cereal - a +45mm offset should be fine on a sedan, pushing it on a wagon. Also what zahnster stated, type of tire used, even in the same size for all brands, will vary among manufacturers. Example: Azenis Sports are generally wider than the same size from another tire co.

thanks G-force, but i was not really worried about rubbing, i am worried about long term problems that may come up with my wheel bearings. However giving the way you answered the question, it seems like i souldnt have a problem in that area either. would i have any wheel bearing problems down the road?

If we wanted to use 285's on our cars (like the Cobb Tuning WRX), then the offset would be around +35?

How about 18x8 +42? It's so close! Where would this cause problems on an 02 WRX? Very helpful thread!

It will put uneven load on your hubs and bearings (and will probably rub on the fenders). -Josh |

I would like to add that the listed offsets don't apply neatly to Foresters since they require a slightly lower offset from what I've seen in the Forester forum. The OE 16x6.5 are ET48 IIRC. There have been instances of P7s (17x7 ET48) not fitting. AG May the GT-B with you! |

1st of all you need 10" wide rims yeah i think that offset would be apropriate maybe even +28-30 but your biggest hurdle is huge fender flares take a close look at conebasher and youll see what i mean mike |

alright i cant make sense of any of this.. all i want is a YES Or NO answer. and no smart comments about how i shoulda read this or that. Will Motegi MR7 18x7.5 with an offset of +45mm do damage to my99 2.5RS GC8 now i know that it will fit and i know that youve all said what fits is not neccisarily what is right for the car.. so just tell me if its going to be majorly haphazard to my GC8 or if i can get away with running them.. thanks.

calworld - yes, that would perfectly fit - but don't forget about tire sizes as well especially if you have a wagon or a gc8. I have those exact specs on my Volk Racing GT-C's. I've got a WRX sedan btw. Macncheese - what wheels are those? |

Will an ADR wheel 17X7.0 with a +43 be ok, just barely? Thanks!

I haven't ever seen any threads on wheel bearing failures, but it does make sense that numerically small offsets would increase bearing problems over time. Cornering hard should also be avoided...hahaha.
moving on... I'm not a suspension guru, but I think something is being overlooked. I think you'd call it torque steer, but I'm not sure if that is the *real* name. Let's assume that a USDM WRX sedan can fit 245's all around with ZERO offset for a moment. I know this is fantasyland, but bear with me. In the front, stepping on the gas will toe the wheels inward. It will also lift them up slightly, depending on caster. They will also creep forward of their normal location. Slamming on the brakes will toe the wheels out greatly. Since the WRX tends to dive, the toe out will be extreme. The extra offset will give the tire more leverage to move around in the bushings. It will also give the tire more leverage to steer. If you press on the gas pedal when exiting a corner, the outside front tire will steer INTO the curve. Since the car is leaning during a corner, the tire will climb forward and UP! This is extra understeer that an AWD doesn't need. Like I said, I'm no expert (I probably got parts wrong), but my point is that all kinds of wacky suspension gremlins are waiting to pounce on "wider is more gooder" guys. |

"some place" is telling me that a Motegi MR7 in 17x7 +40 will be okay for my car. Her distributor says that it should be okay, but I don't think it will be okay, and told her to hold off on ordering those until I can get a clear answer from someone, yay or nay. I don't plan on buying tires from them. The woman behind the counter seems to think that the rims can be mounted on the hub without a tire and we'd be able to tell if there will be rubbing issues. I'm not real confident in her at this point, and 'guessing' isn't the right answer for me. I'm riding on Eibach Pro-Kit springs, btw. Maxx |

Did you guys totally misread the first post? Nowhere in that post did it mention +40mm offset as being acceptable.

yes, I read it... and that's what I was arguing with this woman about. She was convinced that a 17x7 +40 would fit, and I was trying to tell her that it wouldn't.
So she was telling me that I was wrong, and I guess I had to come here to get that 2nd opinion (again). -Maxx |

You are right, and the original poster is wrong: the wider the wheel, the less positive offset required to stay within manufacturer's track. FYI Last edited by FYI; 06-10-2003 at 08:48 PM. |

OK, How does the Jun Hyper Lemon WRX fit 18x9.5 Advan RG rims with 265/35R18's in the fenders? I don't know the offset sorry. I'm not sayin I want to put something this huge on my car, but it only has a 2 inch drop (my car) and I would love some 18x8's with a nice lip, so around a 40 offset>? Thanks guys, this is a very helpfull thread by the way.

Short answer: IT'S A FRICKIN' JUN!!!
Long answer: It uses every trick in the book and a few that aren't. The Jun car is converted to 5x114.3mm bolt spacing (front only, I think). I haven't looked at it in a while, but I'm sure that the fenders have been changed, rolled, massaged or altered. Different wheels and tires can be used front or rear, as long as the diameter remains close to the same. I'm sure that the coilovers and camber plates are designed to fit a wider tire. Another possible way to make room would be with wagon L arms. Jun could have even moved the supsension pickups a centimeter or two. They have that technology.
Another trick I've been thinking about would be a spacer between the bottom strut bolts and the rest of the suspension. It could space the strut inboard and upward at the same time. Coilovers can also be made to mount on top of the strut towers. Strut towers can also be welded so that they are taller. That moves the strut upward so that the skinny part of the strut is next to the sidewall of the tire. Moving them inboard too much would prolly screw up the steering, I think. |
