    Builds New Here. Freshly aquired low mileage FZJ81 + Build thread

    Thanks! Honestly if it weren't for Quebec, I wouldn't be 2 years behind on this build. Really made it difficult for me to even want to do anything to the 80. Congrats on the low mileage JDM 80! I really do think they're much better buys than domestic market 80's in North America most of the...

    Oh, no I will never go manual brakes on an 80. I just don't see a reason for hydroboost if you can properly set up a modern braking system pretty much from scratch. It'll be better than tossing hydroboost on factory brakes designed 30 years ago. You're basically just adding more clamping force...

    Informative tech video on braking perfromance from Genright with guest R1 Concepts. Re-iterates most the things I've said in this thread. How important bias is, using prop valve, factory or aftermarket, or even hand picking piston sizes to fine tune bias. Personally think LSPV delete is more...

    Brakes, soft pedal, looking for more stopping power

    Looked at DBA pads briefly but couldn't find more detailed info about them. They only seem to state temperature ranges and nothing about friction levels. I needed rear pads that had high enough friction level to match the power up front. Personally been running Wilwood, EBC, Hawk, and...

    Speaker upgrade - looking for some advice

    I'm personally only ever doing front stage setups from here on out. It just means only having speakers forward of the listener. Just sounds better, it's how stereo recordings are done. Buy a pair of speakers you like, whether it's co-axial, 2-way, 3-way, with a headunit and if you're feeling...

    I may make very few exceptions ;) As mentioned in above post, I helped @BayArea80 with pros and cons to different options out there, and he still wants to run my rear with his FNSL + 14" tundra rotors.

    Kit will not leave anything on the table that's for sure! I'm comfortable claiming these will demolish anything out there because I've been running Wilwood's for 18 years, building and tweaking my own personal kits for almost 10 years, and thought about every possibility out there for the 80...

    Some data points for people: Here I have calculated brake torque front and rear based off of completely unmolested rear line pressure(no factory or aftermarket proportioning valve) and a .37 mu brakepad friction coefficient. Now here's with my current Stage 2-Lite setup using WW Aero caliper...

    Thermal capacity. Look at how small the pads are. Not just surface area but pad volume. There's no mass to them. Full line pressure at the rear(meaning fully open LSPV or Prop Valve), accounts for 42% braking forces on the 80. So up to almost half, but of course factory or aftermarket valve...

    @jcardona1 @Enders SOOOO big update from my contact at Porterfield... As mentioned in previous post the black rotor is a 14.25"x1.1" rotor from wilwood parts bin that has the same bolt pattern, same brake shoe ID, and almost same exact disc offset. Only issue that did NOT allow me to use it...

    Not a highjack at all! From first page I do have a cable actuated caliper on hand. ^^ This is just a mockup of a 14.25"x1.1" rotor from Wilwood parts bin. It has exact same inner shoe diameter of 9.04", nearly same disc offset as factory, and is 6x139.7 that I thought was compatible but sadly...

    Yes it will as the rear would just be a rotor and pad upgrade.

    Electronic will be button/switch operated. I don't expect to sell much if any of the rear kits. Mostly doing it for myself. I don't think the push button PB is what will scare people away. I can tell you right now it will be more than double the cost of the F+R Lite package. The cost is...
