I was under the impression an LS400 caliper is the same as a JZA80 caliper....so yes you could, but there would be no difference.
MK3 BBK Kit!!!

- Start date
They have the same mounting points but they are different calipers.
I'm wondering now if the brackets were made to specifically fit those huge rotors (most likely) or if you could swap in the stock ls400 rotors and caliper (that isn't machined down) and have it fit correctly.

The op mentioned the calipers are machined down to accept 13.5 rotors, so you would have to send in your TT calipers to get machined down for it to work. If that is even an option, which I doubt.
Sorry guys been out of town. First off I am really not interested in customizing these kits. They are what you see. Caliper color is workable. We have access to about every color. It would just be $50 extra if you do not want the Black or Red. As doing a one off or very small batch obviously costs us more.
I will sell a set of brackets and rings by themselves but they are useless without out the CNC calipers. The calipers have to actually be cut down to even fit tight enough to the stock hub to sit down tight on 13.5" rotors so small rotors will not work at all! There is a large interference between the stock calipers mounts on the MK3 hub and the large mounting ears on the LS calipers.
As for 2 piece rotor hat combinations. The whole point of this kit is economics. It is a kit that most street and mild track day users will never push to the limits. The 5lbs per wheel difference in rotor weight is simply 1lb of boost(if that probably more like a 1/2lb of boost) to compensate. On a street car the weight is nothing in the spectrum of things that affect you on the street daily. I will be coming out with more kits as time goes on but the price will directly reflect these changes. There are currently kits available on the market with 2 rotors and hats and a reasonable price. So the who goal with this project is to not compete with them directly but rather offer another option. And one at under $1000 which I have done by quite a bit.
People keep asking about deposits. I will start accepting deposits after 15 people have fully committed. If you have posted saying you are in but not fully committed please tell me so I can remove you from the list until you are fully committed. As I do not want to get 15 on the list and then find out only 5 are serious. So if you are serious and committed please go to the GB page and post your name in the list or make it clear you are fully committed.
Thanks,
Seth

Did the pad contact increase vertically with the different 13.5 rotors on this kit? Or no, and only more surface area is gained for the pads to ride on once brake is applied?
Also, does the pad contact the whole braking area on the rotor? No extra surface free riding and will start to rust right?
Lots of questions before I commit.

Not sure what your first question is asking? But at this point it is more like you are questioning the quality of the kit, go to my Misc vendor page and take a look at the products I make to see the quality of my products. I don't produce products just for fun. They are all performance based, so as a whole to answer you questions the pad covers the entire rotor mating surface although there is pad over hang to the outside which is common with almost all systems. If you are unsure then wait till after the group buy is over and see the reviews and go from there!
Seth
I am guessing it is going to be around $75 extra. I have not packaged one up to ship yet but just based UPS's shipping calculator that will be about right.
Thanks

What is the piston area, swept area and effective radius (torque radius)? Please compare to stock. Thanks.
sorry I didn't read the whole thread but is this possible to have blank rotors instead of drilled rotors? I already had problems with drilled rotors.
Also, what's about the brake pedal. I have a bbk and because the calipers (alumimium) are flexing a little bit, it make the brake pedal feel soft but it brakes very well. What's the feeling with this bbk?

What happens if not enough people sign up? You got me breathing all hot and heavy over this kit and then there was talk of you doing the rears YEAH BUDDY! LOL
If not enough sign up for that price I will make a proposal to the ones who have signed up at a slightly higher price as obviously that price break is determined by the number of initial customers.

Just looking at an outside point of view here and not meaning to sound like a dick here however people just wanted to know some basic technical data on the kit and then you appear to challenge them as if they are insulting your products? I would have to say thats not a very good buisness tactic.
If you would take the time to answer questions like these which should be pretty basic if not essential stuff you would likely sell more kits:

Again not trying to be a dick here, just pointing this out so people will get the information they want and therefore you will likely gain more sales.

Do these rotors have the same offset of the stock ones? As in does it move the caliper closer or futher away from the rim. I know you made that hub ring spacer, but dont know if you used that to locate the rotor to match the caliper or just how you made it.
The rotors are further in to give wheel clearance. This puts the caliper and rotor as far in as possible while still having proper clearance on the steering knuckle. But needless to say no the rotors as a whole do not have the same back spacing as stock.

i've got conflicting info reading through the thread but are the rotors off the shelf parts too? IE-once i've bought your kit and need to buy new rotors of my choice, can i go out and buy a set of centric blanks or whatever I want, or am i stuck buying new rotors from you?
also, what's the distance from the center of the hub to the highest part of the caliper? I need to measure against a few wheels i've got to confirm they won't clear my 17s. The LS400 has stock 12.4" rotors for the years that had these calipers, and they fit under 16" wheels. so even upping the rotor size an inch theoretically should let them squeeze under 17" wheels. LS calipers are thick as hell though, so you usually ended up needing spacers to clear them laterally.
How much of the bigger rotor is used? i saw in the pic you posted that there seemed to be an approx 3/4-1" circle around the hub that isn't in contact with the pad, (this pic: http://img.photobucket.com/albums/v414/sethron71/MK3 BBK/IMAG0375.jpg) Is that true or is it ust the light/angle of the shot?

Not sure where the information is conflicting. They are off the shelf rotors so you will be able to select what ever rotor you would like when you go to replace them! I will tell you now they will not fit under a 17" wheel. They only clear the inside of an 18" wheel by less than a half inch. The rotors are actually 13.1 inches. As for the picture the rotors are unused in the photo so there is no wear area on the rotor so it is just angle and lighting. There is only about a 1/4" of unused rotor which is typical. It puts the pads all the way out to the outer edge.

how do you round a 13.1" rotor to a 13.5" bbk!?sethron71;1789091 said:
interested in seeing a used rotor pic though.
