? also does eibach offer both pro-kit and sportline? or only the prokit

 

I just put eibachs in Saturday. the ride quality is noticable, but not significantly harsher than the base shocks.

The one inch drop and increased stiffness seems to reduce body roll significantly when taking turns/corners at high speeds.

My only issue is that my back right is slightly higher than my back left (a bit less than 1/2 an inch).

Overall, pretty easy install.
