I need to buy some spacers. I believe I can fit 5mm,10mm,15mm or 20mm spacers. I also need to increase the bolt length.

Is there any less of a downside to a 5mm versus a 20mm spacer on the bearing?

Do 5mm spacers come with longer bolts? If not what are my options?

Do I need anything else? New lug nuts or wheel locks?

Thanks.

 

You should be able to get away with a 5mm without extended studs. General rule of thumb is you should be able to get about 7 full turns of the lugnut.

 

Well, I test fit the wheels today and I do not believe that I could get 7 turns.

 

15mm in the front with bring the tire flush with the fender. Will the tire hit my fender?

I am about to order some spacers, but I am just looking for some agreement. I have measured my coupe's stock 18x8 +30 offset oem sport wheels. It looks like they can fit 15mm in the front and 20mm in the rear; as shown in this thread: https://g35driver.com/forums/brakes-suspension/121020-pics-my-car-lowered-z-springs-kics-spacers-x-drilled-rotors-death-56k.html.

The wheels I am putting on are 18x8 with a +35 offset. Can I use a 15mm(f) and 20mm(r) spacer setup on these as well and not have problems?

Thanks.

 

If you're going with a +5mm larger offset than stock (which will sink the wheel further into the fender) then you should increase your spacer sizes that are well-known to work on stock wheels (15mm front, 20mm rear) by 5mm to compensate.

You should get 20/25 or 25/30. There are several people around here who run 20/25 spacers on stock wheels and have no rubbing issues. If you want to play it safe, go with 20/25.

 

Thanks, for the reply. I figured that I should make them 20/25. I just don’t want to run into problems.
