A RennTech powered Mercedes SLR, title the L4P SLR777, set a new quarter mile world record time for a Mercedes powered Mercedes-Benz.  The L4P SLR777 did the quarter mile sprint in 9.76  seconds at 140.8mph or 226km/h. The L4P SLR777 project is a team collaboration project between Platinum Motorsport, RennTech, MACarbon and Exotics Boutique.

The L4P SLR777 is the only Mercedes-Benz McLaren SLR with Mansory Renovatio bodykit installed outside of the Mansory Factory.  Back in October, the SLR completed the quarter mile in a mere 10.29 sec at 134mph. The new time sets the bar for competitors even higher and reconfirms the statement that this is the world’s fastest SLR.

Platinum Motorsport, RENNtech, MACarbon and Exotics Boutique partnered together to create the world’s fastest SLR, running the 1/4 mile in a mere 10.29 seconds at a speed of 134 mph. Nicknamed the L4P SLR777 it is the ONLY SLR with a Mansory Renovatio Body Kit done outside of Mansory Factory. Platinum Motorsport finished off the exterior of the SLR with a very special new Liquid White paint. MACarbon was contracted for all the custom Carbon Fiber interior pieces, and Platinum Motorsport finished the entire interior in black suede and fitted the car with custom 20 inch Agetro M140 Monoblock wheels.  For those of you that want to see the world’s fastest SLR in person, it will be making an appearance at this year’s SEMA Show.

Custom Front Hydraulic Lift kit with Remote

-The HLS 2 (Hydraulic Lift System) provides additional road clearance for lowered vehicles by raising the front axle suspension via the push of a button. When expanded, a range of up to 45 mm of lift is produced, thereby helping sport cars avoid road clearance difficulties such as speed bumps, road construction, etc. The system contained within the rear of the vehicle and is actuated by a push button on the optional remote (there by eliminating the need for any interior wiring).

RENNTECH Mercedes 722.6 Five Speed Transmission upgrade

-With increased engine performance it becomes necessary to further improve the drive line components, most importantly the transmission in order to ensure maximum power is transmitted to the drive wheels without transmission slippage. This cannot be realized with software and only truly be accomplished by an internal mechanical upgrade to the transmission hardware. Our upgrade leads to improved shift response, shift timing and greater drivability under extreme conditions without sacrificing around town comfort. Our mechanical upgrades provide years of trouble free operation and have been tested to in vehicles producing over 800 hp and 1000 lb/ft of torque. The transmission is reassembled using all new gaskets, seals, o-rings, electrical connectors as well as a new transmission pan filter.
