Congrats on your new purchase. I purchased my 03 CL600 in August 04 and absolutely love the car. I put the RENNtech upgrade 3 kit on myself and have been nothing put pleased with the outcome. If you go back to the track let me know what times you get.

Before electing to invest in the RENNtech upgrade, I reviewed the feedback that others give on their upgrades compared that with other kits and finally spoke with Hartmut Feyhl directly. The 600’s (SL/CL/S) that have been dyno’d produced 500 to 530 HP at the wheel. Based on the type of transmission in these cars it makes sense that at the flywheel the V12 is producing 625HP given a 18% to 20% efficiency loss. Here is a link that has some very good discussions on the upgrades. https://mbworld.org/forums/sl-class-r230/60870-sl55-sl600-differences.html

Just got back from the track.This is the first time I have run it after the Renntech mods..My best time with little traction from the Michelins was 60ft 1.82 and a 11.64@119.92MPH..Not bad,but with just a little traction I feel I could get deep in the 11's.With me in the car it weighed 4745lb.I weigh 220lb.My best previous time was a 12.24 so it was exactly 6ths of a sec faster and approx 5mph..
