Frank’s 1975 Datsun 280Z features our Z Car Garage Big-Brakes, Z Car Garage CV Axles, full suspension refresh, 240Z bumper conversion and Panasport wheels. Before we dive into the work let’s see how Frank and Patty found their Z car…
FRANK: Our 1975 280z was affectionately nicknamed “Charlie” in 1978 when we became the third owners of the car. I was 22 at the time and my parents had promised to help me buy my 1st car when I finish college. My girlfriend Patty accompanied me down to San Jose to look at the car and test drive but more accurately she had to do the test drive of the manual transmission because I only knew how to drive an automatic transmission. I think I made up the story that the 280z was for my “little sister!” From that moment on that Datsun Z became part of our lives. A short while later we drove “Charlie” on a nice day trip to Monterey where I proposed and I even wrote Patty a note promising that if I ever screw up our marriage, the Z is hers. Talk about a unique prenup!
Anyway “Charlie” has always been with us often as a daily driver to school, work or sometimes to Sears Point to watch that actor race for Bob Sharp. Servicing was usually done at Z Doctor in Richmond or Hayes Auto in the city but as the years went by and these places closed we started to rely on neighborhood service station mechanics.
Fast forward 37 years later, approaching retirement and a big move to San Diego one of my work colleagues who races Miatas asked me if I had ever heard of a fellow vintage racer Rob Fuller who does wonders on Z’s out of his shop Z Car Garage. After exchanging a few photos, Rob agreed to take on a new project. Luckiest day in “Charlie’s” life!
ROB: Frank was a doctor at a SF hospital and his colleague (Matt) was racing Spec Miata as a newbie while I was racing full-time SCCA in 2022, no longer taking any work in. So through a racing connection I was able to take in their car. We performed extensive work on Charlie: injectors, header, ZCG exhaust system, all hydraulics, clutch, Z Car Garage Big-Brakes, heater core, 240Z bumpers, full suspension and 16×7 Panasports.
Suspension
The suspension was refreshed with Techno Toy Tuning parts done in ZCG black finish. KYB strut inserts with Eibach lowering kit, T3 control arms, tension rods, urethane bump stops, rack bushings, control arm bushings, ball joints , f/r wheel bearings, ST sway bars, mustache bar bushings…everything was powdercoated or zinc plated.

Z Car Garage Big-Brakes
We are proud to have several of our ZCG products on Frank’s 280Z. We installed our Z Car Garage Big-Brakes (for small wheels) which have the been standard on numerous ZCG builds.
As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel and retaining factory emergency brake lever! A few details below:
Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)
Rotors: 280mm x 20.6 with Alum 7075 hats
Pads: Stoptech 309 sport street pads
Frank’s stock disc/drum brakes were removed and we installed our ZCG Big-Brake kit.
At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. New OEM Nissan master cylinder and Factory handbrake functionality IS retained!
Z Car Garage CV Axles
Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 250 CV axle kits on customer cars and we are stoked with all of the positive feedback. Frank’s ZCG CV Axles set #0047 shown below:
New motor mounts, tranny and diff mount. The differential was resealed:
Panasport Wheels
Complementing the new Big-Brakes on Frank’s Z are Panasport wheels! We installed 16×7 Panasports with 225/50/16 tires and performed an alignment:
Engine
We knew the car would be stopping and handling better than before, so next up was the engine bay. Once up and running we found the head gasket weeping. We replaced the head gasket, did the front timing chain set and refreshed the top end:
A Koyo race aluminum radiator with upper and lower hoses was installed to keep temperatures in check. The heater core was refurbished:
Beyond cooling and fuel system work, the engine was largely untouched to maintain factory reliability. The intake manifold and all associated plumbing was cleaned up and injectors replaced. We replaced intake and exhaust manifold gaskets with factory Nissan parts with a few ZCG tricks like our exhaust nut and exhaust studs.
New alternator before/after:
New evap canister:
The exhaust manifold was replaced with a 6-into-1 header and EGR kit leading to our ZCG exhaust system with stainless resonator and slash-cut tip.

S30 World Fuel Tank
We decided to start fresh with a new S30 World fuel tank. Great product from owners Gustav Oplasnik and Chris Visscher, Z enthusiasts/restorers. All the vapor hoses in the back were replaced and hatch weatherstripping to eliminate fuel smell in the cabin:
Interior
Recaro Specialist seats in leather are our favorite upgrade to the S30 interior:
Another upgrade to the interior of an S30 is our ZCG sound deadening package. The result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors. All weatherstripping was replaced on Frank’s 280Z:
240Z Bumpers
Frank wanted to clean up the exterior lines and replaced the large, factory 5-mph bumpers with chrome bumpers from a 240Z. We installed aftermarket F/R bumpers after our man William closed up all the holes and finished the paint work. Enjoy the before/after photos with more in the gallery below.

Enjoying The Ride
We shipped the Z back to Frank and Patty in their new home down in San Diego. They were super stoked with the ZCG work performed and immediately began driving the car. Their first car show was The Main Street America car show in July put on by the Corvette Club of San Diego. Over 400 cars with a Datsun category.
FRANK: Rob and ZCG basically made our 280Z the awesomest most fun to drive ever. The list of replacements and improvements is too long to list but basically incredible upgrades with ZCG BBK, suspension rebuild with KYB struts springs, new bushings, ball joints tie rods control rods sway bar etc… and ZCG 2.5 exhaust system, ZCG CV axles, all new hoses, Koyo Race radiator with belts and so much more! Cosmetically a new head turner with 240Z style bumpers, beautiful bigger wheels with sticky tires and Recaro seats that are the envy. Again so many upgrades a long list but needed and appreciated. “Charlie” is faster, handles better, brakes with authority and what a tone!
Patty and I will always be grateful to Rob for his expertise, Z enthusiasm, honesty and did I mention sweet singing voice. A true pleasure to work with.

Big-Brake Kits Available For DIY Install!
Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Christopher’s beautiful S30 and his ZCG Big-Brake installation:
Our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake function. Chris successfully installed the BBK on his Z and they look great behind the 16×8 (zero offset) Watanabe wheels with 225/45/16 Toyo tires. Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments.
CHRISTOPHER: The car feels planted like never before. Our family also has a fully restored 73 240 that is an excellent OEM example. Where that car feels stable and drives well, there’s no denying the age of its component and it drives like a seventies sports car. The 280 feels like a modern sports car and inspires confidence. The brake pedal communicates exceptionally well and the balance of the calipers bring the z down from speed a rate well beyond most cars today. The light weight of the S30 and the size of the ZCG big brakes is an unreal combo!
