Scarebird Conversion

I have done a TON of googling and I think I've found all the threads possible about Scarebird kit and other than some people finding some problems with having to grind some extra off their calipers and one guy saying his bracket broke its been mainly positive reviews. So before I pull the trigger on doing this conversation does anyone have any recommendations for any other kits that are similarly priced? I've heard some talk about kits from Classic Industres and Mancini but they are both about double what I'm looking at spending on my Scarebird kit ($350 with drilled and slotted rotors).

Right now the car is /6 but I'm planning on putting a 440 in the car down the road. The plan right now is its going to a fun street car that may see a drag strip once in a blue moon. I'm mainly looking for a little more braking power and less brake fade in case I have to make more than one panic stop while driving around town/at shows. Not trying to break the bank hence why I'm really looking into the Scarebird kit.

BTW... I want to stay with the 5x4 bolt pattern.

Thanks for your help!
