Maximum Motorsports - without a doubt.
tip - don't be dup'd by cheaper stuff that says they're comparable.
They are not.
Griggs is comparable, but harsher and more hardcore track,
Some steeda stuff is good, but not all.
don't waste your time and money like I did -
MM all the way.
They engineers and test's they're stuff. It really works well.
My suspension stuff is listed in my sig.
If you have any questions I"d be happy to explain,
I just replaced my whole setup over the winter. a bunch of research was involved.
To answer your question:
I recommend good strut's and shocks,
MM coil overs, and CC plates,
LCA's, (lower control arms) - leave the stock uppers in !!!
XL subframes,
and Panhard rod.
That will give you a good all around performance advantage on the track, and still ride smooth and quiet on the road.
It will Reduce wheel hop, and axle wind up, and will corner like a bitch on wheels,
Improve traction at a launch and out of turns.
They have some box kits, or you can piece it together.
Good luck.
Also, Despiet my good intensions - don't just believe what I say, read up on it on they're site, or call them with questions.
