Porsche rear camber settings

[jwilbur1]

Has anyone experimented with less negative camber for the rear tires? It sounds like rear tires routinely wear out on the inside edges on 996's after 10,000 miles. Is Porsche just trying to protect the owners from oversteer?

You can so it, but it will effect the handling of the car in corners. If you do alot of track or driving that includes alot of corners, the stock setup is the best comprimise. You need a negatice camber when corering so the ousde of the tires do not wear out. When cornering, the outide tire should be flat agains the road surface. Last time I checked, my camber settings were -1.04 and -0.96.

So you don't think Porsche has more negative camber dialed in than needed for the tire to corner at it's maximum potential? The reason I ask is I could see them doing that if it reduced the car's tendency to oversteer. If the Porsche values optimize the cornering, then that's what I want! :cheers:

Decreasing the camber will increase oversteer. You can balance that out to some degree by going with wide tires and a liitle more pressure or increase the understeer at the same time. For some one driving their car in a spirited way, but not taking it to the extreme on corners, I suspect that you could reduce the negative camber substantially without any noticable effect on handling. This would also greatly increase the life of the rear tires which now last approxiamtely 10,000 miles because of the camber setting causing the inside half oif the tires to wear faster.

Most of my driving is high speed but light cornering and I may try cutting the camber in half next time I replace all 4 tires to see how the tire life increaese. However, if I was younger and more crazy with my driving, I would keep it stock for a little bit of safety.
