Unleash the supercar within. Then hang on. Unbridled power is what our turbo kits have always been about and this ones more of the same. A lot more. Like, say, double the stock 240 BHP your 95 M3 was born with. Yet for all their brute strength, these 480 Active Autowerke horses are remarkably well behaved. Delivering the smooth, effortless civility of a daily driven car that just happens to be possessed by the throbbing soul of a supercar. This 3rd generation design also features refinements in boost control and reduced compressor surge. With 480bhp and 460 lb-ft of torque, it was like being hit with a sledgehammer, slamming my internal organs against my spine¦ Even a moderately tuned Active Autowerke Stage 1 kit made me wonder if those factory binders were big enough. Stage 2 made me certain they weren't.
