Best E92 M3 Power Pulley-Your help please!
I am looking to buy a power pulley package for my 2008 E92 M3 6MT and wanted your input on this. Whats the best setup/provider out there and which ones should definitely not be considered? Those that have them, do you feel and see true gains (dyno) based on the advertised numbers? Are there any drawbacks to the pulley system? Can it be recognized by the dealer and can it void your warranty? You help is much appreciated. Thanks.
