I agree with Omegabenz. My C43 is a great car. The engine is incredible -- a lot of low end torque, great highway cruiser and even a back road burner, but always very comfortable. The only real performance mod I performed to the car was lowering it about 1.5 inches with H&R sport springs -- these springs improved the ride and the handling dramatically. (H&R's are stock on a 911 I believe). The progressive H&R's complement the car nicely and smooth it out at low speeds on less than perfect roads. At max speeds the car is always as smooth as glass.

I really want to have a Kleemann installed -- that will give the car about all the power it could handle: 450 hp and 0-60 in about 5 sec's; quarter miles in the mid to high 13's.

I envy your dilema.
