How to stage purchases for traction enhancing products I put in a new clutch and Stage II heads and I have lost all my traction under acceleration. I am breaking in the clutch so I have not dumped the clutch. Everything I have been doing is to get tuning data right now.
When I punch it while rolling in 1st or 2nd the tires break loose quite a bit. I have 315s on the back with 17 rims. The suspension is a relatively new SLP Level 1. I couldn't go lower because of my SLP LT. The Level 1 comes with reinforced PH bar and LCA with Poly bushing. I don't seem to have wheel hop.
I am not sure what I need to be getting and I can't get it all at once. So, I want to stage my pruchases.
I want traction for drag racing. I will be putting nitrous on soon. I imagine I need a new torque arm. Not sure if LCA lowering brackets will help, new LCA, PH bar or what. The SLP LCA seem to work well and I never experience binding or wheel hop. I realize that these rims and tires aren't helping. I will go to 315 Drag Radials next summer.
Any suggestions are appreciated.

Re: How to stage purchases for traction enhancing products FlamnTA- if your car has been lowered at all, you need to lower the rear end of the LCA's with some relocation brackets. At the very least you want the LCA's to be level with the ground while the car is at rest and the suspension is loaded (read: not supported by the frame on a lift or jackstands). Even better than that (for straight-line traction) would be having the rear end of the LCA slightly lower than the front (again, relocation brackets are the answer).
Second recommended part is LCA's with a spherical bearing at at least one end, if not both. You won't really feel the bind that results from poly/poly units, it will just seem as if the car is tail-happy (read: the car will tend to oversteer).
If you feel that you MUST do something with the torque arm, save up and do it right the first time. IMO, a polyurethane front mount is worthless as the factory arm is pretty flimsy; by eliminating (well, reducing) deflection at the mount, you're just going to end up with deflection in the only other possible place- the arm its self. Besides, the poly front torque arm mount is another possibility for bind when you're in the twisties. There are plenty of aftermarket torque arms out there, so do your research; myself, I really like the LG arm, but most (if not all) of the other arms have their supporters as well.
But when it comes down to it you're putting 400+ hp to the wheels, and it's a lot to ask of any suspension/tire to plant all of that power. Assuming that you don't want to go to a drag-type suspension (read: lots of fun when it's time to go, but not so fun when it's time to turn or stop), you're just going to have to modify your driving technique to the available traction.
Just my $.02...

Re: How to stage purchases for traction enhancing products Excellent reply! All makes sense. Especially the last paragraph. Oh, if I could only be an autocrosser or dragster at a flip of a switch <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
