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.

I was just searching for this last night with no luck If I can I will email eibach tonight at work and try to get the info from them

I got grouind control coilovers, which use eibach springs. I got to specify my spring rate.

[CelicaB]

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
SUSTEC Pro S-0C (coilovers) Spring Rates: Front up to 8.0kg/mm Rear: up to 6.0kg/mm Drop: Front: -1/2in to -2 1/2in Rear:-1/4 up to -2in

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!

TEIN is the best suspesion imo you can get

much better then eibach

can you give a reason for your opinion?? I have had great luck with eibach springs in the past, however they have always been part of GC.

What is the stiffest drop springs around?

[95ST]

according to our local shop, prokit ~15% stiffer than stock, and sportline ~40% stiffer than stock.

Does anyone know what stock spring rates are?

My old ground controls on my last celica were 380f/260r I am hoping for something with a little better ride quality.

what do you consider quality? handling or comfort?

HAHA Im still trying to figure that out. I love the feeling of a stiff car, that handles like a go cart, My last 2 cars were both stiff enough that you could take off a tire and take the jack out and the brakes would not touch the floor.

Im thinking I want something mild, but Im not sure I was thinking of Pro kit, undecided on shocks, and the ST sway bars, and I would make up a couple of strut tower braces. I made a x brace in the trunk and a 3 point front strut brace for my integra. Does anyone have a setup like this? Have you auto-xed it?

Does anyone know what spring rates the kyb gr2 shocks are valved for?

This is solid info, thanks!

The this brings a bigger question, what brings better ride quality, the sportlines with the 2" drop and the higher spring rate, or the eibachs with a 1" drop and 15% higher spring rate?

lower drop = more bump stop polka
lower spring rates = bouncy bounce tango

What's worse?

[Kwanza26]

If you match up spring rates with dampening... you can run stiff higher rate springs and still maintain a good ride. The typical "bouncy" with lowering springs is because lowering springs don't match well to the soft factory shocks, so the springs take a majority of the absorbtion. KYB gr2's are considered soft also. Ride height doesn't really affect the springs rates... it's just 6gc Celicas don't have a wide variety of choices when it comes to different types of springs/rates...

sorry player, i dont agree with that AT ALL.

[lagos]

tein has good stuff and bad stuff too. i dont think their springs are any better or worse then eibach and i doubt there is a member here to had teins and eibachs installed at one point, to give a fair comparison.

[Gen6-GT]

I called KYB and asked them for their recommendation, and they said the main point is not to lower the car too much with their GR2's.

They said the Pro-kits were ideal, and the Sportlines were too low.

So KYB GR2's and Pro-kit is the way I'm going to go. Eibach is pretty expensive, but I trust that their springs hopefully won't settle as much as a cheaper set of springs.

Next month - Suspension Techniques sway bar kit =].

BTW, what width are the stock GT rims? Are they 15x6.5 or 15x7? If they're 15x7 I'm going to cry, I just bought new 205/55/15 Potenza RE950's last month, and if the rims are 7" then I could have done 225... =[

CRAAAAAAAAAAAAAAAAP!!! Anyone want to buy a set of RE750's (not RE950's) with less than 1000 miles on them??? =[

They were on sale at Costco, I got the whole set for $402 out the door, with lifetime balancing and rotation. Damn...

def right, I wish manufacturers would list the acurate specs of these products, koni will revalve the yellows to match your springs, I was running 500f/450r in my integra with revalved koni yellows and the ride was great however very stiff.

Does anyone have sportlines with koni's? Or has anyone inquired to find out if we can find agx's to work with the celica?

Stay with the 205's... 225's are too big... you'd have to run a 45-50 series tire to compensate otherwise you'd have some thick sidewalls not to mention it'll hug over the wheel a bit. 225/45/15 isn't a common street tire size either.
