I am looking for aftermarket rims but its hard finding decent ones with 5x115 bolt pattern and I have read some forums and guys saying they have used 5x114.3. I'm a little skeptical about using this bolt pattern but I'm sure it will work just don't know how well? I have a gp gt with 17" rims and would like to go up to 18s would 18x8 work for front and rear cus I also know the gxps have different size front and rear rims being 18x8 and 18x7?
