Upgrade Control Arms

[pontiacgp]

adjustable uppers let you set your pinion angle....some people mistakenly think a pinion angle can give you better traction..

lol, I resemble that statement
from my new understanding... a good pinion angle for drag racing is -2 degrees. For street use is 0 degrees.
It won't necessarily help with traction, but it will improve vibration.

for traction, you need to adjust the instant center of the suspension, to improve launching inertia. You can do this with relocated control arms. They come with brackets that you weld to where your lower control arms bolt at the shock mount, and move the bolting location of the LCA lower.

wheel hop is caused from play or flex in the suspension, and it can be improved by stiffening your control arms by boxing them or buying quality boxed/tubed control arms. The control arms in my GP are boxed, and this is why I imagine there is zero wheel hop.

I went with the adjustable uppers and boxed lowers and I have no wheel hop at all now....I went with UMI Performance....http://www.umiperformance.com/catalog/i ... mgkluep2f0

The link I posted Jbreau are for UMI control arms. I may just go with upgraded uppers, but non adjustables then if they're not controlling the wheel hop. It only hops sometimes, not all the time.

Someone I told me before that the adjustable uppers helped control wheel hop, hence why I asked.
