PS + wider wheels = fender rub
After installing PS the tires hit the fender when loading the suspension after a high speed bump.
I am going to have the fenders rolled but I really want to stiffen up the rear suspension specifically. Looking for suggestions (I'm thinking): - Rear sub-frame bushings |

Can we get specs on your wheels and tires?
Also bushings will only control yaw in the rear suspension, they wont do anything for fender rub. |

No those are your rear tires.
What are your wheel specs? Width and offset? |

You really shouldnt be having trouble with that. That makes you at an 8.5 et 42. with a tire that has a pretty rounded shoulder.
You sure that your alignment is in spec? |

You would need something to make the car less bouncy which would be coilovers but that wouldn't work for you since you bought the PE suspension.
After I put on my KW V2's it got it of about 95% of the bounce the car came with. |

255 at 42 offset sounds like a recipe for rubbing to me. Dang close anyways.
So - you added a 10mm spacer and moved the wheel / tire towards the fender. And now the tire rubs the fender. Is it just me or doesn't it seem obvious to remove the spacer? I don't know the stock wheel data but if that puts you at a 52 offset you shouldn't have any problems whatsoever w/ a 255mm tire. |

It was supposedly aligned when I had the PS installed. I guess I will take it back for another look.

How about getting some neg camber on your PE suspension? That should help a bit.. Have your alignment guy dial in some neg camber and drive it around and see how it feels.

Also you can really aggresively roll the rears. I honestly see no reason why youre rubbing back there.
But if you have big problems with it why not get a set of Koni Yellows for the PE springs? |

Sounds like killing a fly with a shotgun. My rear wheels are 17x8.5 et 44, and I had a slight roll done in the rear. I experienced some rubbing with 255/40 Hankook tires. So depending on the tire that you have, sounds like probably you would rub. No need to go back to the shop and check the alignment.
You could max out camber. You could roll you fenders. Don't think subframe bushings are going to do anything with your issue. Don't think you would want to make just the rear stiffer, unless you are talking about some of the squirm and wiggle in the rear. Then I take back my last statement, get the rear subframe bushings, but that still won't help your rubbing issue. It all just seems like overkill. The answer is simple: take out the spacers! If you really like the look of the wheels being pushed further towards the fender, then just get smaller spacers. Assuming you changed your suspension and put 255/35 tires in the rear with performance in mind, maximizing camber just for the sake of fitting wheels will not help performance. Getting a proper alignment would be a great addition however, which you received with your suspension, so no need to change it. My .02 Tim

You said you were on stock wheels with a 10mm spacer, so your wheels are no wider. If you're considering buying wider wheels and want to know if it rubs then you need to give the specs of the wheels. Wider wheels are not necessarily the same as the set-up you have. It will depend on the width AND offset of the new wheels.

Technically you are correct. However, the amount of space taken up by the wheel + spacer is equivalent to a wider wheel.
I measured it and compared to a wider wheel and it is the same. Net, net is how far out the edge of the wheel/tire is in relation to the fender. |

I recommend M3 rear subframe bushings with the PS suspension anyway. I doubt that will help the rubbing, but whatever - you already said you're getting the fenders rolled. I would get rid of the spacers, but I guess you want that flush look.

compared to which wider wheel? whether you're comparing against a et45 versus et62 makes ALL the difference. also, please don;t adjust camber to fix rubbing. that's just bass ackwards. remove the spacers, try smaller spacers, or get wider wheels with higher offsets

take off 10mm spacers, replace with 5mm spacers

E34m5, the amount of space taken up by the stock wheel + spacer is NOT the same as a wider wheel because a wider wheel would use a completely different offset. APEX 8 wheels are an inch bigger than your stock wheel and can fit a 275 wheel but fit without rubbing because the offset moves the wheel towards the inside.
