Low Offset 9.5" Front Fitment?

[3002 tii]

Anyone running 9.5 et22 in the front (with 265 rubber)? If so, mind sharing suspension/alignment specs and what else was needed to get it to fit?

I have enough issues dealing with 18x9.5 +20 on 245/40-18 RS4, the tires rub on the fender, bumper, and inner fender liner, mind you i am hoping to bring that back to +22 with my helpers removed, but I always have a fear of rubbing on my KWs on the inside
Front Camber: -2.8

Thanks very helpful... assuming no change in camber, how many mm clearance do you think would alleviate the rubbing? Do you think raising the height would help?

Hard to tell, but the rubbing wasn't even on the fender, its on the front (and partially the back) part of the fender liner, I had cut about a 1 1/2" slit in the fender liner (between the access door to the headlight to the edge of the bumper pretty much, and I still rub on occassion at the track with the suspension loaded. From rub marks on the fender liner I am convinced I need to cut another 1/2-1" off the fender liner for it to fully clear.

Raising it did help in terms of rubbing on the fenders, previously I was for sure rubbing on metal, and first time I went out to track with this setup before I had my height adjusted, I was rubbing fender, fender liner, and even dislodged the front bumper every time I come off the track.

basically what I learned is, more camber will help as long as you aren't touching the spring perches or the spring on the inside, so will height, but ultimately if you are lapping it, you will likely rub on the liner like I have.

Yea I know exactly the area you’re referring to. I had that same issue on my previous 3.0si when I ran a taller diameter tire (i.e. it was not a width issue). I wonder if 265/35 won’t be as bad since it’s a little shorter than a 245/40.

I don't think it matters. Even my sunken skinny stock 225/45-R18 tire (similar sidewall height as your 245/40R18) on stock wheel - ET42 have a slight rub in that area on compression!

I ran 9.5" et35 + 12mm spacer = et23 effective for a week or so with both 255 PS4S and 265 Trofeos, 3.2 degrees camber, 9 degrees / max caster. This setup rubbed fender liner at full lock + scrub radius increase didn't feel great and I went back to the 5mm spacer I usually use.

I am guessing at 23 and camber you manage to clear the fenders.
What suspension setup you on and how low are you. Where are you rubbing on the fender liner. I am suprised you didn't rub on the inside at +30, I rub my coilover at +25 and im only on 245 tires.

I'm running 9.5 et 26 with 265's ....define fit. I've been running that size for over a 100k and am now back to maxed camber on stock suspension, fits with a bit of poke but no issues with anything but the front fender liner at the front edge of the wheel well. But that was done in years ago running slicks on the track so hard to say for sure if it would completely clear.

MCS 2-ways with 60mm 6" springs and very short Hyperco helper springs now, maybe .5-1" lower than stock (around 5.5-6" measured at front and rear jacking points) - wheel clears the strut by 5+ mm when I use 5mm spacers behind 9.5" et35, 265 Trofeos clear this setup too even with their fat sidewalls. Tbh I don't know how a perfectly stock, intact fender liner would clear this setup, mine has seen lots of rub over the years near bumper's upper mount point but almost no wear elsewhere closer to center of the car or behind the front axle line.

I see my issue at least, KW uses 70mm springs, I already lost more than 5mm than you

Guess I just cut a bit more fender liner or raise the car a bit

i'm a bit late to this party, but AriuSen here on zpost had square 10et25 and 265/35r18 for track. reverse engineering to a 9.5et22 shouldn't be too hard from that. Apex has some of his stuff listed through their gallery pages from before he sold the car. i am unsure of who owns it now.
