I have an '02 z/28 that I race in a quite a few unprepped track events and what not. I'm curious what are the guys that are racing in unprepped events an street racing doing on the suspension to get it to bite more. I can go to any regular prepped track and 1.44 60' off of the trailer, but these unprepped surfaces it MIGHT 1.7-1.8 if I'm lucky. Usually I lay out vht if allowed or pimp juice also. Suspension is as follows on a 275/60/15 Mickey pro radial:

Umi tubular tunnel mount torque arm (adj)
Umi tubular control arms (single adj)
Umi tubular panhard bar (single adj)
Umi tubular sub frame connectors
Bmr 1" lowering springs
Spohn drag sway bar
QA1's 12 way adj on all four corners with drag springs up front

unless your driving around with those QA1's on 0 rebound and compression on 12 it would be hard to hook on a un-level surface.

Do you have LCA relocation brackets? They can be set to the lowest position to put the most downward force on the tire and help it dig in on low traction surfaces. Especially since your car is lowered.

This. I think my lca relo brackets made more difference than any of the other suspension stuff I did when it comes to traction. I'm at the point where if one doesn't know where to start with suspension mods that I'll tell them to get the brackets first.

I recommend them to everyone as a good starting point. Even stock height cars. You would be amazed at the number of people who still don't believe in them and insist you don't need them. There is a reason we make them.

Why do you want them in the lowest hole? Shouldn't they be in the lowest hole possibly while keeping the parallel with the car and not arching downwards? Just curious.

This is a diagram we like to use to help show people why we suggest this:

Heavy H.P.

Help me understand how this works for stock height cars? I might be lost.

As the axle tries to wrap under load, the lower control arm being at a downward angle will now be lifting against the weight of the vehicle which will essentially drive the tries into the pavement. If the arm is straight or running upward, it will actually unload weight from the rear of the car and cause wheel hop. This geometry works the same no matter if the car is lowered or stock height.

This helps me out a lot, braidington never preps the track on a street heat night so the next even I should hook up better now. What about the ta? Can I adjust that too to help hook on unpreped track?

Will those bolt on brackets work for stock Lca's? That's interesting indeed. I just now started hearing a lot about squat/anti squat
