Anyone know the spring rates for the TMC springs offered in the Spec 7 racing suspension package?

 

Have you tried calling TMC?

 

The story is that I bought the springs here in Houston from a retailer and have had them on for about a year along with the front bar and bushings etc. I remember being told by someone that they were around 145 front and 120 rear. I have noticed that front of the car seems to be a bit more squishy than it used to be. I also installed tokico blues at the same time because I thought I would be racing the car in spec 7. Found out later that se models were not allowed and so decided to keep everything so I could use it as a track car. I want to know the spring rates because I was thinking of upgrading with the eibach sports in the front who I know to have 175 # rates. I would also replace the front blues with a new set. What do you think?

 

I would go with higher spring rates in the front like 350 for a track car.

 

TMC is out of bidness.

 

gsl-se suspension is not allowed in spec 7? is it allowed in ITA?

 

Not in ITA either. The SE is classified in ITS.

 

thats horrible news, that means my gsl with gsl-se will get beat on by 2nd gens and 240z's

 

dont' forget e36 bmw's.

Actually, a 12a car wtih GSL-SE suspension parts is really just a bastard...that wouldn't qualify in ITS either, as the car classified there is the 13b...right?

 

yep, so i'm not sure what I would be in....looks like its solo2 and solo1 for that car...

 

I don't think there is a class for your car except some sort of modified class. Either that or you put a 13B in it and race in ITS. It would be a formitable platform in that class though, since it is lighter than a GSL-SE.

 

So when it comes to IT prepping tell me what is differnent about the GSL-SE suspension?

I guess the brakes would be the major thing. LSD was optional on GSLs.

Spring rates and shocks are open in IT...so that doesn't matter.

Go back to the original GSL brakes and the subsequent bolt spacing and there is no reason you couldn't run in ITA.

 

True, Just change out the front brakes. You could leave the rears. Or you could run the car in EP with a few changes.
