With high end shocks I have zero issues controling that size of a spring. Honestly I'd say the ride quality is as good and smooth as stock.

The car got re-corner balanced today, ignore the salt! We had snow the last couple days.

 

so what size tires are you running? and what are your jrz settings?

 

255/40/17 on 17x9 all the way around

Before the spring change the shocks were

front
HS- 9/14
Lo- 4/5
Rebound- 5/14

Rear
HS- 9/14
Lo- 3/5
Rebound 7-8/14

Now since I swapped springs everything is back to the middle setting of 7/14 and 3/5 all the way around. Got to wait till it warms up to do testing.

Shock settings don't translate to another car so I'm not sure why you asked but none the less it's posted above.

 

I think your wins speak volumes for you Josh. Congrats!!
I'm not all warm and fuzzy about the look but my "S" would be a dog in your events so.....keep up the great work and continued success on the track.
