i have a set of tein RA coilovers. i am considering removing the helper springs and essentially leaving the perch in a stationary position. this will negate height adjustablilty but i feel the shock performance will be better and more consistant.

the spring rates are 14k front/ 10k rear and the shocks are obviously valved specific to this DC2-R application. i want to change spring rates to 10k/8k.

i called tein usa and it was suggested to only change spring rates by +/- 2k to still suit the "stock" shock valving... i asked it it will damage the shocks if i dropped the front rates by 4k, and was told NO it would not.

however, i was warned that the rebound might be too stiff for the new lower spring rate and when the car dives (for instance under braking) it will not rebound and come back as quicky, which will hurt steering response and stability.

* MY QUESTION is will this in fact be a noticable performance issue? this is a track/recreational car and performance is my first concern which is why i am considering this "upgrade". but i am not trying to shave tenths off times.

i think a 4k difference front-to-rear is too high and i also feel the rear springs at 10k are too stiff for the weight of my car, it becomes choppy which is not good for handling/predictability/ or control.

so should i have the front shocks revalved for 10k spring rates, or not bother? thanks
