fitment will not be an issue. is350 can use 17" rims (no less) and still clear the brakes, however i personally recommend you NOT to put 350 brakes on a 250. 250awd ABS settings aren't the same as 350's thus your ABS with these brakes will get confused during heavy braking and possibly increase your stopping distance due to timing issues. plus the price for these brakes aren't cheap. you're much better off saving up a bit for the f-sport brakes or go for good aftermarket brakes. but if you MUST they'll fit.

ahh it'd be a similar issue but not exactly. from what i can remember, f-sport brakes are almost 14" where as the 350 brakes were i believe 12-13"and where 250 brakes are about 11-12" (front brake size wise). That said, the 350 brakes will JUST FIT in the 17" rims and the f-sport brakes in the 18" rims. so similar issue but not exactly if you know what i mean ;p

I think what he means is that if the ABS settings are different from the 250 AWD to the 350 then isn't it possible that the ABS settings are different from the 250 AWD to the ISF? Therefore couldn't the F-Sport brakes have the same potential problems?
Anyways, my *opinion* that the FSport will work fine (FSport brakes have different part numbers for the 350 and 250... I don't know what's different there...) As for the 350 brakes... I'm sure there are people who have done the swap... any IS250 owners with the 350 (or F-Sport) swap care to ring in?
