Brake Set-Up: Ah I like my brakes and trying to find their limit. Installed new brakes last year from a kit put out by Milkfab. They use the early second generation 300ZX front aluminum 4 piston calipers with Honda soccer mom van Odyssey front rotors and 2011 Mustang rear calipers, with first generation 300ZX front rotors. They stop very well. Was finding that at marker #2 I could start braking going into the bus stop and still have some room.

Russ has owned the Datsun since the 1980’s. It was purchased through a friend in California, and then driven from the San Francisco Bay Area back to Orlando FL where Russ dropped off his friend. They completed the drive in just 2 days and 1 night. The car has competed in time trials as far south as SugarLoaf Key at the Bay Bottom Crawl, been as far north as Toronto Canada, ran Mosport, and has been as far west as Memphis Tennessee. This was even Russ’s daily driver in Puerto Rico while he was stationed there with the United States Coast Guard. In the last 30 years, Russ mentioned that the car has the original engine in it, which the previous owner said he rebuilt. Since then, the only thing done to the car was back in 1992 when the engine overheated. The car needed a valve job and head resurfaced. During this process, he discovered the pistons were from different engines and the #1 piston was “as rough as 40 grit sandpaper on the top”. So, he sanded down the high spots, put the re-surfaced head back on and “sent it”!
