Has anyone ran 18's on an F-sport?
Do the AWD base and F-sport's have the same rotors/calipers?
If 18's will fit on the F-sport no issue, what about when lowered with RSR regular downs? And if so, can you post your wheel and tire specs?
Thanks

The AWD F-Sports and non-F sport AWD models come with the same brakes/caliper/rotors.. 18s will certainly fit the AWD F-sport without a problem. 18s may be a problem only on RWD F-Sport models that have the bigger brakes/rotors up front.
I'm not sure about any issues with RSR-Downs and wheel sizes (i've never lowered any of my cars b/c I live in NYC and have dealt with too many wheel/tire/suspension issues with the crappy roads).

Great info. I wonder if they are interchangeable?
The standard brakes on the non F-sport have excellent bite! Here's the info provided by Lexus for the 4GS:

What tire size is everyone using? It looks like a toss up between 245/45/18 (+6mm diameter), 255/45/18 (+16mm diameter) and 255/40/18 (-10mm diameter) ... I'd rather the 45 series if there is no rubbing issues?
