spacers: Never

I would've liked less wheel gap, but at least I've got plenty of room for future coil-overs / lowering springs, and I got the perfect tire-flush, non-stretched, non-poked look I wanted, so I'm happy with it in the end.

I was a bit apprehensive about the +35 offset because I was nervous about chipping paint and other sorts of sheet metal screw-ups during the rolling process and when the rear tires were mounted, it did look like there was a *small* chance of rubbing the outer edge on the rear fenders; so I did what any other kind-hearted WRX owner would do - I watched the fitter do it to *somebody else's ride first* , then once I was convinced that the guy knew his stuff, I made sure that only he touched my ride!



There were still a few "Hail Mary" moments during the rolling process though. Strangely, it seemed much harder and took much longer on my WRX than it did on the other WRX (2011 / 2012 hatch)... don't know if it was just me or is the sheet metal on the 2006 harder / thicker than the 2011 / 2012?

I think it looks esp. cool at the front fender, but now the front wheels throw up all sorts of muck onto the front doors... will just wash more often if I can't get a nice flap to fit in there.

Special thanks to littlewhitewagon for advising against the 235/45R17 tire - I was still tempted and I did ask to see that tire size, but the words "fatty tires on narrow wheels" kept ringin' in my ears ... so not the "red bikinis & Baywatch" kind of sexy and too much "Mrs. Doubtfire" in that setup, so I dropped that idea in the end

17"x9"+35 would have probably bought the rims flush with the fenders too, but that would've slightly stretched the 225/45R17 tires and 235/40R17 tireswere not easy to find, so I went slightly conservative and settled on a 17"x8"+35 with 225/45R17 tires.

Will post my impressions on the tires once I break them in...

- T u r b o C -
I had 17x8+35 on my wagon as well, but it wastes a lot of room on the inboard which could be used to make more grip. But it is a good fit. Although you are flush right now, I would suggest you give the front a degree or so of negative camber. It will help the car turn in and feel better, as long as the tow is still set back to zero, there will be no tire wear issues.

245s will fit on a 7.5 inch wheel. i had 255s on my Mustangs 16x7.5s for the longest time. the issue i see is that tire is taller than factory size so it might rub.

Unless its dedicated autocross wheels, that's WAY too wide for those wheels. you really shouldn't be using anything wider than a 225/45 or so.

Sidewalls will be sloppy, and your response is garbage.

235 is also good for 7.5" wheels. It all depends on the sidewall height and actual tire. Sizes like 245/40R17 also is within safe limits of a 17x7.5 wheel, but the feeling will be a little more numb and will require a careful setup. If you are just driving straight, then get a narrower tire to save money in tires and fuel.

For example, on the Mustang, if you had 255s on a 16x7.5, I'm guessing the sidewalls were quite tall and they looked like little bubbles on those beach paddle crafts.

One week into the new set of tires and wheels, I'm quite happy with them, but I did notice slightly more roll than before. Maybe it is the offset (was +50, is now +35) acting like a longer lever and effectively "making the springs softer"? Or maybe the Potenzas have softer sidewalls. (or both!)

You're right, there's a fair bit of room on the inboard side, about 1.5" clearance between the inner edge of the wheel and the strut. I figure that this will give me more options when I upgrade the suspension and the "same as before" tire size will keep my fuel consumption the same or lower than before - might be lower because the new set seem to roll more freely. Maybe it's a different tire compound or maybe it is because the Rota Grids are significantly lighter that the Legacy GT wheels that were on before the upgrade.

So far, I haven't had the opportunity to really challenge the tires, so I'm not sure whether I "need" that potential extra half inch. I suspect that the increased body roll I'm seeing will play spoilsport way before the tires break traction though.

I ran 255/50/16s on the rear and 245/50/16 on the front for autocross on a car that had way too much power for autocross. it wasn't sloppy at all. it was a track car with a license plate on it basically.

Again, as I've stated in several posts - your experience with other cars means **** for subarus. What works for them, not so much or us.

And again, autocross people do retarded things that have no bearing on anything outside of driving around cones.

You have a wider track and more grip, you will get more roll... it's physics. The fuel consumption might go up or down, friction versus weight savings.

I have an 07 sti. I just bought the 11 sti bbs's that are 18x8.5 +55. I have not purchased tires and I'm not exactly sure how this set up is gonna fit. I'm considering two different tires, a 225/40 and a 245/40. I'm surfing and searching looking at pics and whatnot but I found this thread. My real question is am I going to have to run spacers to get that desired flushness. I'm thinking 20mm's because that will put me at a nice +35. I have two different 25mm spacers I could buy right now I just don't want to get them and have to run crazzzzzzy camber. I have camber plates in the front, and will buy them for the rear eventually. I just want my car to look sexy with these because I think theyre beautiful wheels and I like the idea of keeping it factory. Does anyone have any imput?

Well that would depend on my tire size. If its the 225 it will stretch a bit more so the rim. 245 will be meatier so then the tire

Thanks btw I hit him up

year: 2005
model: WRX
wheel model: TSW TrackStar 5
wheel size/offset: 18x8 +50
tire brand/model: ???? Undecided
tire size: 245 or 255
suspension: BC coilovers
alignment: 1.7-2 front 1-1.2 rear
spacers: depending on fitment

Looking to be flush(tire or rim) with a minor roll if necessary... It is mainly a street car so no big drop just a nice suttle stance is all I'm looking for

Want a 245/255 tire (will settle for a 236 if I have to)so if I have to space it out with 10-12mm spacers that fine just looking for advice to see what ill need

i am saying that a tire size will fit on a wheel, not that it will work. claiming a tire wont fit because you wouldn't put it on is like saying don't eat oranges simply because you don't like them. my experience with cars started 20 years ago at a race track, i have seen almost everything. stretching a tire across a wheel that is too wide only hurts every aspect of performance and tire wear. if a fat tire on a slightly narrower wheel hurt performance and safety then Formula 1, NASCAR, Indy, and Le Mans series wouldn't allow it to be done.

You'll need a rear roll at the least and with that high of an offset I'd venture to say you might run into strut clearance issues.

No he has plates and possibly camber bolts as well.

For that fitment you cannot get enough camber out of bolts alone.

Do you know what kind of plates he has? I need some that will fit on my Megan tracks.

A 255 or 265 would be easier, but again - with aggressive camber is be curious to see inboard clearance on 275's.

I ran 17x9 +44 with 255/40's neova ad08's on a 07 wrx sedan on tein coilovers it was kindof low and it shaved a huge cut in my rear tires against the suspension. But it was fine with a 5mm spacers

Depends on ride height but if you already have the rear rolled you should be fine.
