brake kits that were adapted to many vehicles. One signature look they had was very dense cross drill pattern on the rotors. Like Bernie says, they were one of the first big brake kits (after the Skyline upgrade) that was used on the Z32 and sold by Stillen.
I'd check Zeckhausen Racing like vorpalZed says. They used to sell a lot of Brembo stuff. I got my Brembo GT kit from Horsepowerfreaks so you might also check with them.
