I did a search of this topic and the one with the most posts seems to be mainly about whether the X3 112 will fit in stock heads.

I daily drive my car and visit the track every now and then but not very often. I have an A4, will be getting 3400 stall with 3.73 gears. Which cam would be better for me?

 

I vote for the G5X3. I just ordered mine.

Good luck brother!!

x3 on a 112 similar setup to me, you will want more converter though

 

keep it coming guys. I heard that the MS3 is more of a top-end only cam compared to the X3. Is this true?

 

X3 is good from bottom to top and all in between.
Not sure on the MS3, other than what I've heard.

 

anyone else?
