Hi guys, I got 9.5" width wheels at the back for my S15, in order to pass the engineering certificate, I need to strengten the whole back end of my car with car that has standard 7.5" instead of 6.5" (on the S15) so my option is the GTR end, diff, bearing etc whatever controls the end of the rear wheels, now my question is where can I source one out? and who should I talk to get the work done?
Please don't tell me to swap the wheels to 8.5", coz I already bought the wheels and took me 1.5 months to get them
Thanks for the help in advance
