View Full Version : Are you running 9.5 rims on front?

Can 9.5 x 19 rims be run on the front? If so, what tire size works, and is a coilover required to get the required backspacing?

I'm looking at 19 x 9.5 with 45 offset, may be able to get 35 offset as well. Willing to wait until coilovers installed if necessary to fit, and willing to run spacers if necessary.

Thanks

Not me, but here are the exact setup you are looking at, 19 x 9.5 w/ 45 offset. He installed a 5mm spacer to clear suspension.

So running a +45 offset with a +5mm spacer... is like having a +40mm offset with no spacer...

How would a +40mm offset work with 9.5s on all four corners?

I think you would definitely rub in the rear, especially if lowered. I rubbed with 9.5" 45 offset with lowered Pedders springs until I rolled my fenders.

That's what I have currently. Don't have them on the car yet because they'll be my summer setup.

The 40 is a little low for the rear, but should be OK with a stock suspension. +40 on a 9.5" rim up front is perfect, you can run a 275 wide tire on the front no issues even lowered.

My girl can only take 9.5" in the rear, don't fit up front...BAM!

Sounds like I have a plan. Thanks.

I think [+40mm] would definitely rub in the rear, especially if lowered.
So without running spacers up front, there really isn't any way to run the same offset 9.5 on all four corners on a lower than stock car. Good to know.

We are in the same boat then. I'm interested in running 9.5 in front as well with a 275 if possible. I won't have coilovers though so I don't know if I can pull it off. I need to figure something out to clear H&R springs and still be able to rotate all four tires...

Try contacting "Realsquash" on this board. Think he is running a 19 x 9.5" setup with +40mm on all four corners on his Pedderized car.

Where are you getting all of your good ideas from?

Seriously, how am I going to be able to keep-up with you on the Auto-X if I don't have wider tires than you? :huh:

Yeah, realsquash (Andy) had a 9.5" wide rim on front on stock suspension, no issues with a 275mm wide tire. Lowered, he has no issues with NO OTHER modifications to the front.

Only issue will be the rears. I plan on getting two of the wheels milled down a little to increase the offset. if I can go 5mm to 8mm down on the "rears" I'll be all set.

Can you run 40mm offset all around? Yes, but you will need to uber trim your rear fenders. I run 45's all around, no spacer in the rear but 5mm up front. It's the best way to run the same wheel front and rear. I ran that setup with 100% stock suspension and now with the car lowered quite a bit and 275/30-19's currently. It was fine with the 275/35-19's as well...

I want to get 305's to fit up front this winter if I can get the damn thing out of the snow.

What is your opinion of running a 5mm spacer up front on track days? I'm a little hesitant to do it (just one more thing to break), but have no real data to base that on.

That would be awesome!

That's a lot of front tire!

So should 18x8.5 +38 front and 18x9.5 +38 rear work on stock springs?

Need more offset on the rear. Fronts should be ok.

That's how Andy ran on the track (with spacer I believe). I'll let him confirm. Check out the thread on the other board, he's got pics there. Maybe he'll post them up here.

I ran all the track days (6 or 7 of them) with 5mm aluminum 6061 spacers. I don't think I trust the cast ones that you can buy for $10 at the autoparts stores though. I wouldn't go over 5mm thick on the stock length studs, either.

Very good to know! Sounds like they can stand-up to the task.

Yeah, I'd only go with something machined and would probably get longer studs just to be safe.

I machined my own for the front but I bought a couple from a guy on eBay - http://cgi.ebay.com/ebaymotors/5mm-HUB-CENTRIC-WHEEL-SPACERS-BMW-5x120-CB-72-6-_W0QQcmdZViewItemQQhashZitem35a98d74c4QQitemZ23047 7886660QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccesso ries. I've been running his on the rear with the 305 DR's since I didn't have time to make my own. The only difference is that the one I made fits snug over the hub, but his doesn't. The stud holes are tight enough though, it's not a problem if you ask me.. He might make a custom set, too. Good guy to deal with.

Andy, please tell us your whole setup as far as rim size & offsets along with tire sizes, that you were able to run with stock spring height. Thanks a ton!

I ran the exact same wheels, tires, and spacers both with 100% stock suspension: 19x9.5 ET45 with 275/35-19 Continental DW tires. I used a 5mm spacer on the fronts, none in the rear.
Then I installed the Track 2 Xa and lowered it. I don't remember my ride heights but it's pretty low. I didn't change anything with the wheels/tires, it all worked fine. -1.4* camber up front as well, which takes up some of the gap between the Xa body and the tire up front.
Then I swapped the tires on the same rims to Yokohama Advan AD08's, slightly smaller diameter at 275/30-19. Again no changes to wheel and spacer combos.
Then I decided I wanted to go fast at the drag strip so I bought some Z06 replica wheels, 18x10.5 ET58 and running a 3mm spacer, and 305 MT DRs. You won't need the spacer if you have stock brakes but the spokes barely clear the Brembos.
