Competition 4-1 Stainless Steel Headers by Titan Works

Good throttle response from 3,000-6,000 rpm

Front Disc Brake Overhaul

Front disc brake was leaking fluid so I decided to overhaul the pistons. Turns out that it's full of crud and rust from those years of use. I cleaned the pistons and cylinders and replaced the piston seals and dust covers.

Brake piston and cylinder ready for install.

Piston seal and dust cover installed. Used fine sand paper to clean off the surface rust and smooth out the cylinder walls.

Finished installing the pistons, brake lines, and brake pad lock. Drove the Fairlady around to test the brakes. So far no leaks on the lines and bolts.

Ready for some vintage racing action

10 vintage sports cars line up for the start of the MSCC Vintage Race

The busy pit lane as each category prepare for their practice sessions

The Fairlady was a bit twitchy at the rear thanks to the cool track temperatures and lack of grip from the Goodyear NCT5 road tires. A good upgrade would be the Yokohama Neova 185/60/R14 performance tires as pointed out by a fellow vintage racing enthusiast. Power-sliding was fun, but not good for the time sheets. The Fairlady was fairly easy to catch...predictable and progressive, but better tires are in order.

I'm thinking of changing to Hankook Ventus RS-2 185/65/R14 tires, since these are cheaper than the Yokohama Neovas but just as grippy. They even have a similar tread pattern design. Will definitely change to these for the next race.

Brakes were good as well and the cooling system held up pretty good. The set-up was really reliable for occasional track days and daily driving. Roll bar looks great too.

Some exciting vintage racing - 4 wide at the first turn

I felt like a winner...even in last place :)
