Rim/Rubber sizing
Sorry Randy, but getting close to selecting wheels, question;
I looked at wheels from a '05 Carrera 5 spkoke 18" x 8 et57 and x10 et58, however rubber is a concern. Fronts are 235/40 and rears are 265/40 , is this a desirable size, would they be too tall? I believe most here are using 225/40 and 265/35.
Are these a direct bolt on, would I need to remove spacers on rear, is stud length(too long with stock nuts) an issue ?
I know I have asked of many for help , but want to make the correct choice.
Thanks

Rears are bit too high IMHO. 265/35-18 would be as good as it can get.
Code:

How about 285/30/18's, they are 24.8" tall and will fit on a 10" wide wheel with no problems. (It's what I run!)
The 265/40/18's are fine to run and will cause no real problem, just a slight speedometer deviation. They are what Stan runs on the Canary and they look fantastic, fit perfect and work like they were made for the car. Yes, you will have to remove the rear spacers though...

After removing spacers, what about wheel stud length? Do I need to replace with shorter length?
Also, will the differnce in wheel diameter front to back be of concern?
