All pro's vs an open diff. No Con's.

Difference between the two diffs are the wavetrac will keep the axle spinning under zero load conditions, ie if you lift a wheel the wavetrac can still deliver power to the wheel off ground.

Personally I don't think most people would ever know a difference in either diff they both perform amazingly even over the stock LSD in performance package cars.

I honestly don't have any data for a in increase 0-60 or anything like that for the SLK55 but I can guarantee you going from an open diff to a LSD is one of if not the best modification for any AMG or high performance rear wheel drive vehicle.

Traction is the biggest issue as we all know so the more you can help deliver the power to the ground the better suited you are to maintain control of the vehicle and improve lap times or ET's.

Adding power mods is only going to exacerbate the problem truthfully which is why for most M113 55k or M156 63 customers I recommend this even before doing an ECU tune, headers or pulley.

One of the best mods I have added. In addition to the traction, also makes long straight burn outs easy!
