I'm trying to get my M6 SS to hook as best as it can on the street while keeping the stock springs n shocks. My first step is a panhard rod and lower control arms, but I'm ignorant to the adjust. vs non-adjust. debate......does anyone have any input for me? What other suspension parts would make a considerable difference that are worth the cash?

 

The adjustability is key for when you lower the car. When the car is lower, the rear end becomes more off-center, and may cause you rubbing issues. With an adj. phr, you can re-center the rear end and cure most of the rubbing issues.

What are you going to do with the car? Drag Racing? Autocrossing? Or more of a boulevard cruiser/daily driver?

 

It's a second car, but it'll be used all around, highway trips/drive to work on a sunny day/occassional weekend street car.

 

Panhard will do zero for hook, it's only working in the
corners. LCAs, maybe a little. Tires, a whole lot.
LCA relocation brackets, a good bit. Torque arm,
depends on the geometry I guess, probably some
bite to be gained.

 

go with adj. PH if you plan to lower your car or plan to go with 315s tires out back.
panhard stops fish-tailing
LCAs stop wheel hop

 

and adj. LCAs are not needed, non adj. ones will do the trick
