You should be fine with that. You could even do 9's all around at that offset if you want. The fronts can actually swallow a good amount of wheel. I know this because my front 8.5 offset is in the 20's.

For the rear if you are going to do a 8.5 et 35 maybe throw a spacer in there to balance it out. You can easily put a 12mm spacer in the rear with a touch of camber. Again I know this because of my current setup.

Before you ask I know the offsets on my setup but I can't post them yet do to a sponsorship agreement. They have to post first.

Good luck. Might I suggest some volks. A square TE37 setup would be !



Hi dude, I need ur comment for Rays G25 wheel in 19" :-

Tyre shop said that I can install front 19" with ET35 running 225 x 19" 40 or 235 x 19" x 35

and rear 19" ET35 running 255 x 19" 35 or 265 x 19" x 30.

So, F & R would be in ET35 ( http://www.rayswheels.co.jp/2009/pro...-19&for=import ), so in this ET35 what will happen on the wheel? Very close to the fender but won't hit it even car has been lowered by replacing of coilover? Or, the rear will goes far from fender which has made the front wheel look wider than rear?

Thanks.

What is the width of the rim? The tire's section width will change based on the width of the rim you mount it to, and that'll determine whether it rubs or not.

FYI, the stock setup for 19" staggered is 19x8" ET36 225/40/R19 front / 19x8.5" ET47 255/35/R19 rear

This obviously doesn't rub

okay got mine mounted up this weekend and it didnt go as smoothly as planned only because I had some clearance issues with the MPerformance brakes in the front.

Here is my setup, Keep in mind these are my track wheels hence the aggresive tire size and offset
18" x 8.5 ET37
255/40 Yoko Neova ADO8

Rear fitment is perfect
Fronts were hitting the caliper so I used a 10mm spacer to clear

The 255/40's are a little beyoned squared on the 8.5 so the front is poking outside the fender by a good 1/2". Gonna try and get it on the alignement rack today to see how much negative camber we can dial in (not expecting much). The front fenders can be rolled so I may try that later on.

Despite the less than ideal front fitment, on the street they only rub when encountering the dreaded high-speed dip. So being track wheels I'm concerned with high speed cornering and sweepers

Hopefully there will be some camber plates coming to market in the near future, but worse comes to worse I trade out the 255/40 for 245/40 in the front and call it almost square

i'll snap some pics next chance i get

-Scott

If you didn't have the caliper clearance problem, would the extra 10mm be enough to tuck the wheel into the fender without any extra negative camber, or is the 255's section width on 8.5's just too much for the wheel well?

How much extra clearance between the tire and suspension do you have now? Would it be rubbing there as well without the spacer?

based on how much they poke with the spacer I'm inclined to say it would still poke a bit even without the spacer

Didnt look at the tire/strut clearance without the spacer but its close with the spacer so it may contact without the spacer. I'll be taking the wheels off later this week so i'll explore the strut/tire clearance

Hmm.. I guess maybe I'll just stick with 8" rims all around and push the tire size up to 245/40 on all 4 corners - section width of 245 on 8's should only push the clearances out ~6.5mm on each side - I can't even hold my fingers that far apart steadily that's got to fit

BTW scott - love love love those Modulare B18's in your signature - color me jealous

Thanks!

Got the car back on the lift and checked the tire/strut clearance without the spacers and you have about 1/4"

I'm gonna try a 5mm spacer next to see if that will give me enough brake clearance, then I'm gonna get it on the alignment rack to see how much negative camber can squeezed out without modification (not expecting much)

I've got the stock 18" sport square rims (style 397 8" front and back) - maybe I'll just try shoeing them with 245/40 non-run-flat rubber and see how that goes

Might buy you some rim protection from scuffing as well
I went with 235/45/18 on the front, stock 255/40/18 on the rear.
Works great.
Could have done 235/40, which would have been .3" less diameter over stock.
235/45 is .3" larger than stock.
Not much difference either way. I figured the slightly taller sidewall would be beneficial if I hit a pothole.
Since I'm going with AS tires I decided not to any wider on the front.
245/40 all around sounds like a good option too, especially for people not driving in all season areas.

I like the steering feel with these Conti DWS tires. Seems to be a touch more "road feel". Also, I upped the psi front and rear by 6psi as the DWS have a bit less initial steering. With the upped psi it feels about the same as the OEM S001's at stock pressure. Ride quality is excellent and bump absorbtion is a good bit better than the RFT's.
I had these on my 135i with the higher pressures too. I'm loving these tires and the extra width on the front feels very good.
Plus these tires remove over 20lbs of unsprung weight compared to the RFT's.

TireRack has been using 245/40/18 on the F30 328i's they use for tire testing, using the 8" wheels all around.

Looking for a square setup for the track as well. Some apex wheels. But they havent fit/built any for the new f30 series so gonna have to calculate myself.

They have some 18x8.5 et35/45. Im guessing i can do 35 up front 45 out back with the same tire size. Rotating can be done at a tire shop i suppose since they will only be for the track.

These will be fitting with some coilovers.

Need a better track setup ASAP!

Do you think with the 328i stock baseline brakes the 255 would fit?

Im ok with a little early braking just want the tires to help me steeeer.

Hmm - if you're going with the same size wheels in the front and back, I might put 10mm spacers on the wheels with et45 (to make them et35)

Reason I say that is the stock square setup (8.0" et34) is the same offset front and back. If you ran the 45's out back with the 35's in the front, the front's would stick out and the rear's would be sucked in by comparison

8.5" et35 should be close enough to stock to fit. It would stick out a little but is negligible. With 245/255 im hoping it would fit. Scottbmw can you chime in and let us know whether or not the bbk was the reason they did not fit? If you had smaller brakes would you have had no fitment issues with 18x8.5et 37 with 255.40 all the way around?? Please let me know thanks. Your pm box was full the other night.

alright, 5mm spacers didn't cut it and there is no additional negative camber adjustment available with the factory settings. So at this time I'm left with either modifying the front fenders or going down to a 245/40.

I've decided to go with the later since I'm concerned that without additional negative camber up front the 255's may not provide any additional improvement on the track (information provided by some others more learned on the subject of track suspension setup).

The O.E. brake shouldnt have any clearance issues and I don't see running a ET35 8.5" with 255/40 being a problem (cosmeticaly it may look bulky and akward) I'm running a ET37 8.5 with a 10mm spacer to clear my Brembo's so this is essentially a ET27 8.5

here is a picture of my set-up for reference

bit the bullet and went down to the 245/40 for the front...fitment is much better with no indication of any clearance issues. Here is a pic for reference

again this is a 18x8.5 ET27 with a yokohama neova ADO8 245/40

Thanks Scott for guinea-pigging this for us - I'm sure I speak for everyone, this is so much help

But dude, run a rag or something over those rims before you take pictures

if you look at the rear in my picture you'll notice its just slightly tucked and thats running 18x8.5 et37 with a 255/40 ...keep in mind the yoko neova ADO8 have a pretty squared beefy sidewall

I'm planning to get 19x8.5 et35 all around with 245/35/19 & 255/35/19. Should work nicely without rubbing or hitting the struct, right?
