track wheels for boxster s (2001)
What's the recommended setup for track wheels? Would like to run 17's or 81's but want a "square" set up-- same size wheels & tires front & back so can rotate and manage tire wear. Does anyone do this this? what sizes wheels tres should I be running?
Did a search-- couldn't find much on the forum on this

Ha, indeed.
I've heard of guys running 9's and 10's. 9 x 18 front (OEM boxster rear)and 10 x 18 rear (911 rear), so clearly 9's will fit up front, though you'd then be looking at 245 or 255 squared up on 17 or 18 x 9 all the way around. 255's would be a tight fit up front- though I've heard of guys running 255's with rolled fenders.
I'm a PCA instructor and I LOVE a neutral to OS balance, which is what I have with a 30 mm split on my '03 S. I wouldn't want a square set-up for some high speed tracks. But to each their own- good luck!

I have run nearly a square set-up before, with 255/35-18 front and 265/35-18 rear.
This is not a bad "band-aid" for having insufficient front camber, but if you get camber plates or GT3 arms and optimize front camber, then you really need about 30-40 mm stagger front to rear. There is a lot more weight outback, and it is best to maintain about the same weight/mm of tire width front and rear, all other things being equal (which they are not until you fix the front camber deficiency on these cars).
Good luck.

Almost all of us spec boxster guys run a square setup on 17s with 255 40 r17s.
You have to roll the front fender a little and run a 5 to 7mm spacer. If you don't run the GT3 control arms up front to move the wheel position back slightly, you will rub on the inner fender liner.

OZ Allegerita are lightweight and inexpensive. 18" will allow you to run a little bit wider tires than are available in 17", and thus your better choice for performance, but 17" tires are a lot cheaper.
Knowing my next set of 987.2S tires will cost $1200 makes me pause a lot more than $600 tires for my 986S did. You can do a lot of tuning with swaybar and alignment, too. Camber plates to increase front group would help more than reducing tire width for less grip in the rear. I found my 986S with a GT3 swaybar (and no camber plates) pushed mildly at autocross, but was very neutrally balanced on the track when turn radii and resultant rear slip angles were much higher.
