interesting because I had not heard that from z34 track guys - who, to be fair, may not be putting out the same power

I keep up with the E92 M3 crowd, and general consensus for the most part is the Giken OTS setup is great for track use. Some of that is because almost all owners don't really spend alot of resources to make much more power over stock, they focus on handling. Also, that car is tire limited really due to the body design. The exact opposite is true for the Z, most owners try to make considerably more power over stock, and the car can easily be over-"tired" due to the big body design. For the tire we can stuff under this car, it really needs to be making like 375 whp+. Not feasible for us NA track guys, unless you want to build a crazy 3.8L like the GT4 cars in Europe ran!

I've got a spare diff pumpkin just waiting to be rebuilt with a Giken for my M3, but just haven't gotten around to it. Knowing this though, I will certainly check into it before pulling the trigger for that car.
