Default 17x9 +30 offset on a wagon?

Im looking at a set of torque r in hyperblack for my 02 wrx wagon, will a 17x9 with +30 offset fit? of course I plan on rolling the fenders and running about -1.5 camber on all 4 corners.
thanks,
Nate

It's going to be close and pretty hard to fit. Alot of camber, rolling, maybe pulling, the right tire size (some 235's run chunky)...

thanks grippy, and I got your PM response. Ya I knew it would be difficult to fit it, im thinking falken azenis for the tires, but any other tire recommendations? how much camber, more like -2.0? i dont want too much camber because i cant afford to replace tires every few thousand miles!

oh yeah, and i will be using BC racing inverted strut coilovers

tire wear and negative camber is a myth.

its about toe in/out

^ 18x9.5 +35 has already been done... which has more overall track that a 17x9 +30... it can be done

just not easily

My experiences say otherwise. I was running 0 toe and about 2 degrees negative camber. The inside of my tires wore out before the outside. It probably depends on the tire. More toe just makes it worse.

^ the wear will show wherever the tire is touching the ground... if the toe is bad it's going to wear on the inside or the out or evenly... where it touches the ground. Camber only makes slight difference in wear... toe is where it's at.

-2 isn't much btw

your toe was NOT '0'

2 of camber is NOTHING

I was there when the alignment was preformed. It read 0 on both sides on the computer. I guess there is a good chance that the rack was off, but regardless, camber alone does cause uneven wear. I am not saying that my inside was destroyed before there was any wear on the outside. There was somewhere around 2/32 to 3/32 difference from inside to outside after about 12,000 miles most of which were on the interstate.

Tire wear is cause by friction with the road. There are two types of friction effecting tires. There is rolling resistance and regular old dragging friction like pulling sandpaper across wood. If a car had some toe you are adding a component of regular dragging friction. That is why toe causes tire wear. You can avoid this component of friction by having 0 toe. The rolling resistance part is unavoidable with alignment techniques. The rolling resistance or friction is highest in the area of the tire that has the most pressure on it. That is why race teams measure tire time across a tire. To figure out where the most pressure is. Think about it, if there is more pressure on the inside of the tire that area will be hotter (more friction) and it will wear faster than the outside. When driving in a strait line with negative camber, the outside of the tire has less pressure on it and therefore less friction and slower wear. The inside has more pressure therefore more fiction and quicker wear. Camber should be adjusted based on driving habit. If you drive hard around lots of corners or storm on and off freeway exits 4 or 5 times a day (more pressure on the outside edge of the outside tire) and are running stock camber, even with 0 toe the outside of your tires will wear faster than the inside. If you drive mostly interstate like me and have more camber than stock even with 0 toe your inside will wear faster. Yes toe has the most effect on tire wear but, to say that camber alone doesn't cause any uneven tire wear is wrong. You are going against physics by saying camber wear is a myth.

If you still don't believe me, how do tires on motorcycles wear? It's pretty obvious that they have 0 toe. Why do people who putt around town all day on race tires wear the center out of their tires quicker than the outside?

that is gotta be it


and regardless of the rest of your post....which is pretty meaningless....it is not possible to get your tires to wear out with 2 of camber unless you drive nothing but straight lines

this comes up here all the time.....any time you corner in these cars, you loose camber and with -2 that makes about nothing in a corner

I run almost -3F/-1.8R and the last set of tires i took off was even all the way across....at the wear bars...and ~22k miles on the tires

and i DO run a bit of toe out in back


so saying that camber will eat tires is just not a very usual thing with subarus as it isnt easy to get enough to do it unless you TRY

thanks for the responses guys. I dont want to have super agressive camber just to get the wheels to fit, Im in Utah so im gonna be going over plenty of bumps in the roads and I dont want to rub everytime. maybe I should consider a bit higher offset, like 35-38?

^ 38 is a good option... you can get by with just rolling the rears with 255 width tires
