Wondering who in the group has experience with the best setup for street and track. I do 3-4 DE's per year, stock suspension, separate track and street wheels/tires. Most street driving is for fun, fairly agressive. Not many long trips.

I have searched and found what I think are some good recommendations.

The facts:

Tire wear on old street tires:
-Fronts both have wear down to the cord on outside corners, otherwise wear is just short of wear indicator evenly across tire. Both fronts visually have the same wear.
-Rears are perfectly even wear, nearly down to slicks
-Current alignment, everything very close to spec except front camber +.6 left, +.2 right (spec is roughly 0).

I understand from searching that -1.0 to -1.4 is max stock adjustment for camber.

I think the major adjustment I need is just extra negative camber, but how much?
a. Just align back to stock 0 camber?
b. Move to -.3 to -.5 camber
c. Go to near max camber -1.0 or so?

Any experience appreciated.

 

Hi Dave. Suspension matters but i am assuming yuo are stock or with a few upgrades. My .02 is try this either way...

Front camber max negative with what you have
Front toe 0.0 or slightly toe'd in

Rear Camber -1.5 to 1.8
Rear toe .25 to .28 in

If you have the print out form the car now i can tell you what you will feel.

 

I will attempt to attach the printouts showing an example of a before and after from a Porsche dealer. I had previously asked them to set front camber at -1.0 to -1.1 but after seeing the +.6 on one side of the front they decided to adjust back to the 0 stock setting.

Hopefully the printout is helpful for future reference for all to more fully understand.

 

Here's my alignment printout.

 

+1. Do exactly as Sam states above. That is about all you can do with a stock suspension. Have your shop crank in as much neg. front camber as your front shock towers will allow. Run just a little bit of front toe. +06' total toe works well. With the rubber bushings in the factory suspension, your front will naturally toe out in the front under braking. I like +17minutes per side in the rear for toe, +26' to +34' total rear toe.

 

Looks like before was a total grandma alignment. I see it looks like stock height. Does it feel better? It could be that that is all they can get as far as aggressive goes because it's not much diff. Just more even. See if you can ask the tech if he maxed out the negative in front. That will do the most for you. Feel free to reach out if you need help.

 

Thanks gentlemen for the advice and assistance!

The suspension is stock.

Car feels better on the street with the new alignment. This was my first alignment since owning the car, and I am not sure how it could have got out with so much positive camber unless aligned poorly in a previous service . I will be at Barber Motorsports this weekend, I expect it will feel much better there also.

Considering the excessive outside front tire wear on the old tires, I am trying to decide the sweet spot for both drivability and to even out the tire wear. I am trying not to go so negative that I now get bad wear on the insides of the fronts.

I am hearing recommendations to go to max negative adjustment which agrees with previous research. The porsche service guy thought going to -1.0 would create a bad situation with inner tire wear.

Does anyone have direct experience with the max negative camber that can likely be adjusted with stock suspension?

 

If you're not at the track, anything past -1.5 in the rear is going to start causing premature tire wear.
