BBS RS 001's are a 4 x 100 wheel and are 15" diameter. these are wheels for 2002 or e21 / e30. they have 30 bolts. the 005 / 006 have 34 bolts. now it it possible to fill the holes and drill new holes .. this is done all the time by Ehrlich to create wheels for e30's / e21 + 2002.

@rsporsche ,

Posts are split. Please bear with me while I update the attachments. When you clone posts, it doesn't clone the attachments. Rather, it shares the same attachment. I'll need to re-add the images, and may need your help. PM later today. This should be all fixed up by this evening. Now we have room to add significantly more content to each size wheel. I didn't add an 18" section. :D

Here are the pics I sent to Victor of the BBS Mahle wheels 16X7" ET11 on the original lug studs. Thought you could use them with this wheel FAQ.

@rsporsche,

Clearing up any ideas about running 8x16 ET23. As video highlights, you still get rubbing with a 3MM spacer. This also means that an 8x16 ET20 with no spacer would also be an issue.

@Markos ... in 16" wheels, i an a proponent of 7" front wheels / 8" rear wheels. only in 17" wheels can an 8" work up front ... based on @vince experience. i have gone back and added a note to the one 16 x 8 et 23 wheel (style 5 - one piece) that it is rear only, and labled the 16 x 7 as front

Totally agree. You see these wheels on e9’s quite a bit. I’ll be buying some 6mm spacers. These are rollers and I can’t have them rubbing. The 225 tire also rubs the exhaust out back.

New 205 tires are too small for the car and the wheels are all wrong for an "L" but they don't look half bad. These are 15X7 ATS , not sure what the offset is. Tires were 225/50 15s all the way around with camber plates maxed out and cut springs. It's low....

@tferrer - 225/50-15" tires are almost 1" in diameter too small - only 23.9" diameter. here are the recommended sizes in 15" which more closely correlate to the 24.7" diameter of the 195/70-14" original tire

205/60-15 -– dia. 24.7”, width 8.2" / tread width 6.8", circ. 77.6”, rev / mile = 842
215/60-15 -- dia. 25.1", width 8.7" / tread width 7.3", rev / mile = 827
225/55-15 – dia. 24.7”, 77.7” circ, rev / mile = 842 <caution - tire is 9" wide - not many tires available in this size>
