Quaifing the C63

[ecain63]

No idea to be honest. Its a 2010 pre facelift so im not sure.

If money was a factor then maybe not. Its not worth being skint for. However, the differences although small do add up to something noticeable and beneficial so yeah, id do it again. Even at £1600 its still a cheaper and better mod than speccing the oem diff.

Yup, I fully agree with that. It is more progressive on the slide and generally feels more planted. In a way the car feels heavier, but not in a sluggish or negative way, more that it feels solid and predictable. As a result the car I'm sure is a tad quicker point to point and I feel much more able to chuck it round the bends without worrying about the traction control reigning me in prematurely.

Im finding the quaife to be a huge help currently with the weather being so damp. Glad i did it!

Factory diff offers circa 30% lock. The Quaife diff offers up to 80% lock. Result is that the Quaife is a bit snappy when letting go but it does offer better traction.

Good show mate. Go forth and enjoy.

Honestly, its just different. The C63 is quicker, more fun and more usable, no doubt about it, but the M5 was a more refined and more involved drive. If the C63 had the SMG box itd be fantastic. If the M5 had the 6.2V8 of the amg itd be perfect. As they are both are just different.

Oh, I think the C63 is a quicker car now thanks to the quaife. Been out in it tonight and Claire actually cried as we fired out of the exit of a local roundabout. 100% of the power was there from the off and the push coming through the apex was a definite increase on what was there before.

Its early days but I think I may be converted.

Did you like the SMG box of the e60 M5 V10 better then the gearbox of the C63? I'm personally thinking of buying a C63 AMG 2012 facelift…but the gearbox is something I'm not sure about. Still I did not like the SMG box in the M5 V10. I found it really annoying in manual and auto mode in traffic and it was only enjoyable when going fast on open roads or highways… Also it seems the SMG gearbox has a lot of issues with some owners.

I think the SMG box clicks with some people and not with others. I really liked it and am of the opinion that if the C63 had the option of an SMGIII box to go with the big V8 it'd be the ultimate weapon. But not everyone would agree and it really depends how you use it. Of all the vehicular gadgets i've had, the M5's box and the C63's engine are the things i miss the most.

Did you hate the C63 gearbox….or did you find the SMG V10 box more of your taste and you could also live with C63 gearbox…?

I found the C63 box perfectly adequate. Paddle shift wasn't that special but the auto modes were quick enough for 99% of applications. I think the different boxes are supposed to be learned rather than liked from the start. The facelift C63 box was quicker by all accounts but i'm not convinced it was better.

Another key point is that the experience will depend greatly on the roads on which you spend most of your time. I spent much of my time on national speed limit roads so the cars were in their preferred zones most of their days. If the M5 was around town all the time it'd be a nightmare. Same as the C63, if it spent all it's time shuffling around the streets of London i reckon i'd be fed up within a couple of months. These cars are designed to hammer the autoroutes and will behave better in that environment. I've since moved on to a modified A45 and can say whole heartedly that it's perfectly happy around town and on the back roads. For a 4 pot turbo / MCT box combo holds it's own on the motorway but it's not at its happiest there that's for sure.
