My car is a 98 Camaro A4 4400 stall, full suspension all motor, ET streets, ~3100lbs, ~400HP.
When its cold outside, for some reason I am spinning at the 330ft mark. When it spins, it spins, grabs, spins, grabs, spins, grabs and then goes on. It is hooking great off the line. It pulles the wheels a little and 60fts 1.4-1.5 with no spin.
What could I do to fix this?

Usually there is more rubber built up on the starting line (if lots of slick tire cars run) so you will hook good off the line. My Red car on 325/50 MT radials would hook good off the line but then about 100' out it would spin/tire shake like your talking about, when it went into 2nd gear.
When using a built 4L60, 1st gear is real low so it hits real hard but then it shifts into 2nd gear real soon off the line. Many times the track is not as sticky at that point as the line is. If you play with tire pressure and shock settings it will help. I went harder on the rear shocks and softer on the front shocks to help weight transfer and it worked better, also added 1 psi on tire pressure. I now have switched to MT 28/10.5 W slicks for index /bracket racing and the car hooks much more consistantly then on the 325/50 radials.

The next time the track was getting a lot of leaky cars on it and I can see why it might of had the problem, but this last time there were not too many leaking cars and the track was prepped good and others with simular setups were doing fine.
I don't think track prep is the problem really. I could see leaky cars causing problems. The track crew have been letting people run with leaks here lately. There was one car leaking and I heard the track guy say well its not leaking too bad.
I was thinking it was my car because of the new setup, but I guess the track could be causing it too.
So in that case for bracket racing what would you do? go with bigger tires?

With an auto car thats strange. You shouldnt have the hp to spin that far out on even a halfass track. Soften the rear shocks, lower tire pressure, and tighten the control arms....... Are they putting down any VHT?

Next time you head out to your local track,get there early and watch how far down they are spraying VHT.Ill bet they are only spraying too the 330 ft mark,and thats why your breaking loose.Or they are not spraying at all.We always walk the track before they start,and check it over and talk to the crew.
