Hello All,
I am deciding on the wheels for my car and now have a number of choices. There have been other threads inquiring about the wheels to run and I now have my view on the limits. By limit I refer to the rim alignment with the edge of the wheel arches with the suspension loaded.
For the front, I have found the limit to be 8" wide with an offset of positive 20. The ET20 clears the leg of the strut by about 5mm.
For the rear, I believe it is possible to run 10" wide with and ET10. I state this because I have put a 9" RC91 on the rear and there is still close to an inch space. By decreasing the offset to 10 to bring the wheel out further and increasing the width by an inch, I think the face would be near in line with the edge.
While I have an RC91 barrel, I have RC90 faces to decrease the offset marginally. I attach a photo of the result at the rear. Tomorrow I will install the front and take a picture of that too.
I recognize that running excessively wide tires at the rear would change the balance of the car and likely substantially increase understeer. Secondly, it is also clear that the double inner fender metal would limit the amount of rolling the lip to allow a wheel to be run so far out, but I believe with a narrower tire it should be possible. Looking at Christian Heine's E9 on it appears possible to successfully run a more aggressive stance.
