Right, I've taken in everyones opinions and also a fair few from the US AMG forum which has hundreds of C63 owners giving their advice....and I've had 2nd thoughts on this Brabus upgrade.
Also, a company in the UK has come highly recommended by someone I know - Car Planet Racing (CPR) in Warrington.
CPR just happen to be the UK's Kleeman distributor and pretty much only AMG specialist. Kleeman is a massive Dutch-based AMG tuner who offer 4 levels of tuning for the AMG '63 engines. As said before, one of the main reasons I wanted Brabus was for the fact they are Mercedes approved but after some research, it appears that Kleeman are available to buy directly through Mercedes dealers in the USA (very much like Brabus is over here). So, I've just called a dealer over there (pretending to live in the States!) to find out more and it appears that they are indeed approved by Mercedes in the States.
Now, I know this won't cut any mustard over here but TBH, if it's good enough to be offered through Mercedes in the States, I'm now more confident that the product is going to be just fine!
So, I know it isn't Brabus (and I don't get those iconic badges

) but it is 1/3 of the price! Therefore, I've decided to go for their K1 (most basic tune) which gives 525bhp. Their other 3 tunes involve changes to the exhaust, the manifolds and the throttle bodies and can give up to 600bhp! However, I don't have any desire for anything more than just getting the engine to the output it's designed for and I don't want to change any part of the exhaust as I like that just as it is!
I've also spoken with CPR to discuss this as well as some other thoughts on my car concerning the handling and brakes.
Firstly, my new one suffers from (a bit!) more body roll compared to my previous C63 (the older Performance Pack had stiffer suspension that's no longer available on the new PPP one).
I've considered having the suspension components from the old '08/'09 model C63 PP fitted - this would give me the same ride/handling as my previous C63 but given Mercedes charge over £1k just for the bits

, and after some advice from CPR, I've decided to go the full whack and get some KW Coilovers for it.
According to the AMG forum in the States, this is by far the very best upgrade for the C63; it keeps the ride about the same as standard and totally flattens the handling (and they are also fully adjustable). They are KW V3 Coilovers and they are the exact same units that AMG fit to their Black Series cars - CLK63 Black and SL65 Black (confirmed to me by AMG themselves).
Too good to be true??

....well I don't know as I've never experienced Coilovers but if they're good enough for the Black Series models then they're good enough for me!
Finally, a rather small upgrade but I'm also having braided brake hoses and uprated brake fluid - the brakes on the car are astonishing (6 pot front, 4 pot rear Brembo's) but there's a lot of pedal travel. This small mod should hopefully eradicate that.
So, despite not being so mad in getting the Brabus tune, most of you will probably still think that I'm just a crazed (and possibly stupid!) nutcase!
Oh, that'll be my car totally done....finished! Honestly! It'll hopefully be set up nicely for my trip to the Nurburgring (my 4th one so far) in August.
Right, I'm off to drive to Germany in a couple of hours and will be car-less for the next few weeks!
