Response Type BIG BRAKE kit, 13 inches for non-turbo hubs :)

Re: Who's interested in 2-piece brakes?

I am interested in seeing a final price. These calipers would be new or used?

Re: Who's interested in 2-piece brakes?

I'm running those on my 87' 2s with turbo hubs, only needed to move the caliper out 4mm to center everything properly, it's in my build thread of sorts… fit's nice, and at 11.8" probably all I'll ever need on that car, and I liked the logo (dba has 2-piece gt-r rotors for those at the bargain price of 800/pair)

My main concern with those calipers is they are very hard to come by in quantity and even more so regionally in small numbers --- the last thing I want is people crying about kits they can't source the rest of…

For me they aren't too hard to source for $400 just for calipers being in canada (mine ended up costing $370 rebuilt, with pads and rotors), but I think that's too high first of all, and it's not like I can just order a pair when I need them, I have to wait for availability, which is not a good thing if I plan to produce a bunch of kits (with or without calipers included)

So like I said, I'd rather standardize on something I can source new/rebuilt, and preferrably one that's not difficult to find through junkyards/ebay (kind of a junkyard too? haha), something used on many performance vehicles ideally, lastly something that comes in aluminum

Re: Who's interested in 2-piece brakes?

Im just going to throw this out there....

With s13 having infinite available bolt on methods for bbk like EVO and STI Brembos, z32, R32 just to name a few I think the main issue is the availability that these kits only work on the later style turbo slip on hubs. If you were able to provide 2pc rotors that were available to work on any z31 5 lug hub would be widely beneficial. Lets say used slip on hubs typically run $100, or someone needs to machine down bolt on hub for $100 either way your spending money to convert to a slip on hub. If there were rotors available for a simple z32tt 30mm brake swap (widely available) on any 5 lug car would be widely beneficial and easy to market. You could even offer a spacer kit that would allow for the z32 caliper -->350z track rotor (12.75" 2 pc rotor) maximizing the weight saving from not having giant hat and wasted rotor weight.

While big, there is a lot of added weight, and useless rotor on my 86 setup



I like your original idea, but just trying to help you with availability and mass market opportunities.

Re: Who's interested in 2-piece brakes?

UPDATE: Caliper availability is solved, I just need to plonk down enough money…

I will still need to get brackets made as they are radial mount, and will have to spec out the hat dimensions, otherwise everything is on target

Re: Who's interested in 2-piece brakes?

The calipers are radial mount? Like my motorcycle?
Jk

Re: Who's interested in 2-piece brakes?

What are you on about, I have 8 piston calipers on my unicycle!

Re: Who's interested in 2-piece brakes?

Radial mount calipers have been in use for a while in the moto side of things very cool tech just slap a wider rotor on and space the caliper accordingly.

Re: Who's interested in 2-piece brakes?

Yea it makes it easier to get a "stage 2" out of it with hardly any cost

Re: Who's interested in 2-piece brakes? update #1

Small update: I should have engineering samples of rotors in about 2 weeks, should find out then how well I've done my homework

Rotors = 330mm slotted high-tensile iron, just shy of HT350 for you engineer types
Hats = T6061 with 66m bore, dual drilled 4/5 lug

Calipers = 4 piston: 44mm x 2, 40mm x 2

Brackets = one thing at a time

Beefy brake pads teaser…

^ For Sumitomo calipers?

This is really funny.
