S3M 263 deg 11.6mm

I've talked to JWT about this, i'm wondering if someone just put S4's in a GTIR motor. 3 deg wont make much of a difference in power.

He's wondering about the S4M cams. Free bump for an answer.

the 'm' in s4m should only designated that they're for use with the mechanical lifters, hence the gti-r motor. Therefore, they're still S4s so they should still be street cams and therefore not require springs, etc.
