Roller Rocker Arms. Steel or Alluminum
Roller Rocker Arms. Steel or Alluminum
I'm going to put on a set of 1.6 rr's on my car. I was wondering will the lightweight ones add anymore performance? Or will they just last longer? thanks for the help

I went with comp pro magnums. they are steel and claim to be less weight then the AL because of the smaller design.
