Anyone running 11.5" rear wheel
Currently I'm running HRE P40s in 20x9.5 et 25 front and 20x11 et 32 rear. 265/35/20 and 305/30/20 tires.
I'm selling my current M5 to a friend and will be picking up a 2015-2016 Comp Package M5. Since I'm going with the same car and with HRE's again (probably P101's this time) I was hoping to at least go with a little different size wheels. I really don't want to go with 21's due to many factors including horrible roads here, limited tire options, and less sidewall to hook up. However, I would like to try 20x10 up front and 20x11.5 in the rear. I know the 10" inch wide will work with no problems up front but will 11.5" fit in the rear? I was thinking to go with 20x10 et 28 up front and 20x11.5 et 35 in the rear. Pretty much both would sit out an additional 18 mm. I would run the same 265/35/20 and 305/30/20 tire setup. Feedback? |

Can't you just check the inside of the rear wheel well? I'd think it's enough room since I have 11" wide rears on my non M5 with room for at least 11.5".

Yesterday, out of curiosity, I have fitted an F15 X5 wheel 21x11.5 ET38 and 325/30 tire on my M5 and it seems that with a 305 tire it would fit. It's a close one definitely but the wheel was about 1cm from the shock and in line with the fender.

I have a 21x12" - had 305/30/21 fitted on it, no issues. I know 12.5" is doable with some really accurate ET measurements and tire combination.

Damn... Are you running K&W V3s? Not sure if V3 reduces tire clearance as it does for the F80.

Good news. There is a cheaper alternative to V3s. CKS coilovers have good reviews.

Only reason why I ended up going w/ H&R's is cuz I never had issues with them on all my previous cars, and by the time the suspension felt bouncy, it was time to turn it in... this time around, i still got a 9 or so months left and I drive the shit out of my car. :/ |

What was the offset? Maybe I will just let HRE handle the offsets to ensure it works out. I think 20x11.5 et 35 would work well.

Yes an 11.5" wide rear would fit but why would you? The only tire that can fit (without body modifications) is a 305. A 305 fits perfect on an 11". The wider you go the more you will be stretching the tire.

Anyone have more info on 11.5 or 12.0 rears for the M5 ?
Thinking of running 10x20 front and up to 12x20 rear with 305's I agree with going wider with the rim for turn in and feel |

11's would suffice and they would be less heavy also. +1 on the stretch comment also. |

Why do you want your gorgeous M5 looks like Honda Civic? There is a reason manufacture spec the 305 tire for 10.5"-11.5" not 12".

PS the width of the 305 PSS is 12.3 - 12.5 inches if I recall from the specs depending on which one, but a 12" rim will measure something like 12.8-12.9 rim edge to rim edge.
