For autox I would suggest 18" wheels so that you can get the widest rear tire possible without losing sidewall stiffness. And you won't need to change sway bars. The car will have understeer, but I find that more useable than losing the back end. A lot will depend on how you drive the car.

RE-71's are terrific. You can flip the tires on the rim once the outer shoulder wears. I got over 100 runs from the fronts (50 before flipping). Rear outer shoulder is now spent, but I can flip and have enough tread for another season. The car has mild camber with 2*F/2.2*R because it sees a lot of commuter time too.

I personally prefer oversteer to understeer. At least you can rotate the car. With a stock suspension, yea, the Boxster is a great handling car, but the difference is dramatic with mods and the right alignment. It goes from great to super-duper

Yea, you go from a stock class to a points based class. In theory you are classed with cars that have similar performance. At the end of the day, it all comes down to the driver.

Putting GT3 control arms would also put you into a point based class. Yes you do get a lot more camber. You really need to look at the entire suspension together as a system.

I humbly disagree that 18's are better for AX. I suppose the slightly shorter sidewall may make a slight difference, but you will be paying a lot more for tires. I would go with 17's and save the $$
