Hitting the books to get a better angle on it
Got into the details some to see where it all leads. Camber, the tilt in (-) or out (+) of the tires at the top as compared to the bottom rim position. Our cars have a high amount of negative - camber and its wearing me and my slicks out.
WOrst its losing traction and killing my times on the track. GOtta Gotta stop the crap and get this working for once and all.
To compare our specs with our nearest neighbors the mustang cobra and corvette.
The specs I got show the solid axle mustang at -.5 degrees for the rear. [ Iam going for the low hanging fruit and doing the rear first to see if it helps and how much it does if it indeed works.] Front is harder to alter, ahh a challenge.
The corvette with an IRS rear is nominally at -.7 degrees. This is a good as a comparison and an interesting starting point . Our cars are set nominally to about -1.2 degrees and +/- 0,5 degrees.
I tested my RR wheel and had about 1/2" of camber clearance at the top of the wheel using a vertical level for measurment. After doing some preliminary realignment I ended with about 0.187" and about -0.6 degrees.
THat friends is pure dumb luck on the first try. I got between the stang and the Corvette, which is like our minimum spec setting according to the factory specs.
VIsually it is much more vertical after I drove it around to get the wheel to settle in before I remeasured it. My eyes are predijusted a bit and a camera does not show 3/8" reduction in TILT over the height of a 18 rim. I have 18's all way around so I can rotate them for wear.
I have to do the other (LR) and get it tested with both rear wheels set to a better camber angle. Ill keep yall informed as to the results and if it is functional without bad habits, let you know the results.
Enjoy, Woody

Hey Woody,
How did you adjust the rear camber being there is no camber adjustment on the rears. Have you installed a rear camber kit?

Re: Hitting the books to get a better angle on it
I redrilled the mounting holes in the frame on the inner end of the lower rear wheel strut.
Moving the arm inboard 0.1" was enough to fix one side, the other side took about 0.15". Remember this arm is about 4" off set from the center of the wheel giving you a bigger change than the 0.1" or so. Its like a 4 to 1 leverage due to its position which allows such a change with a little enlargement in the hole, sorta oval shaped.
Both of my rears are at 0.6 degrees of negative camber. This is not done yet as I have been alerted to check the toe in and toe out angle as causing the dreaded wear pattern on the inner edge of the tires. Iam going to see if I can measure the toe accurately, something more to do...................

Woody,
Did you see this post?

Speedybenz looks like they have a product that might help you out rather than tweaking the factory components.
Cheers,
