Ok, I'm getting ready to purchase a set of LT's from Calspeed, my question is should I run the 1 7/8" primaries or the 1 3/4" for my setup.
My currents mods are only a Custom Tune, Borla XR-1 and a Volant CAI. I plan to install a custom grind cam in about 6 months. Will the 1 7/8" primaries still be a good choice to run with the stock cam for awhile? or should I go with the 1 3/4"?
