Hi guys , looking to fit cams to my M3 over the summer , which would be best for fast road ?

Also what are the pros and cons of each set , and how much am i likely to gain ?

My current spec is , CSL air box and tune , SS V2 headers , SS cats , SS resonated centre and SS LWR back box.

Thanks in advance.
