Driftit 2124 Report post Posted February 14 After reading that Nowack Tuning Report... wow. Are we not looking at this the wrong way around? This isn't a M5 that has been re-shelled. It is a base spec 530 that's been repowered with 23 year old, heavily modified M5 running gear. 2 Quote Share this post Link to post Share on other sites

This seems utter nonsense. US$50000 for 100hp. Couldn't he have bought a supercharger kit for 1/4 of that and got more than 100HP and still had factory reliability? It makes no sense. 1 Quote Share this post Link to post Share on other sites
