Glenn Chiou is an avid Datsun enthusiast having owned and raced several cars. You might remember his VIPS 240z vintage race car from the The Mitty and Rolex Monterey Motorsports Reunion events. He also races a Datsun 510 B-sedan and owns a Nissan R32 Skyline GT-R:
This 1972 Nissan 240Z-L however is “the list” car for Glenn that started his Datsun passion. Glenn has owned it for several years, enjoying it as a back-road burner on the street and rallye events.

We’ve known Glenn for many years and we actually tuned his Fairlady back in 2012. The 3L stroker produced one of the highest dyno numbers we had seen!
Big Brakes for Glenn’s S30
The Z clearly had more than enough power, but braking was always something Glenn wanted to improve and once he heard about our latest Big-Brake Kit for small wheels he became a believer after test driving them. Rather than tell you how we feel about this product, let’s hear Glenn’s experience.
Throughout my years of Z car ownership, I have run a variety of brake setups. My Z cars have seen everything from restored OEM Sumitomos, Toyota 4×4’s, trick Wilwood setups, even frankenstein’d Baer calipers. There is no doubt that it has been one area that I have never been completely satisfied with. Over time, after many years and attempts to find the ‘perfect’ setup, I had given up and just settled for what I had.
The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me. On my vintage 240z race car, we use multiple master cylinders, swap them in and out, fiddle with our brake proportioning valves, fine tuning them to fit our driving style and preference. We are trying to find that “racer’s edge.” In all honesty, when it comes to a street car, I want nothing to do with all that.
Wheel sizing and style was also extremely important to me. I love old school wheels and the sizes they came in. I needed a brake caliper that would fit under my 15” Watanabe RS wheels without having to shave or drastically modify my setup. If it was not for being in love with these wheels, I would have opted for Z Car Garage’s larger big brake kit.
A few words about our latest big-brake kit solution. Our successful, larger ZCG BBK utilizes 328mm rotors and 4-piston calipers requiring a 16″ or 17″ wheel. This kit was made with our friends Tyler and Eric from Stoptech over ten years ago. Recently our customers asked us to make a BBK for smaller wheels so even a guy running 14″ vintage 5-slots slots could brake like a modern sports car. Typical big-brake kits use a 4-piston setup up front and a ZX in back; Proportioning is hard to get right, varying from car to car. We wanted a brake system that suited the car and totally bolted in, no M/C change, no proportioning valve, no booster change.
Working with Stoptech again, we developed this smaller BBK as a direct bolt-in solution for the 1970 to 1978 S30 Z cars. We’ve been with Stoptech since the beginning and love their products. We aim to release this product to the masses once our local installs are completed. Let’s get back to Glenn and hear his initial impressions of the big-brake kit:
Rob informed me he was working up a solution and he wanted me to be test the brake kit. Rob promised three things – they would brake amazing, they would fit under my 15” Watanabes, and they would feel as if they belonged on the car. Did I doubt it at first? Sure, a little. However, I also knew that the fit and finish of all products that came out of ZCG were top notch, and that Rob thoroughly tested all his products against his own standards. Which I’m sure everyone knows, are extremely high.
In preparation for the Monterey Historics last year, I had brought the Z race car to the shop for dyno time. Rob gave me the keys to his Butters Z and said “Go drive it.” Under 14″ wheels sat his brand new ZCG brake kit. I gladly accepted and took the car for a ride.
WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car, and these were on a car with stock suspension, tires and probably cruddy tires! I told Rob, “sign me up!”
Glenn wanted to run the brake kit on his Fairlady and we happily obliged. He had also been gearing up for a road rallye so the braking system would be throughly used. You can see his Z (top left) along with his buddy Erich C’s S30 (top right, also getting a ZCG BBK!):
Then came the day Rob called me up and said they were ready to rock and roll. Lucky for me, I was just about to head out on the 1000-mile Coastal Range Rally! The kit came with beautifully anodized front and rear calipers, hats, rotors, brakes lines, reversible brackets (for early and later Z offsets), and a factory ⅞” master cylinder. Read that again… Yes, a proportioning valve was left out from that list! The brakes were a straight bolt on and ZCG did all the math to get both the master cylinder size and piston sizes correct. We brought the car in for install and within a day the car was ready to rock.
Glenn’s 240z now had 4-wheel disc brakes ready to tackle the street and rallye:
And of course, the brakes fit beautifully under the 15″ Watts. Kane approved, and Glenn was stoked:
I could hardly wait to jump in the seat of the car and take it for a spin. The brakes were now on a car with suspension, tire, power, and a proper alignment. It was everything I had remembered from driving the Butters Z and MORE. The brakes performed flawlessly on the Coastal Range Rally, taking abuse from California’s most challenging roads:
Attention to detail goes a long way. This is exactly what these brakes delivered, and what continues to be delivered by ZCG.
LONG LIVE THE Z!
We are happy to report that Glenn is still braking late and still braking deep all while Enjoy The Ride! You can find him carving through the Santa Cruz Mountains:
Big thanks to Glenn for letting us work on your Fairlady! We also thank Eric and Tyler from Stoptech for supporting us and our precious Z cars!
