m_dennis...thank you....thank you!
I'm somewhat understanding that 19" fitment with RWS is wheel dependent. As in some 19's fit some do not due to how the inner barrel of the wheel is formed.

No problem. I had this set from the last car (991.2 base Carrera) so it needs to be done anyway.
19X11 O.Z. LEGGERA HLT BR RACE GR19X8.5 O.Z. LEGGERA HLT BR RACE GR
Seemed like the best value option from Tire Rack when I got them

Just a bump to see if anyone tracks there 991.2 and has experimented with lower control arms in front for added camber to use some r-comp track tires like Michelin Sport Cup 2 or the Dunlops or Trofeo?
Also anyone installed Giro Disc rotors that are 350mm all around and if so what pads did you end up using?

The 19" fit if you add a spacer. They had 14mm in stock and they seemed correct

I don't think 18s would fit. Here is a pic of the 19s pre spacer

they do fit but it rubbed as soon as it went over a drain in the shop

Yeah 100% it will depend on the wheel. Not sure how to tell without having a wheel to test with unfortunately

I would also suggest trying the Bridgestone RE-71R's. The track guys like them better than the MPSC2's ( stickier and cheaper). Plus there is the P zero corsa's that just came out ( and drop the ring time from 7:26 to 7:22).

arter, the RS71R are a street tire and the Michelin Sport Cup 2 are street but more like a R-Compound track tire....from what I am told and reading. Plus the B'Stone RE71-R doesn't come in 20" sizes I need I believe.

Tire rack has 295's in 20's so a little narrower than the 305's.
