If they stay the same as the m3 with the z4m as they have so far with this kit then stage 3 570hp/380tq is $9,900! that beats ESS stage 2 by quite a bit $4,000 cheaper for more power!!! ESS does not even have there 550hp kit state side yet.
Hopefully this quality competition with create a more reasonable market for FI on our chasis...
