FINAL 12" brake upgrade question to end all questions...

That seems to be the best bang for the buck. There are others
like Baer if cost is not a consideration. There is also the the G5
kit that eliminates the bumpsteer and ackerman problems that
appear with some of the 12" swaps. It uses 13" C5 Vette brakes
and spindles and has the adjustable upper control arm. Alittle
more than the Baer kit but you have your cake and eat it too. :)
