    So update... I have added the BBK Massive Kit... and Arc-8 17x8... Looks like upfront I need a 25mm spacer... I have wrapped 235/40/17 on the 17x8, Toyo R1R rubber. Any recommendations on fender flares. I have Ground Control Coils and Camber plates as well... this is a E30M3 knuckle/suspension for other reference.

    Looks like the biggest you can fit under 15" Jonbloed would be 300x32mm / 11.75"x1.25" on all four corners ;-)

    Ding Ding Ding, Magic size.

    I have 205/50R17 on 17x8 M systems on my 318Ti daily, I would do 215's but tire choices suck and the stretch isn't that bad. I HATE Stretch

    Here early this year I will be seeing if I can fit 245/40R17 on Apex 17x9 et30 with Z3M suspension. Well see.. But will be the 250HP+ range. I'm thinking this will be needed. I don't want flares, I hope I can keep factory body lines.

    • Available in ARC-8 design only.
    • Requires front negative camber.
    • Requires 5mm front spacers for brake clearance.
    • Requires rolled rear fenders to prevent rubbing.
    • 235/40-17 tires can also be used, but more negative camber will be required.

    We would not recommend the 245mm tires on a 3 series. The E30 M3 benefits from fender flared arches that allows for much wider wheels and tires, and while the E30 M3 suspension kit does aid in fitment, we would not recommend M3 fitments on a standard 3 series.

    I hope this information was helpful. If you have any further questions, feel free to reach out to me!
    I have 215/40/17 Falken Azenis on my 17x8 and they're stretched.
    No way I'd put a 215 on an 8.5" wheel.

    I have E30M3 Suspension 5-lug, with Ground Control Coilovers. Hoping to not have to cut the fenders. Already rolled, but not apposed to modifying more, just prefer not to cut. Question is more about tire/rim sizes. Would like to use the A052, but they are only available in 245/40/17 or 215

    I have 225/45/16 and happy with overall performance... running A052 for AutoX and R888r for the track.

    Looking at for AutoX
    Proxes R1R - Size: 235/40ZR17
    ADVAN Neova AD08 R - Size: 235/40R17

    Track:
    Proxes RR - Size: 235/40ZR17
    Toyo R888r, 235/40/17

    Better to buy the 17x8.5 Profile 3 or 17x8 Profile 1?
    Concerned about the backside of the tire/rim and having to add spacers.

    For HPDE I run the ARC8 four lug ET20 wheels with 235/40/17 BFG Rival S square on a 1987 325i. Suspension is H&R race springs with Bilsteins, camber plates. Fenders are rolled and the liners have been removed. For the street I run 235/40 Yokohama S Drive's square, both sets of tires are very close to rubbing on the strut tubes up front but do not, no spacers used.

    215mmm tires on an 8.5" rim will stretch the tires' shoulders. Not a good idea. As we discussed over past emails, here's my recommendation in term of rim width vs tire section.

    8" rim - 225 to 235
    8-1/2" rim - 235 tire
    9" rim - 245

    The 17x8 has diff front face allowing better brake spacing.
    But then the tire sizes are at issue.
    Other wheels that are recommended?

    Ask Apex about it. They are very knowledgeable and helpful folks.

    I have 17X8 over Massive Lee 300x22 kit and they fit fine, with tons of room. Another guy has the biggest kit Lee makes, the 332x32 kit under the same wheels.
    As far as using spacers, not sure. I'm running into my swaybar with 205/15's and ordered 10.5mm spacers from ECS.

    Fenders aren't rolled or anything though.

    Interested in the AD08's
    I've heard awesome things, but the life isn't as long.
    I'm a long time RE71-R fan, but I'll see how those do this season.

    It's going to depend a lot on the size and profile of the tire you select, how much camber you run, and how low/stiff your suspension is.

    I'm making the same move soon, 17x8.5" ~ET20. I plan on running 235/40-17 Nankang AR-1's. Coming from 16x8" ET18 with 225/45-16 Dunlop ZIII's.
