Wheel gurus
I had a set of BBS RGRs for my Z32 and sold it to local buddy so I can but the BBS LMs. Everything worked out perfect on my end. My buddy wound up getting married and having a kid so he never used the wheels. He asked if I wanted to buy the RGRs back. The are 18x 9.5 all around. Offsets are +38 and +30. Both vehicles have the same lug patterns. Will these fit the RX7? I don't want them to poke out since I don't like the rocket bunny kits or the stance look. I'd plan on putting 265/35/18 tires on them.
if this doesn't work out I plan on getting the BBS wheels off a EVO X MR

My rear offset is +30 and to me it is out a tiny bit too much. This is 18x9.5 and 275/35. The fronts are 18x8.5 +35 with 235/40. I think the fronts are perfect.

Hopefully someone will chime in. I think you need a 50 offset for the front @ 9.5 wide.

+35 at least with a roll will work. 30 is pushing it.
17 or 18x10 with a +45 is about perfect IMO. I run 17x 10 +48 with a 255/40 tire. Everything fits fine under my stock fenders and I don't rub at all.
I'm sure plenty of people here will tell us that you can run those wheels and be stoked and they're right. They WILL fit, but you're gonna need a roll and some camber to do so without rubbing, and that camber eats tires.

Not claiming to be a guru, but I just studied up on this recently...
Download the wheel and tire sizing spreadsheet for FD that testrun is using.
265 35 18 is considered by many to be too tall for the front. People will tell you to keep the front tire height below 25" and for good reason.
I run 255 35 18 up front with +43 offset and had fender lip rubbing until adding -1.5 deg camber and new strut mounts. You will likely have some rubbing with a taller/wider tire + lower offset.
You can run 9.5's on a lower offset than 50, but you'll need to run a narrower tire. Offset drives tire width. 255's up front will be your best bet for unrolled fenders, but like I said I had minor rubbing with 255's on +43.

18x9.5 +30 will fit in back with a 255/35-18 tire, but you will have to run on the higher end of stock range of negative camber (like -1.3 to -1.5 deg) to make sure it doesn't rub the fender lip on full compression. Or roll the fender lip under.
18x9.5+38 will fit up front with 255/35-18 tire, but you will have to run negative camber in excess of stock range of alignment settings (like -1.5 to -2.5 deg). Or roll the fender lip under; which in the front is a good precaution if there is any chance of tire touching on compression and turning as it will wrinkle the fender if tire hits unrolled fender.

While I'm not into the biggest tires, I run 18 X 9.5's +42 with 255 X 35 all round and it works very well and looks pretty good, imho.
