New track setup for 200TW classes

Well guys as some of you aware I mostly run MICHELIN Slicks on track days but both SCCA and APEX HPDE have some VERY competitive 200TW classes that I want to run in.

After some surveying of the guys that run that class ALOT the current feedback I got was that FALKEN AZENIS RT660 seem to be the flavor of the month so what you see in the pics below is what I will be running.

Now I have NEVER thought much about running a tire that had any tire poke especially for daily driving but since I will run this setup on the track only; then I compromised a little on that on the REAR wheels.

I run APEX 18 x 11 ET25 BMW spec wheels ALL the way around and I have mounted on them 315 30 18 RT660's. There is NO tire poke at the TOP of the wheel well on the FRONTS because I am running -3.7 CAMBER. On the rears it looks like I have MAYBE 5-10MM tire poke at top of wheel well. I DO RUN a 5MM spacer on the fronts. Rear camber is -2.7.

The GOOD NEWS is that since these tires have ROUNDED edges instead of a squared off edge like my slicks do then you have a little more room. Technically if the rears had ET35 instead of ET25 than THAT would eliminate the tire poke.

My next competitive event is april 9th at MSR on the 3.1 with the APEX LAP ATTACK folks so I will let you know how these perform.
