disc brake conversion kits

I've got 4 wheel disc brakes from SSBC on my Barracuda. I did the conversion years ago when I was running my nitrous 360. The old drum brakes could barely slow the car down at the end of the 1/4 mile. This was at Bandimere speedway in Colorado where the shut down area is up hill!....scary stuff. I'm happy with the SSBC kit for my street/strip car. The car is faster now, and I can always make the first turn off with ease.
