Default Quick offset question. Concerned about rubbing.

I was considering putting on some 17x7 wheels on my 03 wrx and was wondering if they would rub with the +38 offset. I'm lowered on prodrive springs if it makes a difference. Was just concerned if they will rub at all during normal driving and some lightly spirited cornering. Oh yeah, tire size is 215/45/17.

wagon or sedan? more chance for rubbing on the wagon

- 17x7 wheels vs. the usual 17x7.5
- 215/45x17 tires vs. the usual 225/45x17 although it does depend upon the tire - some are quite a bit wider than others of the same size
- Prodrive springs typically drop the rear only about 1/2", and the problem with rubbing is usually at the rear fender with low offset wheels.

con: ET38 is way less than the Subaru factory offset of ET55. Subaru performance wheel options are all ET53 for a reason - the closer you stay to factory offset the easier things are on your wheel bearings and steering components. ET48 is a very common choice close enough to factory offset to not cause problems - most aftermarket wheels for the Subaru are ET48 - and there are plenty of choices between ET48 and ET55. some other performance wheels specific to the STI run down to ET43 or so to help the wheel fit over the huge Brembo calipers.

ET38 is way too low in my opinion. You may not rub on a Prodrive lowered sedan - it will be close - but I would recommend trying to find a similar looking wheel in an ET48 or higher offset if I were you. If you want it to fit, plan on running as much static negative camber front and rear as you can with your alignment - you'll need camber bolts in the rear to adjust that. without a good alignment I think it will rub

If you have a wagon, well we've already seen major rubbing problems on a wagon with 17x7 ET35 wheels and those size tires. Customer thought he was getting ET48 and was shipped the wrong wheels by mistake. sad story - with a happy ending - here:
