From what I can find online for BBS LM Reps is.
F:19x8.5 (+35)
R: 19:9.5 (+38)


And I don't know how to determine the least amount of camber I can run without them hitting the fender. The alignment shop said it was still rubbing on something so they maxed out the possible camber with the bolts installed. To me it looks pretty close to the fender but it's hard to tell exactly, any suggestions?


They are defiantly rubbing on the fender liner and bumper tabs though (shaving back the tabs tonight) but will probably just let them rub the fender liner the odd time, I don't feel it's necessary to trim it back as it won't hurt the tires if they rub.

Those offsets seem to be more conservative than what your pics show, and you list a 8.5/9.5 above but on the first page you list 9.5/10.5 inch setup. The fender liner will just buff & shine your sidewall until it wears enough not to be an issue, that tab is probably the culprit. When you remove the wheel you should be able to see exactly where it's making contact.

I shaved my bracket using a dremel cutoff wheel and I only have 9.5" wheels and 265 series tires. I am using spacers and visually, it appears you have substantially more poke, like 20mm worth of poke, maybe more. What's your wheel offset? It honestly looks like it's poking way too far out to make it work. Negative 3 camber is just stupid on the street if you value your tires wearing properly and lasting for more than a few months.

yeahmy bad they are the 9.5 rears. I had the rims off last week and could not findthe offset inside the rim. The numbers I saw were as follows:
Gk069
12+++++
11+++++
3342R
9.5JX19H2
ET:20
PCD:114
CB:73

Theyare BBS LM Replicas if anybody can find the offsets (9.5 rear)

I'venever ran camber on a vehicle before and didn't want to run -3 but Igot the tires so had to get them to fit. I live 5 minutes from work so I thinkthey will last more than a few months and it's only a summer car.

Checkout how they fit after the camber, I could possibly get away with -2.5 or -2but I don't know how to determine it for sure and can't afford getting a $100alignment to go down to 2 to find out it doesn't fit and have to get another togo back to 3. Any suggestions?

9.5" is more within the realm of possibility but that's a big offset number. I run an effective offset of 35mm on mine and it's flush, necessitating trimming of the bumper bracket. I run about -1.7 degrees of camber but I want to bring that back in a bit to -1.5 in the rear for better straight line traction.

You're going to have significant tire wear with those settings, especially if you do a lot of highway driving.

What size tire are your rocking? So do you think I can get away with less negative camber without rubbing on my fenders/ what is the best way to determine the least amount of camber possible without rubbing?

Your offset is +20, running 275s should tuck ok without that much camber. There's a coupel coupes running 10.5 +25 on 275s and they clear ok without that much camber, so on paper you should have 8mm more (13mm more room for the narrower wheel but 5mm less room for offset) for a net 8mm more clearance at the fender~Here's one example~But OF COURSE, it's a photophucket pic, and they'll all been lost!

If you don't mind running a little stretch 265 should fit pretty well. I'm running 265 on 10.5 with an offset of +10 with 2 degrees camber and it fits perfectly. I'm also dropped around 2.5 inches all the way around.

If you're running 265s on a 10.5 +10 that's 23mm further out than the OP, plenty of room for 275s then

Yeah that sucks the pictures are gone, I may send Simpson a message and see if he can repost or send me them. But there is no way these rims/tires are fitting without "non-factory" camber. I can't believe that simpson is running 20's with 10.5 and clearing, I would love to see those pics ahaha.


SO how would you recommend I proceed?
I have been lining my wheel well with painters tape so I can see where the tires are making contact, currently no contact with the actual fender, I seem to be clearing one sides fender tab but still slightly rubbing on the other (I will shave back another mm or 2, but I am getting close to the bolt) and I am making obvious contact with the fender liner which I am okay with.


My thoughts would be to mark where I have it aligned now, scale back the camber to roughly -2 or -2.5 (doing this at home so it wont be perfect), then by evaluating the painters tape determine when/if I make contact with the fender and adjust camber until I am clearing??? Finished up by an alignment at the shop for the third time aha.

That bumper tab often needs to be nearly 100% removed, probably the case w/ yours too

I have a 09 g37s coupe on 245/40 front and 275/35 rear, 19x8.5 +15 offset all around on BC Racing Coilovers. I raised the rear all the way to maximum height, but still rubs on pot holes. Im not sure if its the 275 tire, the +15 offset. I was recommended trimming my inner fender linings, smaller tire, and even camber kit to get negative camber. Im not sure what my best option is. I want to lower my car even more down the line after the rear rub is fixed, cause riding at maximum height kinda sucks.

saywat?

if ur just rubbing the liner just trim the liner. or are u rubbing the bumper tab? im assuming liner based on ur wheel width its quite narrow even with that offset
