Hi,
I did searches and got contradictory info. Does anyone know the I.D. of our stock R springs?

Its just above zero here and I've got a foot or so of snow, so please, please don't suggest that I crawl under the car and measure them!<LOL>

Thanks!
John

 

What exactly are you trying to do?

 

Hi,

Well, good question. I was trying to find out if there was any source of springs in different lengths and rates that could be used on my ITR. From the information I've been able to find, on 'dedicated' aftermarket springs, the rear spring rates are very soft compared to the fronts.

I would like to lower my R slightly and stiffen the rear relative to the fronts to help the car rotate easier.

I realize that I could use Ground Control threaded collars and any 2.5" I.D. spring, but I'm just exploring an alternative.

Thanks,
John

 

That's really not going to work out the way you think it is.

Just buy the Ground Control coilovers. It's easier, cheaper, less frustration, and opens up plenty of spring options.

Remember that you're going to need to address the shocks if you intend to go bumping up the spring rates.

 

you can't, and or it is really expensive, to find different rate springs in a non flat grind. Which is what you would need.


Just get some GC's with 8 or 9 inch spring, 7s would probably work too. Whatever they normally come with, get an inch tall spring for the rear and the front, that will insure that you will be able to get the car close to stock height.
