Blazer and LS1 swaps are swapping the brakes from a Blazer or Camaro (forget the years, but a search will do you wonderfully) onto your TR. Some have told me that the engineering behind the ls1 is "iffy" (I can provide you with the science/engineering behind that notion if you message me) and on the contrary tons of people are doing it (sound like I'm trying to get you to smoke weed lol) anywaysssssssssssssss
Stock rotors are 10" dia. Gbodyparts dot com has a stock replacement 10.5" dia rotor... I'm looking into the dual piston calipers from Performance Disc Brakes from Stainless Steel Brakes Corporation (SSBC) as the stock are only single piston... which is a no-no for our cars' torque and power!!
As you probably know, there are 3 "major" TR forums.... I personally use this one for suspension, brake and turbo info.
