Default how hard springs on a ITR????

Hey guys

im going to uppgrade my coilovers now, running on K&W V2 and thier springs(9k fr / 6k rear). Im going to buy the Spoon Adjustable Damper Kit thats for sure.

My question to you is which springs do you run on(I drive as much as I can on tracks nevermind the DD, that i dont care of). A-J racing recpmmend 18kg front 16kg rear feels quite hard. so what is your opinion???

1000 lb in the front and 900 rear. Ok I guess, it would make for a pretty neutral setup.

Or if you wanted more oversteer, you could always try something like 800ft 1000rear.

I personally wouldn't daily drive with either setup if this car is your only car. I'd run a compromise setup like 600/800, which would still be approaching the limits of civility.

That's because you're only running 500ft/330r lb springs right now.

But 'hardness' has a much to do with shock valving as it does springrates. Instead of focusing on stiffness, focus on making a great handling car. 600/800 is a fantsatic setup if you are running oem bushings, no cage and sticky street tires.

Without a cage I presonally would not run any spring over 1000 lbs.

Im not trying to question your comment but was just wondering why you feel that running over 1000lb spring rates are not good?

I'm not trying to disagree with you or anything but just asking in the interest of learning.

I don't know just how much the ITR chassis will handle sans rollcage (rumors are around 1000lb), but once you start running incredibly high springrates the chassis starts flexing instead of letting the suspension do the work. And that's not good.
