Same! After this length of time I'm unlikely to bugger off. The fact that the info you get on here is usually better and quicker is a bonus!
@Sir_Dave has had both as dedicated track sheds so can offer a pretty good idea.I have recently been looking at these R53 MCS's to replace the clio trackcar, still weighing up whether to do so or not
I've briefly touched on the differences in my thread here: http://www.cliosport.net/threads/another-mcs-the-track-day-toy.755737/@Sir_Dave it woulds appear you are the fellow to offer some advice on the comparison of a clio or MCS as a track car
Handling wise, in the morning (damp) on the Continentals (Meisters set to 17fr/9r), the car was incredibly playful, good front end turn-in, but the ability to steer on the throttle whenever i wanted, oversteer on demand basically. Perhaps not the quickest way round the circuit, but certainly epic fun!! Myself & Tom were quite simply driving around giggling. Turn-in, lift, oppo, power. Brilliant!! In the afternoon (dry) the R888's went on & the rear dampers were turned up 2 clicks (now at 17f/11r). Compared to the morning, soo much more grip, incredibly turn in, at any speed, similar properties to previously re: LOOS but obviously at much higher grip thresholds. It was genuinely rapid.
Only issue all day was the brake pedal went a bit long (Minispeed didnt use the high temp fluid i gave them), so they need re-bleeding before the next trackday. Actual braking power was superb, there is simply no need for anything more than R56S fronts with XP8's imho, no fade at all, even after some seriously late braking lol.
In conclusion, i think ive now created something better than my beloved Trophy, the handling is the same (if not slightly more direct steering wise) and it has the power to overtake things that would previously have held me up on the straights. The extra bhp is also very useful for straightening the car up when staring out of the side windows.
