Hey guys I been searching without any luck...So I pulled out the card and screaming for help.....As I am NOT confident enough to order the wheels off my own measurements

I need measurements for a custom one off set of drag competition wheels for my second Drag only EVO 9 MR / SHEP 5 speed swap .....

unfortunately I don't know what I am measuring for....

I am getting (4) 17" X 9.5" Custom billet drag only wheels and they only take measurements in inches except for the offset


The company is an all american company and is not familiar with my car....They said they need to know the following:

correct backspace: which is I believe, from the rotor face side to inside edge of the wheel

stock brembo brake clearance is also needed to be accounted for so I need to know that info also....

and an offset where the wheel is perfectly within in my fenders.....I am excited as these are my last parts that I need to order to complete my 800hp drag beast.....

I've spent the last 4 years of my expendable savings on this car, not to mention my money pit daily driver, so I need this to go right.....


Thanks for your help guys, I really appreciate this....
