I am in the research phase of my 280z build and have been going back and forth between the Arizona Z Car Track Pack and Techno Toy Tunings Packages that match ACZs offerings. The overall plan is the build my suspension and brakes to be strong and able to do anything I throw at it, whether it’s auto cross, track days or daily driving. I will be going with a LY6/T56/R200 drivetrain. I know there are threads that talk about both techno toy and AZC but I haven’t seen any definitive pros or cons to either kit and I would love to know if anyone else has gone through this and where you landed.
Hey HybridZ crew! So I finally decided that after upgrading nearly every other component on the chassis of my Datsun, and a couple really lack luster performances, it was time to do the brakes! I was suitably frustrated with their lack of grab that I started to look into other options. Since this is primarily an auto-x car, I wasn't too concerned with heat dissipation and brake fade like on a serious wheel to wheel machine, and I was more concerned with keeping my weight down. Here's the car, zooming around at Nissanfest this year at Evergreen Speedway. With those factors in mine I went shopping and settled on the Silvermine Motors "Small" wilwood kit. It has the forged 4 piston Dynalite calipers up front and the billet 2 piston dynalite in the rear and traditional drilled and slotted rotors, rather than 2 piece rotors The kit also comes with all the lines needed to connect to the factory fittings. It even has the little retaining clips that always shoot off and get lost under work benches when you pull the stock lines! Edan at Silvermine was excellent to work with and guided me in the right direction on a couple things. Fastest shipping I've ever had on a part. Think he put them in the mail Thursday afternoon, and I had them in my hands on a Monday! Boxes contents all laid out! Well packaged, and everything in its place! Comes with some awesome 10.9 grade hardware, the only bolts you reuse are the front brake caliper bolts, which hold on the new brackets. Really well made and well thought out kit. The rear install is a breeze, once the drum backing plates are out of the way, and the ebrake cables are gone! Hey, its dead weight right? Since the Silvermine kit uses a 3 bolt rear bracket, I didn't need to pull the whole rear assembly apart, so I just turned the rear drum plates into pizzas! Just cut to the bolt holes and then flex them a few times, and they snap right out. The whole rear install probably took about 40 minutes start to finish. For my method, you don't need any really crazy tools or huge breaker bars, just a reasonable quality angle grinder! You could absolutely take the stub axles out (and it would be a perfect time to do rear wheel bearings) if you wanted to keep sparks to a minimum. Part of me wanted thought to see if it was possible without removing the axles, which makes this job MUCH less of an endeavor. The caliper mounts at the 10 o'clock position, keeping its minimal weight inside the axle line of the car. The front kit goes on super nicely. Remove and save the caliper bolts, and then remove the hub/rotor assembly. Why Datsun did it this way is a mystery to me, but oh well. I wire wheeled the mounting surface on the hub and the rotor, as well as chamfered the mounting edge of the bore on the rotor to ensure a solid mount. Bolt the hub back together and then put your new rotor on! Bleed and you're done! Overall impressions, these were really well made, I give them 2 wrenches out of 5 for installing. Depending on how you decide to remove your drum backing plates, it goes up to a 3 or 4 out of 5, particularly for a new to Datsun mechanic. I'm racing the car this weekend, so hopefully I'll have developed an opinion about the brakes this time next week!
