Oh, btw, I highly recommend swaybars.
I changed from Koni's with HR green springs 9standard sport spring) to HR 965 (964 turbo) sport springs which are another 50% stiffer and went to a 24mm front and 22mm rear adjustable sway bar and instantly gained 3 seconds a lap at Phillip Island International circuit in Australia. The difference in handling was phenomenal with the car feeling so much more planted and responsive. This track has a lot of 180km/h plus corners and the car just gave you so much more confidence as it wasn't moving around anywhere near as much.

 

Can anyone tell me what the widest tire in can install on the rear of a Porsche 993 widebody with a 17" x8.5 rim
tks

 

I am running 215/45ZR17 in the front and 275/40ZR17 on the back on the stock 17" Cup wheels and I love it. No need for any modifications in the back.
The car is Carrera 2 and I do nor need to run spacers in the back.

 

I was wrong about no problems 275 tires in the back! Unless I mount a spacer the right tire will ocasionally scrape on the oil line and the control arm. Going back to 255!
