So many people are telling me they dont want the brake kit on the sl knuckles and they want a version for vr4 knuckles, i understand the wheel hub is easier to replace on the vr4, but the ears are much larger and its just not possible with these calipers.... because the wheel hub bolts on. I thought, maybe that could be used to tie into for an adapter, cut one ear off, and use the other. What do you all think? Is this jank? It would require two longer hub bolts, but i cant see any reason immediately why this wouldent work.... youd just have to cut your knuckles unfortunately.

This also gives the option to mount a lower or higher caliper, so whichever one you think is cooler (not center tho)

Lmk what you all think, thanks again :)

*The example images i made are in the higher position, it should be easy to imagine what a lower position would look like*

I am getting very close the the point where I will start ordering CNC parts and testing them on the car. before I do that, I need to get some information from anyone who would be interested in a kit like this:

1. how much would you realistically want to spend? I know cars are expensive to work on, and my goal with this was to make an affordable kit, But I also need to make sure im making a kit that is sensible for the people who want it, im not gonna cut 50 dollars on a feature everyone would be willing to pay for; regardless, i am rather confident I can make this kit cost less than other big brake kits, ESPECIALY compared with ones that are equivalently sized, etc.

2. how important is it for there to be an option for this to fit oem wheels (with a smaller rotor; this one is 15in)?

3. If I sold this as a kit, how much would you want it to come with. do you want to source your own calipers and rotors and only receive the bracket, mounting hardware, centering ring, etc. the reason I ask this is because there are many different caliper and rotor options. you can buy rebuilt calipers for like 150, and new ones anywhere from 350 to 500. you can buy decent normal rotors for 50 dollars each, or Brembo ones for 130, or fully floating for about 500. do you want it to include brake proportioning valves? brake lines? brake pads????

4. do you want this to be fully open so anyone can see all of the files, cnc their own bracket, etc? originally that was the plan, so anyone who needs to save money can. Then, id also offer it as a kit for anyone who wants to support me or just doesn't wanna source everything individually, but someone mentioned to me that it would be pretty easy for another company or person to just start selling them, which isnt be the intention of opening this project up. Ive spent a lot of money and especially time on this; it would be very frustrating if someone just made a copy and started selling it.

5. is anyone interested in testing? I cant promise this means a working kit right away; however, if the bracket changes, most of the parts should still transfer over to the final version. I have already tried the adapter on two different knuckles and the casting varies enough to where it doesn't fit on one but it does on the other. its an easy fix, just give more clearance over the casting, but these are only things I can know with testing.

general info for anyone who hasn't seen my posts before and wants details - this is a 15in brake kit using CTSV 6 piston calipers, and 2014 mustang gt500 rotors. because the kit is so large, you must use FWD knuckles with the kit. If you have an AWD car, it is possible to swap FWD knuckles on, and this would be a good time to do wheel bearings and CV axels too. you will also need aftermarket wheels, to my knowledge no stock wheels will fit this kit; some flow formed/forged 18in wheels will fit, most 19in wheels will probably fit. (the kit requires an INNER wheel barrel >=17in)

Ive made the kit in a way that no modification will be required; however, casting marks may need to be removed, I know for sure there is a letter mark on the 1991 and 1992 SL knuckle, but it is very very easy to remove. I filed it down, with the knuckle still on the car in less than five minutes with an old hand file from Walmart

Im sorry this is so long. Given its nature, I wanted to make sure anyone reading wouldn't have to go through all of my old posts to understand what is going on and I also need this information before I make some fundamental design decisions.

if you want more details or have questions don't hesitate to DM me.

I ended up getting a blue laser scanner, and I'm glad I did; there are many things I've been able to align perfectly in CAD that would have just been beyond impractical without it. ill probably test print the new bracket tomorrow.

assuming this design works out, the swept diameter of the calipers will be 427.3mm (16.8in). you need about 2mm of clearance, so you need your wheels to have an INSIDE barrel of at least 431.3mm (17in).
