Need some Chassis Suggestions

[Dave Steltz]

Got my car back on the track (after a wreck last year) this weekend and had some issues..

Made 6 passes total (between sat and sun), all in the right lane...I know the track was fine for 5 of them, as other cars just as fast or faster than mine had no issues..

About 250-300 feet into the run, on 3 of the 5 runs, the rear came out from under the car, and kicked to the right, which made the car go left...

Today the first run was 8.76, with a 1.231 60 ft and went straight down...Second run same 60' (1.232) and not much after the 1-2 shift the rear got lost and had to abort...Third run same 60 again (1.231) and it got loose , but not as bad, and then went down the track..
After the 330 or so it on rails..

So I dont think its the alignment or anything, and its pretty much ok at the launch, but not in control at all at 300 feet...

One thing I'm not sure of , is where the pre-load is, when I had it on the alignment machine I moved the rear a small amout, (it was a little cocked) and I'm not sure that I reset the pre-load to where it was..

So any and all suggestions are welcome...
