So lets finally start this project thread. I'm now the 3rd MBClub Member to own this E55, and what a hell of a car. Miles are adding up, but this car has had at least 3 owners that have provided everything this car could possibly want. To recap, performance mods include an 84mm supercharger pulley, split cooling with front mount tank and bigger heat exchanger, X-pipe with secondary cats and resonator deleted, and rear back boxes I think are gutted too. I have since added a TCU tune, which I highly recommend. Car also has some carbon trim, blacked out grille and lowering module. This car came with a huge amount of history, clearly showing previous owners that were able and not afraid to spend what needed spending. I myself had to drop a fair chunk of change to rectify a few age related things that are needed on a 100k mile car. Including: All new front brakes + fluid Levelling sensors Prop shaft coupler Belts Filters Oil change All new tyres Top and lower ball joints, plus other stuff I've forgotten All work done at Autoclass in Milton Keynes. Highly recommended. Steve is hugely knowledgeable, came highly recommended and I can see why. He had several other AMG cars there, including an SLR. I put a wider tyre on the rear, a 285/35/18 to replace the factory 265/35/18. I went with Yokohama Advans, and I'm pretty happy with them. The jump from 265 to 285 made a very noticeable difference in grip under acceleration. With the 265s, they would light up easily at any speed in 2nd gear. Now they hold MUCH better in 2nd without spinning much at all. Fantastic. Also got the alignment done at Wheels in Motion in Chesham, again massively recommended. This brought the car, effectively as mechanically perfect as I could get it. Very happy, and a great starting place.
