I'm dropped on Tanabe NF210 springs, with 20x8.5 +35 and 20x10 +35 with 245/35/20 and 275/30/20 tires...i know my offsets are high but i like the wheels and I have ichiba 20mm spacers that need to be installed...which would make it a +15 all around, just wondering if i'll rub or do i need a fender roll?

 

Measure the distance between the tires and fender.
How far do you want to move the wheels? 10mm? 20mm? 30mm? There you go.

 

David, I find it surreal when you post with serious answers.

 

measure the distance as david says. If its more than 20mm you wont need to roll your fenders if its less then you wont simple enough.
