Spring Rates?, Anyone know? Options

[Gen6-GT]

Anybody out there know any of the following spring rates:

Stock 1995 Celica GT springs
Tein S-tech lowering springs
Eibach Pro-kit springs
Eibach Sportline springs

I'm trying to decide what to get for my Celica. I am going to get a set of KYB GR2's for it, and plan to lower it with new springs. I've heard that the Tein's look nice, but are only slightly stiffer than stock, meaning bouncier ride and bump stop thumping, but are the Eibach Sportline's any better? They both drop about the same.

Thanks.

Well its not exacaly what your looking for and sorry its a lil messy but im sure it can help you guys out some and sombody should include this kind of info into a sticky

Tein: S Sech Springs - Spring rates: Front 3.9kg/mm Rear 2.2kg/mm Drop: Front -36mm/-1.4in Rear -24mm/-0.9in
SS Coilovers - Spring rates: Front: up to 7kg/mm Rear: up to 5kg/mm Drop: Front: from -1.1in to -2.4in Rear: from -0.9in to -1.4in


Tanabe: SUSTEC NF210 (NF = "normal feeling" which are stock spring rates just lower) Spring Rates: Front 2.9 kg/mm Rear: 2.3 kg/mm Drop: Front: -1.0in Rear: -0.8 in
SUSTEC DF210 (DF = "Dress-up Form" which is 10%-15% stiffer spring rates) Spring Rates: Front 3.1kg/mm Rear: 2.8kg/mm Drop: Front -2.2in Rear -1.5in
SUSTEC GF210 (GF= "Grip Feeling" which is 20%-30% stiffer than stock and more performance oriented) Spring Rates: Front 3.5kg/mm Rear 3.0kg/mm Drop: Front -1.0in Rear -0.8in

This is great information, the Tanabe NF's are supposed to be stock spring rates, so I can see the relative difference now with Tein's, and I just need to find out about the Sportlines and Prokits now.

Stock = 2.9kg/mm front, 2.3kg/mm rear
S Tech = 3.9kg/mm front, 2.2kg/mm rear

Something tells me I'm going to want something more in the ~4kg/mm front, 3kg/mm rear range. About 30% stiffer than stock, to keep me off the bumpstops and prolong strut life.

Prokit may be the way to go, I like the look of the Sportlines but something tells me they're just too low for bumpy roads.. unless they have a REALLY high spring rate.

THANKS!

Stock Toyota // Front: 2.9kg/mm Rear: 2.3kg/mm

Tein ST202 S-Tech Springs // Front: 3.9kg/mm Rear: 2.2kg/mm

Tein ST205 S-Tech Springs // Front: 4.3kg/mm Rear: 3.7kg/mm

Tein SS Coilovers // Front: up to 7kg/mm Rear: up to 5kg/mm

Tanabe SUSTEC NF210 // Front 2.9 kg/mm Rear: 2.3 kg/mm

Tanabe SUSTEC DF210 // Front: 3.1kg/mm Rear: 2.8kg/mm

Tanabe SUSTEC GF210 // Front: 3.5kg/mm Rear: 3.0kg/mm

Tanabe SUSTEC Pro S-0C // Front: up to 8.0kg/mm Rear: up to 6.0kg/mm

some more info to add:

ST205 RSR Spring Rate // Front: 4.0kg/mm Rear: 3.4kg/mm

ST205 TRD Spring Rate // Front: 4.4kg/mm Rear: 3.87kg/mm

ST202 TRD Spring Rate // Front: 4.1kg/mm Rear: 2.9kg/mm

i switched from Tein S-Techs to ST205 RSR springs.. so they're 3% stiffer in the front and 55% stiffer in the rear compared to Tein springs. the rear feels better now, just what i wanted.. now i need a rear strut bar and sway bars and i'm good as far as suspension goes. i need to put some washers now on the rear hatch stoppers to tighten the hatch door to keep the hatch from buzzing from the stiffer ride

i'd also like to know where this was obtained:

Stock = 2.9kg/mm front, 2.3kg/mm rear

cuz there are two kinds of stock setup: with sport suspension and w/o sport suspension
