I was wondering how similar or different the GT and ST suspensions are. I know they probably have different spring rates and shock valvling, but was curious if the mounting points were the same. The sway bars are of different diameters, but I know they interchange fine. Tie rods? End links? Anything or everything swaps fine?

For instance... say I picked up a nice set of aftermarket springs/coilovers, would they be interchangable between the GT and an ST? Assuming that the mounting points are the same, it seems that a nice upgrade to an ST might be a set of struts from a GT (could likely find them cheap in a junkyard).

how would you know if your car has the spors pack?

If you are lucky enough to have the window sticker, it will show up there as a line item option; otherwise, you can take you VIN # to any Toyota dealership and they can tell you what the original equipment was on your car. From what I understand, the 'sports package' came with leather seats and a 10 speaker sound system, in addition to different springs/struts along with some suspension components.

Shock valving and spring rates are the same...


I am not sure I agree with you on this. For sure the shock valving is different... not so positive about the spring rates, though. It was a common 'upgrade' for some of the (then) ES Celica ST guys to run a set of GT shocks up front and a set of GT convertible shocks out back. Jeff Cashmore comes to mind, and iirc, he won a national championship in an ST on that combo. Valving was different because of the weight differences between the models. See this link for more details : Per Schroeder's Celica - 10/9/2002 journal entry (near the bottom)

SpedToe169, you did answer the main thing I was hedging at, which was interchangability between the models. I have seen a guy on here trying to get rid of his GC coilovers, and had been really thinking hard about them, but he has an ST, and I have a GT. Looking at the GC site, there doesn't seem to be any distinction between the two, so i figured they were alike... but I wanted a bit of confirmation before I made a $$ commitment.

I am still waffling on whether I want to do GS or STS this year. Short term, GS wins out money-wise... but STS has a lot of plusses. Also, the Koni's going on my car either way are going to be custom valved for autocross, and that is the high-dollar investment, and the first in line.

Out of curiosty, what spring rates are you running, F/R, SpedToe169? i saw in another thread that they were %50 stiffer than recommended for the street, but that doesn't tell me much. Judging by what some front-running Neons are using, I was thinking 550-650 on the front, and about 250-350 on the rear, but that was going to be more a starting point than anything. Thoughts on what you have/what you'd change? Note that I am running a bit more weight than you as well... Offhand, if I pick up a set of used GC coilovers, do you know if they will let me send in the old springs in exchange for a set of my choosing (perhaps for a small fee...)?
