    I'll be running ~400hp+ so will need as much grip as possible, thus the 245 R-comps. Would 235 fit without a spacer?

    Thanks!
    I can't see a 17x9 +40 fitting without spacers. A 17x10 +20 (wheel only, no tires) clears the trailing arms by a few hairs, and the 17x9s would be 7mm closer. Hence why I suggest 10mm spacers.

      I'm looking to push the rear wheels out a little bit so they aren't so tucked. The wheels are 15x7.5 et 25 with 205/55R15 tires. I'm on Billy Sports + H&R Sports with both rear spring pads.

      Will I be able to get away with 12mm spacers and rolled fenders? I don't want to do any further fender work, but wouldn't be opposed to rolling them. From what I've read 12mm is the minimum width that are still safely hub centric.

      That would theoretically be the same as a 15x7.5 ET13 wheel, any idea if that fits an E30 (late model)?
      Very tight fit. With 205/50s it would be fine, but I think it might rub just a bit with your existing tires.

        ROTA WHEELS - GRID_V

        15X7"

        Bolt Pattern 4X100mm

        Offset 20 mm

        Lip Size: 2.2.5"

        Hub Bore Size: 67.1 mm

        OR

        Some used Volk wheels I just found nearby

        16x7
        Offset 42
        Hubbore 73mm


        I'm a total newb, so whatever I'd need/to do to make these fit would be much appreciated
        The Rotas bolt right up, just need hubcentric rings (67mm - 57.1mm). Use 205/50, 205/55, or 225/45 tires.

        The Volks require 20mm spacers all around as well as hubcentric rings. 205/50, 205/45, or 225/45 tires all fit.

          I think you're spot on, I have 17x9ET22 with a 245 currently and it barely rubs the inside of the rear quarter (late model) under compression. Maybe 15mm spacer with 235's, that tire size seems to be getting phased out though, you can get everything in 245 but it's much taller

              Before I go out and drop any cash, just would like to know whether the Volk's (16x7, Offset: 42) with the tires you mention would require fender rolling (I run billy shocks & HR springs both sport)?

              Also, if anyone has pictures of a similar style set up, I would love to see!

                Thanks for the info. I might go ahead with 17x8 +20 all round then, with 215/40 front and 235/40 rear. That should fit without issue I understand.

                  100% won't rub with the 205 choices, won't rub 99% of the time with the 225/45s and no rolling.

                    That will most definitely rub in the back. +25 is the key rear offset for 17x8 235/40.

                          Not a fitment question, but a grip question. Currently running 205/45/16 s.drives on my s52 swap. Going to step down to 15's plus meat flush for sake of dd'ability. Unfortunately it seems my only options are either 205/55/15 or 225/50/15, the latter of which only comes in kumho ecsta ast's. The 205/55/15 options are alright but I know grip wise, it's going to be the same as what I already have. I'm not willing to go undersized at all.

                          So the question is... grip wise... 205/45/16 s.drives vs 225/50/15 kumho ecsta ast. I'm pretty sure I know the answer to this (kumho ast's suck), I'm just always down for a surprise. These would go on a 15x7.5" btw. Thank you for any advice.

                            Now that Toyo added a tire to the short list of available 245 / 45 / 16s for the road I'm stoked on getting a set of 16x9s and getting a set of those tires for road and track. I'm running IE3 springs with all of the spring pads and no drop hats or anything + Konis. I plan to add camber plates and fender flares. Can I keep the offset of the wheels close to +20 ish and how much would I need to attack the front fenders for vertical clearance?

                            Thanks!

                              I've seen these run before, but it is an extreme fitment. You will need rolled and maybe slightly pulled fenders, especially the rears. 205/45 all around.

                                You will need 12-15mm front spacers and stretched tires. At H&R ride height I think it would look really bad. Only way to pull something like those off is with mega tire stretch and the car slammed to the pavement.
