Wheel fitment

New to subarus but was wondering what wheel size would i be able to run on my 2007 wrx wagon without any rubbing? It is lowered by previous owner.

this is your best options for 02-07 WRX>

you might need to roll your fenders a wee bit to get them to fit since your car is lowered by the previous owner.

I'd go 225/40R17 as you won't need to do fender work or use much camber, the wagons are much more narrow and the rear proves it with wide wheel/tire combos. 235/40R17 will work, but you'll need camber and fender work to not rub on a GG wagon. Note that 215/45R17 is the OEM tire size for the OEM 17x7 wheels, add another inch of width and you'll need to lower your sidewall a touch, thus the 225 or 235/40R17.

Also keeping the wheel offset close to OE as possible is very important. The factory wagon offset for the 16x6.5 paired with a 205/55R17 is +52-55, therefore when going wider you'll need to lower that offset 5-10 (10 at most) for every extra inch of wheel width to aid against rubbing (spring/spring perch/fender)...so for a 17x8 +45-48 would be ideal.

My 02 wagon has 17x7 +48 wheels from the BRZ, and they don't rub everrrr. I don't have any camber adjustments differing from the 16s and I'm stock height, this setup still leaves enough room for 17x8 if I use some negative camber (~ -1degree) as I can still fit 1.5-2 fingers

I swear he said sedan. My recommendation is too wide for a wagon. I'd agree with RoboTuner for an 07 lowered wagon. 235 is difficult.

+38 is the max you can go in a stock wagon if using stock 6.5" wide wheels. not that you would have +38 offset on a 6.5" wheel, but hey, whatever floats your boat. from there, math can tell you what will fit.

you can plug you OE spec into this calculator and really dial in your choices: https://www.wheel-size.com/calc/?whe...=30mm&scl=51mm

not knowing exactly how much your car is lowered from the previous owner might make things a bit difficult.

if you stay wagon width, watch out for too much camber as you can then start to hit your strut tower. also, if you go to a 8" wide tire, do not stay oem offset. you will want +50 at a minimum but +48-46 would be ideal. +55 in pretty sure will make contact with your strut tower. alot of people forgot about the inside clearance as well when fitting wheels & tires.
