Guy's I'm in really bad need of help! I need some advice on what spring and shock combo will work best for me! We seem to have a really good set-up for a tacky track but when it goes dry-slick everything foes away! I'm not exactley sure what we have, It's all written down I just don't have it with me at the moment! We run a IMCA I-Stock car and must weigh in at 3100lbs. We currently weigh 3120. I don't think the car is rolling over enough in the corners and the weight transfer from front to rear seems to be off. Any help is appriciated!

Our track goes dry-slick all the time. Our I-Stock set-up is:
1000lf, 1100rf, 200lr, 175rr for springs. Shocks are Proshocks wb75lf, wb76rf, wb94 both rear. Tire pressures we use 19rf, 15rr, 14lf, 14lr. We run 3 offs all the way around, sometimes going to 2 off lr for really slick. IMO minimum %s are 52 rear and 51 cross. We run 50 to 100 lbs of lead dead center in the trunk to make weight.

Well, we have pretty much the same set-up!
Springs:RF1100 LF1000 RR175 LR200
Shocks:RF WB76 LF WB77 RR WB94 LR WB 96

I've been thinking about changing the right rear and left front shocks. It seem logical that a RR that compressed quick and re-bounded slower and a LF that re-bounded quickley and compressed slower would help transfer alot of weight to the rear.

I put a call in to Afco when I got my shocks and springs. The tech guy told me to run 1000 lf, 1100 rf, 225 lr, and a 200 rr. As to shocks he said a 6 valve lf, 7 valve rf, 3-5 valve lr, and 4 valve the rr. Now I have not had a chance to try it out yet but thatís the info I got from their tech support. I run a 3000 lb metric with a 4 barrel on 3/8 tacky track.

You can try this combo
Springs
LF-1000
RF-1200
LR-250
RR-225
Shocks
LF-5
RF-3-5
LR-5-3
RR-4 or 5
100-140 lbs. bite
54% rear
This works real well on dry slick tracks.
Remember that track banking also effects spring selection, the above combo works on a dry slick track and medium to high banking.
As eveyone says " this is a good starting point" you must tune your car to track conditions and driver style.

Thanks for all the info guy's! Keep it coming. I think that our springs are about right, but need to work on the shocks! The track that we run is banked, Medium banking I would say.
