There was no issue with clearing the suspension componenets with how Manu from Aritso Collection Designed the rims ( These are a very Agressive custom design ... Manu can be contacted if you are interested in the same set-up from Aristo Collection - http://aristocollection.com/ ... meaning he was not too keen on giving away the ET) ... there was a slight rub on the inner rear wheel well liners and a simple plastic body rivet was enough to get the liner out of the way and gave us a half inch of clearance in total from the inner liner and suspension components ... (Actually Mercedes did this as they dealt with Manu when he was the designer/partner at DPE for my last M6 and S63 AMG (Yeap ... even my last 2007 M6 was worked on by the PArts Manager at Three Point Mercedes with Manu Gill) ... Here in Victoria all the German brands are under one ownership ... BMW had an issue with the 325's actually fitting and had little faith in Manu, but Manu now from Aristo Collection and Sean from Three Point worked on my cars for rims hand in hand before, and now for the 2016 M6 worked on the rim design, tire selection and fitment and knew it would work (Manu himself has the M6 GC and worked on another Client M6 Coupe - but with 20s on them, and he used those cars to custom fit my 21s and fit the 325 rears with no rub on suspension components ... so the 2016 M6 was moved to Three Point to have the Rubber and Rims Mounted and the Rear Wheel well liner sucked back for clearance before it went to detail)

I now have 1100 km on it, thanks to a 3 year old birthday party in Nanoose Bay (300 km round trip) and even at highway speeds over dips in the highway at 120 km/hour and 2 kids in the back and gear - NO RUBBING

As far as the 335 goes ... I differ the discussion to Manu

Please share your driving experience with this setup. Also if you don't mind would you share the rear rims ET?

ONE THING I DID NOTE: with the 245s runflats up front, there was no shake in the steering wheel on slight ruts in the highway like had been on my 2007 M6 with 255/30ZR20s with runflats ... ride was smooth as well ... now this lack of shimmy/shake could be the total re-design of the current M6 .. but then again I do not have a 255 or 265 to compare too ... and I never drove the care on the stock tires and rims.

Anyone else have an opinion or experince with the shimmy/shake of the steering wheel ... my buddies with the last generation Corvette complained about similar issues with their runflats

It seems like you even have room to lower it as well. Cause I have KW V3's I want to close that gap, not going to lower the rear much just 0.5 if possible. What you think?

Yes we are running Pzero 325/30ZR21 runflats on the rear .. yes there is room to lower with how Manu from Aristo has set up the rear rim, however we did need to suck the inner liner in away from the wheel a little

And for sure you know that stock tires are not run flat? Both Michelin and Pzero tires are tubeless. All current M cars are the same... any specific reason you chose run flat?

I run a lot of highway miles to and from work ... first patient is 8 am ... can't be late due to a flat or blow out ...

Thank you for the information. I will make adjustments to my rear fender liner before we mount on the tire/rim. Because like I said, I want to lower the car enough to close that gap. If it wouldn't be too much to ask, would you mind sharing your front and rear offset?

You are welcome re the information. The Offset, however, is something you will need to take up with Manu at Aristo collection as this was the first one he did with this set up for 21s and 325 on the rear.

I definitely will, thank you!
