I also need more power. however I also think that x-51 (specially retrofitting) is money thrown away. I am planning upgrade the same route with 3rd party pieces. After my warranty is out in 1.5 years, I will think of something major.

I am also coming from M3 and roads I believe are equally bad here. thats almost the reason I shyed away from S for a 4S.


regarding the topic. I am a car enthusiast and I apreciate what BMW does. The styliğng I am not used to but if it will have a lighter engine with 420hp+, my hats are off. M3s are very well respected in my book.
