Hi @
CSG Mike, this is quite the thread you have going here.
I have an 86 with no power mods, but I'm considering upgrading to a BBK. My local track is hard on brakes and I have the budget right now, so I figured I might as well.
I have the option of going with semi-float or full-float discs. As far as I'm concerned, both are probably more than ample performance-wise. I just need to deal with the heat, not necessarily stopping power or braking feel. Therefore my main concern is long-term running costs and street performance because the car is my daily.
So far I am considering going with semi-float, because in my mind less moving parts = less maintenance. Would you agree that this is a good idea? The larger discs are pretty much guaranteed to sort out my heat issues, so I don't need many other benefits from a floating assembly. What's your opinion?
