figure this be the best place to ask, as its for an itr, many itr owners use this setup, and most of you in here are pretty knowledgeable

i know you can order your koni yellows custom valved to your custom rater ground controls, but do koni yellows have a limit to how hi a spring rate they can run?

i want to run 12kfront an 14k rear, that be 670lb front an 780lb rear springs, is that to hi a spring rate for the konis to be revalved to?


if not where is the best/most capable/trustworthy place to order these from


also dont think there will be a problem with these but safer to ask, i want to run these tein pillow ball mounts http://www.tein.com/products/upper_mount.html , any problem running these? obviously the ones in the picture are incorrect, they sell them specificly for itr's

 

i have the same set up.... yellow koni with ground control cc with top mount .... the ride
quality is really poor./// imo

 

sounds like you have ots rates and gc top hats

my setup will be nothing like yours

 

The Koni "Race" (or SPSS3) shocks will handle rates up to around 1000lbs. If you go higher than that (or want a slightly better shock), then look at a Koni 2812, 3011 or something.

 

spss3 should be fine for your setup

 

i can just order off the shelf koni race spss3? no need to revalve? excellent news

thank you

 

this is correct. the standard sports start getting a little light in the rear over 500lb/in
