What Size Spacer Should I Buy?

I want a little poke in the rear but I don't know if I should go with a 15mm or 20mm spacer. I have 17" Style 5's and I plan on running 205/40/17 size tires on the back. I plan on lowering my car soon as well.

i don't think you need spacers, you already way out, you might rub if lowered.

I've seen a few cars run 17x8 et0 in the rear, it's very very aggressive, probably on the lines of what you're looking for. With your 17inch style 5s that would equate to a 20mm spacer, I have our ECS Spacers with extended wheel bolt avaible HERE.

Now since everyone has a different preference I'd suggest getting the tires mounted and the wheels on the car and take a look at how aggressive you'd like to go from there.

Spacers should be last. Get tires on there, Suspension dialed in, do all your fender mods and then measure.

I'll wait till I get my tires on after I finish refinishing my Style 5's. Also I want then to poke a little because my fronts poke without any spacers. So I run an even more stretched tire?

I don't know if this helps, but I have 225/45 tires on same spec wheels...

This is w/o spacer at all:


This is with a 12.5mm spacer:


BUT! I'm on stock suspension and it rubs on really big bumps, or if someone else is in the car. I'm taking my spacers off, they don't rub at all without the spacers.

Once you get the tires and make the necessary mods, use this tool to help you decide what size spacer you need:

You should buy a tape measure mm spacers.

Tampa02e46 - from your photos it looks like you could roll the fenders and no longer rub on bump, have you figured out exactly where you are rubbing?

Yes, i think you are correct but I don't have access to a fender roller and actually just sold my 12.5mm spacers w/ext lugs for $75 to a forum user...

I'm going to let these tires eat up before my mess with my suspension/offset again. I only have 225 in the rear on 8" wheels and I want something wider, so when I do that, I'll decide on spacers again.

OP, sorry man I forgot to take a pic like you wanted with the spacers on , but I took a shot with NO spacer, remember these wheels have the same offset as yours. What size tire are you going to run?

I plan on using 205/40 all the way around. I also plan on rolling my rear fenders so I dot think I will have rubbing issues with a 12.5 or 15mm spacer.

If you go 205/40, I'd go with a 15mm for sure if you want poke.
