The website for Sprintbooster does not make you specify between r56 and r53 when ordering, and i found a sprintbooster from an r56 for a very good price, I searched and couldn't find anything, does anybody know the answer? Thanks.

 

I think it's all the same... but there was a difference for the Automatic and Manual trans. Let me know how you like the thing... I decided to save the money and just hit the gas harder and downshift.
