If you want to go top-notch (and get stupid with your dough), I recommend a Baer setup. I ran a 4 wheel disc setup with a manual conversion for about a year before deciding to make it a drag car (replaced the HEAVY Baer setup with the LIGHT Aerospace 4 whl. disc setup).
The Baer kit is of the throw you through the windshield stop on a dime variety, and I have not tried out the Aerospace setup yet.
I opted for the front sport/rear rod&drag with slotted, cross drilled, and zinc washed rotors (excellent kit and VERY complete)
Here is a shot of the car before getting it fired up in 2000 (notice the lack of weight in the back due to no gas tank/gas)
How about those ridiculously LOW hanging Bassani headers, I went round and round with those guys to get a better set and eventually did!!
Was it worth the money? Man I hate to answer, but yes!!
I hope to say the same about the Aerospace...
