[Flash68]

I have done a search on this site and a couple others and really couldn't find an answer, and I can't really figure out the big difference from the language on Centerforce's website either.

Any insight? thoughts? recommendations of these 2 models?

I will be running between 600-700 rwhp, depending on pulley size I use, but will use street tires and a TKO 600 for street driving only... no 4000 rpm launches with slicks for me... at least not for now.

thanks
