    Purchased a Z3M 5 lug, need wheels!

    Hi guys,

    I need help with wheel selection for my E30. I got a great deal on a complete Mcoupe subframe, diff, brakes, trailing arms etc., and front brakes, strut tubes, control arms etc. I'm a 4 lug guy but, I keep breaking my half-shafts, so I've been forced to go 5 lug/ Mcoupe rear end. I have the THR racing CAB's. Can I use them?

    I'm looking for wheels, I believe high Et will work. I've looked at and thought about running DSII's but, they are heavy. In a perfect world I'd like to run 15's but I don't think they'll fit the front brakes. I know Otis has squeezed 15's over the rear Mcoupe brakes and I'd be willing to do that also.

    That said, and if possible, I was thinking maybe 16 or 17 style 5's up front and 15" style 5's in the back. That would allow me to run more sidewall in the back but, not sure it an et20 or et22 would fit in the back. Any ideas?

    Second COA would be to run a 17" set up all around or 16's if they'll fit over the front brakes. I need to run aggressive drag radials in back too, which limit wheel size choices.

    Anyone have any wheel suggestions or recommendations? FYI- front and rear fenders have an aggressive roll too.

    Thanks,
    Ryan

    16" e38 style 5s are nice and light and cheap. Have never been unhappy with them on e36/z3 combo 5-lug, even for a moment.

      What are the Et? Will they fit the Z3M rear?

        16x8 et23.

        You'll want to verify this, but if memory serves, the Z3M hubs sit inboard of the Z3 1.9 setup, which is what I have.

        I don't think you'll have clearance issues. You might even have room for more, but the e38 weaves will bolt straight up where e39 wheels need hub rings.

          Sounds perfect. Do the 16's fit over the M3 brakes?

            I read that they will fit over the E36 M3 brakes. I just bought a set so... I hope they fit. LOL Anyone have any other ideas or recommendations. Also, what is the et of the 15" style 5's... I may just mount slicks on a set of 15" style 5's.

              I had the 16" style 5 wheels on my old 5 lug E30. Also running the E36 M3 & Z3M combo. My fenders were heavily rolled and slightly pulled and I still had rubbing issues in the rear with a 205/50 Falken tire. I also had a rear camber correction kit installed which of course didn't help fender clearance. When I ran my 17x9 ET42 ASA AR2 wheels I had a 245 tire on them without rubbing.

              To answer your other question: Yes the Treehouse CABs are a good choice with this setup.

                Thanks for the info. How low are you?

                My current set up is the Apex 17x8 Et35 wheels that I added 1.5" to the inside of the wheel. I run a 20mm spacer and a 255 or 245 tire. It rubs are times but, not too bad. My quarter is rolled and pulled as much as possible etc. so, hopefully the 16x8 work! Do you remember how much room you had on the inside of the wheel/tire? I was thinking about having an 1" or 2" added to allow me to run a 245/ 255 drag radial.

                Here's are a few pics of the car/ fenders:

                    Spoke with the shop in the video above, they said they can safely remove 7-8mm from the wheels. So, that would raise the et to 30 or so. That should work better, no?

                    How about the front. Should I have all four machined or just two?

                      Any opinions on et35 wheels? Will they fit a decent size tire without rubbing?

                        I managed to fit these (slightly f-ugly) E39 15's over the MZ3 rear rotors.
                        NB. I use a 996 Monobloc 4 pot caliper, can't imagine it giving more clearance than a stock caliper.

                          Thanks for the info. I think I'm going to try the suspension the way it is. I have an aggressive roll/pull so, we'll see how bad it rubs. That said, I sent pictures to the guys that machine the wheels. He said they can remove 8mm of material once they reinforce the lug holes with steel inserts.

                          From what I've read, the Mcoupe stuff is 20mm wider than the E30. 20mm= .787"
                          8mm= .314"

                          That leaves .473" difference. Worse case, can move the training arms inboard .500" and be around the stock E30 width. I'll have to look but, i really don't think .50 will affect much... mtf

                              I have 17x8 BBS Style 5's (RC090) ET 20. 5x120. The set has been completely disassembled. All paint stripped off the centers and all clear coat stripped from the barrels. includes 4 center caps, all hardware, and of course the cap removal tool. PM me if you're seriously interested.
