Need help with 19" BBS LM/LM-R sizing

Well I have reached a crossroads on whether I am going to keep the 1M or trade it in for something else (GTR or R8). I am leaning towards keeping the 1M and have decided if I do I am going to be getting new wheels and tires for a more unique look.

At the front of my list is 19" BBS LM or LM-R in DBK finish. Second choice would be HRE P44SC or P43SC. My question is how aggressive of an offset can I run without rubbing or very slight rubbing? I am currently running KWV3 coils, stock wheels, and 10mm spacers all around. I do get some rubbing on the front when the wheels are turning (I think some people have reported this issue with stock suspension and wheels).

I am thinking the following:
LM-R: 19x8.5 ET 22 front, 19x10 ET 20 rear
LM: 19x8.5 ET 17 front, 19x10 ET 25 rear

Any help would be appreciated. Thanks.

Some things we need to know are are you looking to maintain stock alignment specs or willing to run more camber to fit? How aggressively are you lowered? What tire sizes will you be running?

Based on the rim specs you posted, you'll be able to get away with a front spacer of at least 10mm with a stock sized tire. It will rub on the front of the liner when turned near full lock but that even happens on the stock wheel setup. If possible, rebarrel or get a wider rim, something like 9.5" or more.

For the rears, you could run at least a 5mm spacer, when combined with a 275/30 tire. I'd suggest just going with a wider rim or rebarreling the rims to get them wider; you could probably go up to an 11" rim

FWIW I'm running wheels that are 19x8.5 +30 w/18mm spacer up front on 245/35 hankooks, and 19x10.5 +25 rears on 285/30 hankooks. No rub in the rear, slight rub in the front near full lock.

Use this calculator to figure out where the new rim will sit in comparison to stock :
