Agressive fitment
Greeting folks!
After a long week of research from the forums, and using wheels calculations i feel confident fitting bronze Rohana RFX7 on a dark blue 2015 m sport 528i stock suspension new setup: the fronts will be 20x9 et20 with 255/35/20 tires the back 20x11 et 28 with 295/30/20 tires. My current setup right now is the 18x8 et 30 oem m sport wheels with 245/45/18 tires in the front and 18x9 et 44 oem m sport wheels with 275/40/18 tires in the rear. As far as my calculations rotational mass is close with a one-inch poke from old to the new setup. I currently have 1.75 inches of fender space right now so all calculations add up. what are your thoughts? I have not dropped her at all yet to make sure fitment is correct first. any tips and advice is GREATLY appreciated. I'll be looking to pulling the trigger on the rims Monday and the tires in 3 weeks. thank you again, team! |

You might want to recheck the amount of 'poke' you have on your rear wheels. My math says that your proposed rear wheels are going to poke over 1.6" further outwards than your original rear wheels. Before you consider offset, the rear wheel will stick out 1" further than the old wheel since it is 2" wider. Then, you add the additional 16mm reduction in offset, which moves the wheels 16mm outwards (approx .63") , and you will find that the outside rim of the rear wheel will move over 1.6" outwards relative to your original rear wheel. Your front wheels move outwards just under 1".

Thank you for your help, it means alot! Do you mind showing any pictures of your setup? Are you dropped at all? Do you think +33 offset might make more sence? I've seen some dudes run 20x12 with a 35 offset or a 21x11 in the rear with 35 offset. I wonder how they managed that..

Lowest possible offset depends on the tires, I now got Michelin PS4S 295/30, and under full suspension compression, they're just gracing the inner lining of the fenders, but not the fenders itself. This is not a problem with daily driving. Fronts depends how low your car is

All of the 21×11 were crazy really high at +50 or stupid low at +20. Shopping started off fun and now I'm just glad its over.. lmao You've been VERY helpful (I found some of your old posts) Very big ups to both of you! |

I know that feeling when you have a shipment of wheels on the way! That's freakin exciting can't wait to see them on. My entire build of my car took a few years whereas I see guys getting it done in 1. I have other things like family, house projects and other things that I have to work in the budget so take your time. I think you'll enjoy it more that way.
Good reviews with the Megan Coilovers from what I've seen. Look out in the MarkePlace for deals on coilovers by guys turning in their leases. Maybe you'll get a great deal on some KW's like I did. Not a fan of throwing Magnaflows on a BMW. I would look into the Remus Exhaust for your 528 with the quad design

I HATE the look of their exhaust tips. they look super small and bleh. How does it sound though??
the one above however look really good. maybe its beaouse its from underneath? i planned on putting down 2500 of mods here in the next week in addition to the Rohana's i already bought. if you can think of some good mods id love the input. the ride height and lack of decent exhaust note annoys the shit outta me. |
