If ordering custom, you need to inform or clarify with the store what specs they are ordering....Heres what I intend to get..
Front 20x9J with ET 25~30 wheels with 245/35/20 tires with PCD of 112 x 5 with center bore of 66.6mm
Rear 20x10.5J (I may go for 10J) with ET 35~40 wheels with 285/30/20 tires with PCD of 112 x 5 with center bore of 66.6mm
Pics from Kelvin's car...not sure his dimensions but his offset is printed on his wheel. Power right? His front ET is 27 and rear is 34. Guess you are not lowering so no need to worry about rubbing, if you lowering, best to use a little more positive offset.
