Widebody time
I’ve pulled the trigger on a set of Moshammer flares and will be getting them Installed over the next couple of weeks.
I have already widened the rear (metal pull and repaint) by an inch or so on each side: which allow me to tuck 295’s out back.
ideally I would like to step up to a 325 section width tire out back. For those of you with rear wide bodies, what kind of tire / rim sizes are you using.
I love my current HRE P43S’. But I don’t think they will work with the new wider fenders.
narrowed down rim choices to BBS Fi-R or HRE S101.

Do you still have the white C63 sedan?

1. there is not a lot of space to graft near the fuel door
2. sedan is much harder to mould in vs coupe, due to rear door panel
3. recommend black series fender liner (will require some modification), otherwise get underside sealed properly
the wider wheelbase will transform the rear. What size wheels are you thinking?
edit: i am running 11.5x19 et30 rear. 305/30 tyre. Can fit wider but no point, if you cant hook with 305 u have other issues tbh.

Thank you Jorge, appreciate you my friend.

Where did you get the BS liners from? Was thinking about them or simply adding a flexible carbon fiber band riveted to existing fender liner. My car is widened already so i had to address it this way.

Worked out some of the fitment numbers with Mort on here through PM, he has the HMS flares which i think are similar in clearance compared to the HPC's.
Are you poking in the back? Its not lowered much is it?




Im thinking 20 x 11.5 ET 35 Rear. i know a 305 / 25 / 20 would work and oddly enough its actually cheaper to buy 20 inch tires compared to 19's.

no not much lowered. Remember u will gain clearance when u cut the wheel arch. Im moving to 305/35 tyres next, so that will eat up the gap more
Also if I were to go back I would not get HRE. Wildly expensive and there are some isolated but troubling reports of failure on high power w204 c63.
Being facelift saloon, the Moshammer kit did not fit as the rear bumper piece was not wide enough in terms of the side groove, thus alignment was all wrong for the rest.
The build is blogged here.

Rear wheels set up currently 19x11.5J ET30 305/30/19
You might struggle to fit 325 if the coilovers are dialled too low.

You and i both know as special as those 911's are. The C63 represents awesome value still, I sank too much into it. After 10 years, no sense of getting rid of it now. I just think, in 10 years from now.... How quiet things will get with Electric cars more common on the road. Makes me appreciate the C63 just a bit more... I think we all knew they will become a cult classic when we bought them, especially the OG members on here. Just a few of us left now

I like the wide rear conversions on this car, I just dont care for crappy body work and bad paint and sanding ( AshBNE's car has horrible gaps I can't sleep with, no offense Ash). Make sure they do a tight job with crisp lines because your car looks so OEM perfect.

Matt! yes my friend, after such investments into it I don't see the need to change it I only drive it a few months out of the year during summer. Really there aren't many cars that gets my attention, very few newer cars have character. Too much electronics for me.
