I've had my Rota's on my RS for two years, with no problems not due to my stupidity (i.e. taking a 2nd gear corner at a roadcourse in 3rd gear, going off, then making a bee-line for the track curb head on at 30MPH). That resulted in some slightly bent wheels (2 of my four). Could of been much much much much worse.
I know that ROTA takes care of it's customers such as the one above, and as such I have my second set, this time some T-2's for the STi.
You can't expect a indestructable wheel for 650.00 per set, but in my experience they have been really reliable.
