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 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... =[
