Honestly with 25mm in the rear on 255 wide Dunlops or RS3s, I've have no issues with running 2 degrees of rear camber. No rubbing on the street and no rubbing on the track.

Bumper inner lip is "trimmed", fender is rolled (not flared), and bumper tab is relocated 3" back.

 

^^ Also depends what your ride height is and where you are using your car(street or Autox/track).

But from personal experience and getting more and more into tracking I'm would stay more on the safe side.

I'm straying away from looks and being more performance oriented now than I was a year ago (when I had that setup w/ the spacers).

 

the outside edge of the tire stays in the same relative position based on offset, not wheel width.

 

It's based on wheel width and offset. I.E. 17x8 +45 and 17x9+45 don't stay in the same position relative to the fender. 8 inch sits 4 inch -45mm in and 9 inch is 4.5 inch -45mm in, 1/2 inch (12.7 mm) more outward (closer to the outer edge of the fender) than an 8 inch wheel.

 

Since i already have 15mm adapters front and rear, do you think i can only add an extra 5mm or 3mm spacer without any issues. Im on koni/eibach lower perch only in rear and i roll 215/45/17 245/40/17. If possible, witout rolling or cutting anything. Should i ll be fine by just getting more camber?

 

just to add some additional info, i managed to fit 20mm F 25mm R on ap2v2's with no issues. i have pss9's lowered all the way with rolled fenders and tab relocation. i think i couldve gone 25mm all around and not have any problems. i am very pleased with the results since the wheels all sit much more flush with the fenders.

 

pix?

 

there needs to be a wheel bearing replacement thread after seeing all of this lol

 

 

Hah, same goes to cars with lower offset wheels... Wheel bearings are a wear item and go out quicker if you have more aggressive offset wheels and/or stock wheels with spacers.

Thanks for your input.
