I have some Rohana Rc10's, they are 19×8.5. What size spacers would I need for the wheels to fit flush with the fenders? Thanks for the help. (Car is stock)

 

Depends on what the offset is now.
What's the offset and I'll tell ya....

 

The offset is 35..

 

15mm spacers will be fine. 20mm to be a bit more aggressive. You'll also want to list suspension mods and alignment spec to narrow it down more.

 

Sorry to hijack here but I have also been debating on what size spacers to get if you could help.
Wheel specs are 19x9.5 +35(originally +35 but I have 5mm spacers in the pictures so +30)
Only have z1 camber arms and coilovers for suspension mods.

 

What's wrong with the look you have now?

 

Wanted it to sit more flush. I only have the 5mm now for the caliper clearance purposes.

 

I guess our definitions of "flush" differ.

 

Remember, in the rear, you'll probably want to dremel some of the plastic liner and trim that rear bumper bracket if you plan on getting more flush.
