NXI,

Your setup is very similar to mine, I run different dampers, JRZ, and spring rates but the rest is there or there abouts.

I find mine fairly neutral, granted I do not have the tracktime you do, there is hint of under steer but I feel I can dial this out by adding a little more rubber at front.


I run 245 section rubber which cures the understeer at the expense of some arch rubbing.

That is the very direction I am planning on going Thumb

What profile and diameter do you run?

Mines a 996, so I run 18's, Cup 2's come in a 245x35 which I was considering to elevate some of the rubbing, as oppose to a 245x40 although in honesty the rubbing is not really a huge concern, worst case I will eventually need a new arch liner.

Apparently the Cup Arch liners have a slightly different shape which helps Question

Digger, I run a huge Halfords Ripspeed Wing Grin

I use 245/40x18 on a 9" rim & 245/35x19 on an 8.5" rim

They have roughly the same amount of rubbing since it's really only with some lock on. Big compressions with a bit of lock such as Eau Rouge & the Foxhole is where you really notice it.
