I drove my goat out to Great Lakes Dragaway in Union Grove WI the other night, a 65 mile cruise due north on my first track outing since '09. My combo seemed to be pretty trouble free on the street so I figured it was time to see what kind of ET's I can get with it. It was slicks or drag radials only night there, and I was able to run 8 solid passes without any redlights. I would love for it bite better off the line and then I'm sure I'd be able to run more consistent ET's. I was doing excellent 1-2 shift 10 second burnouts, but unfortunately every launch had me spinning a little but here's the results:

Best ET: 12.13 @109mph
60ft: 1.71


Worst ET: 12.46 @ 108mph
60ft: 1.90


My best RT was .047 on my slowest pass. I realize now that my rear shocks and springs are totally shot, the car doesn't squat like it should and I tried lowering the tire psi from 25 to 20 to finally 15 on my best pass. I did have a blast, won some and lost some match-ups, so I can't complain except I was hoping for high 11's like 11.80's would have sufficed. Anyway, what kind of shocks do you Street/Strip guys recommend for the front and rear? I've been looking at Bilsteen & Strange so far, will purchase some over the winter for next season as well as new drag radials because those to are 90% wasted.

Randall--
Competition Engineering--50/50 shocks in the rear will work and not break the bank.

Thanks for your input Bill, the ones I was considering are awfully expensive.

Hey Randall,

+1 on Bill's comment. My best time before those shocks was 12.1 and threw the Comp Engineering 50/50 on the rear and 90/10 on the front and knock 0.15 off my time (11.95 )

I don't recommend those shocks for the street through.

I was checking their catalog, how about their 3-way adjustable shocks? I'm looking for a good adjustable shock but I don't wanna pay the big bucks like those other two I mentioned.
