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

Hopefully I'll have updates and fitment for these over the next few weeks. Need to set some time aside to go over and mount them up on the car.

2 rotors .. 13"? Brand? Weight?
2 calipers .. Brand?
2 caliper hardware kits .. as in brake lines?
2 sets of pads .. Brand?
2 brackets .. These are the caliper relocation brackets?
4 bolts .. for the "bolt-on" rotors?

…optionally studs .. optional because "not" needed (asthetic benefit)? Brand?


I believe I read that someone else would be "selling" the kit. Is there an estimated cost? Larger rotors (custom), larger calipers, caliper hardware, brake pads, brackets, rotor bolts …

Quiz, it's pretty obvious that you are trying to push the brake rotor kit that you've had a hand in producing with these questions that have already been answered.
What are you trying to do here?

The calipers are G-E's own brand.
The hardware is used to install the brake pads. You don't get hardware with any of the larger brake pad sets.
The brake pads are shown on page 4 of this thread, and you can buy replacements in whatever flavour you like.
The brackets are to mount the calipers.
The bolts are to mount the calipers to the brackets.
The studs are optional to save on shipping because he's offering extended wheel lug studs for people who want to run spacers to clear their brakes with shallow wheels.
Why does brand even matter for wheel studs?

I'll just leave this here:

Actually, I just asking the same questions that were/are asked of the kit I have. With the penchant of z31 owners asking questions (why can't I?) .. Without reading the entire thread? The question should be? Why do you have such an attitude over what I post? I've never posted anything negative about G-ES's BBK. Why do feel the need to accuse or attack or even defend his BBK? It doesn't need to be defended.

Thanks .. Pictures answer most inquiries!

You're asking questions like what "brand" a damn wheel stud is- as if it matters. I am not defending G-E's kit. I am questioning why someone who has a hand in the development of another kit is the only one asking such questions with no obvious intention of buying.

My attitude is nothing personal. I just don't believe in seniority in a car club. :-)

The brake pads that come with the kit are super meaty too.

Also, no offense to quiz, but this BBK has in mind someone willing to spend the cash for a "serious" kit. Quiz's is nice for the rotor upgrades, but as he said "will only perform for 80 % of community" (basic daily driving/moderate track use). This kit has track use all over it and also those looking to have some amazing stopping power for the streets if needed.

Seniority? When have I ever .. EVER pulled seniority here ?
As for asking about brands .. It's no different regarding your questions about obtaining replacement parts when needed. You even asked if parts were commercially available or having only 1-source. Obviously G-ES's kit is made for the upper 15-20% performance minded who intends to push the limits (I like that) .. Maybe I'm wrong (I'm no expert, never said or implied I was) but I'm thinking someone who intends to track or race .. Might be interested in a good source of replacement rotors, etc ..

As for my wheel stud inquiry. I guess you're saying (I'm not) .. You can go to eBay and buy just any wheel stud to meet this application?

Yes, I do realize I could have read through all 4 pages and gotten my answers, but then you'd miss the opportunity to contribute …

And as for buying? Me personally ? Nope, you're right. But I do get inquiries from z31 types who don't visit the forums .. Asking about performance enhancements. I don't direct them to the forum, but to the developer .. The more I know (or don't know) helps put the buyer in touch with the correct developer/seller.

Cialis or Viagra works great. Back on topic.

I'm not saying that you did. But it does exist, whether you acknowledge it or not.
no hard feelings. it's just that some people don't say things to certain people. I say whatever. like I said. nothing personal.


300zxturboftw is right. Back on topic.

how does the quality of the kit look, 300?

It's really well done. Everything seems pretty solid. Just have to test mount it on the car and then follow through on purchasing the wheels I want to run for a few months. Slap the expensive tires on and I'm good for the summer after an alignment.

Holy crap children!

INQ: I understand your question about where they are coming from, you asked the odd question of brand, these are not off-the-shelf parts, everything is either entirely custom or a modified design, the brand is _mine_

I think the failure lies in assumptions, you came to this thread assuming that like many small-biz products, my kit would be a collection of things I've found with adapters to work in our case, the kit isn't an adaptation to the z31, it's designed from scratch for the z31.... partly why it took so long

More generally: The pads included are street pads, why not race pads you ask? Well everyone has different needs, street pads will let you get started without additional purchasesl; it allows you to feel the car, upgrade as necessary to the compound you find most appropriate… I'm not about to dictate selection, that will be up to the vendor or the buyer's shopping/researching efforts, it only makes sense to offer low cost pads

Studs: Since this was designed around non-turbo hubs which have tiny studs, you have two choices, getting normal length replacements, or again _my_ branded extended studs, I'm sure my price is competitive with any you will find, the question becomes why not?

There were some key considerations in this kit: The calipers are huge compared to z32 calipers, if the installation brackets placed the caliper in the same position, you'd need a 20mm spacer to clear any wheels that barely cleared the z32's… everything was designed around the premise that that would be bad (the rotor hat will already add offset), the caliper clearance is modest now, I think adoption would be slower if everyone had to buy wheels specifically designed around big brakes, which would also be bad

Whats the difference between the non turbo 84-86 hubs, non turbo 87-89 hubs, turbo 84-86 hubs? I think this may be important to address.
