F82 Wheel Offset for Flush Fitment

[thenotorious_brz]

Hey guys, my apologies if this has been discussed already but I've looked all over and I can't seem to find anything in reference to my particular question:

I'm in the market for some new wheels for my F82. I want to run 19x9.5 in the front, and 19x10 OR 19x10.5 in the rears. Does anyone have any experience (and pictures, if possible) as to what offset will result in a flush fitment? I really want to avoid running spacers! Any advice is greatly appreciated!

Is this specific to the Apex brand or will the offset be the similar for wheels if I'm looking for a flush fitment (same diameter and width of course). The Apex SM-10 wheels are appealing to me but for some reason ET25 in the rear for flush fitment sounds too aggressive... hmm

It's similar for non-Apex wheels. This is a good starting point then you can double check once you've limited your options

Any pics on this setup?

19x9.5et22 + 19x11et40-44 with 265/35 + 305/30 or 275/30 + 295/30 tires. My street setup is HRE R101LW with 19x9.5et22 + 19x11et42 with 265/35-19 + 305/30-19. The pics are taken on a partially inclined surface so the front left and rear right are very close to what the ride heights on a flat surface looks like.

I also have two BimmerWorld TA5R track setups. One setup uses a front 19x10et25 with either a 5 or 7.5 mm spacer + a rear 19x11et44 with RE71RS or A052 with a max stagger of 20 mm, and the second set is a square wheel setup 18x10.5et36 with a 15 mm front spacer and square tire 295/30-18 square setup. I don’t have pictures of the track wheel setups except for design and color of the TA5R I use.

F: 19x9.5 + 21 (have a 10mm spacer on the fronts so effectively its a +11 offset now)
R: 19x10.5 + 22

E9X spec TE37SLs so more aggressive offsets.

Hope this helps

For the front, I’d be comfortable adding a 5 mm spacer (Turner spacer with integrated hub extender) to a 9.5et21-22 for a street setup but I doubt I could use a 10 mm spacer without having to run too much camber for the street. A 9.5et11 is close to the front track 10.5et21 setup which requires -3.5 to -4.0 deg of camber to get the top of the tire to tuck inside the fender.

How much rear negative camber do you need to run with a 10.5et22? The most common rear track setup is 10.5et36 with ~-2 +/- 0.2 deg of camber. 11et37 rubs with similar camber. The 11et37 frontspacing is 4.54” vs. a 10.5et22 with a frontspacing of 4.88”. The 10.5et22 has a 0.34” (8.9 mm) more aggressive frontspacing which is significant. What size rear tire do you run and what’s your rear camber and toe settings?

OEM alignment, I’m only lowered on Swift Springs which are a very modest drop, if I was on coilovers I’d go probably half an inch lower to get the fitment I want.

But OEM alignment
1.6 / 1.8 degrees camber up front
0.08 / 0.09 degrees of toe up front

1.8 degrees of camber in the rear with 0.14 / 0.13 degrees of toe.

It’s not that aggressive setup in my opinion, I never rub at all, even with my steep driveway.
