I did some work today and have finalized the kit.
We are able to use the current hub design with a few slight changes for the 84-85 spindles. However the GSL-SE requirement can not be met with this hub. Due to the fact that the wheel surface change of 15MM and the larger outer bearing, it has not worked out. I will continue to think about a GSL-SE solution.
The group buy has been setup -> https://www.rx7club.com/group-buy-center-69/1979-1985-12a-rx7-markii-big-brake-kit-677216/

It's too bad you couldn't get it to work for the gsl-se. Good to hear you will continue to think about the solution. Hopefully you get it all worked out. Maybe you might need to make a new hub? IF so, maybe you can design it to take the stock wheel bearings. Anyways, I will be patiently waiting on the sidelines
Thanks for all the work you do for us first gen guys!

So Billy...
these will fit Rx2's, without changing the pattern, only if I want it to be a 4x114.3 pattern, correct?
These look fully sick man, you are doing fantastic work...keep it up....just make those 1st gen. lowering kits for da front...:

So this kit isn't going to be offered with a slotted rotor? Also, I have one of the old rotary enginering cars. She started off as a 79, but I am not sure that it hasn't been changed to the newer style. I think it also has the strut towers raised. Is there anyway to check to know which I have? I am including a pic of the motor just incase anyone can help out. How do I order the optional calipers with it? And how can I convert to get the stainless steel lines on my 79?

What the lowering kit for the front you asked about?

No, the kit fits your 84-85 spindles. The kit is made for the 12A offset not the GSL-SE offset. it is 15MM shallower. You would need spacers or different wheels.
Yes completely different hub than the current design.
These would only work if you are using rx7 struts. They have both patterns in them, 4x110mm and 4 114.3mm. I am almost doe with the rx2/rx3 kits. I need a rx3 spindle/rotor and a rx2 rotor. Interested in letting us borough a rx2 front rotor?

No slotted rotor available. Calipers price is yet to be firmed up. Our line kit is for the fine thread mazda used. I will look into stocking the course to fine adapter. Get in on the GB and by the time we are ready to go, i will have the rest figured out.

Will you be offering the 15mm wheel spacers to use SE wheels? Would the studs need to be longer if using the spacer?

I could could do it if the wheel bore was larger. Since most would be using there current wheels, the bore would be stock.
So long story short........If your wheels happen to have a larger than stock center bore (Sometimes after market wheels are made large and a plastic spacer is used to bring the diameter down) you can find someone who makes 1/2" hub centric spacers that match your wheel and out hub. this would be close to the 15mm offset difference.

No. I spent a few hours trying to design a hub centric 15mm spacer that fit the current hub. Could not be done safely. Simply did not have enough meat while fitting on my current hub. I do not like non-hub centric spacers above 1/8" or maybe 1/4". Certainly not over 1/2".

Lowering kit was the one racing beat used to make for the 1st gens....raises the strut towers up 1.25 inches, lowering the same amount without the loss in travel.
Rx2 rotor, as in brake rotor? I've got one you can have...

Thanks Billy, I'll ask around and try and round up a few more guys for the gslse kit.

So many options!
Alright... So since my head is still spinning with everything going on, here's my question:
I've got a 12a '84 GS. I want to put these stock 2nd Gen rims on it:
https://www.rx7club.com/canadian-forum-42/over-6-months-making-663978/
(aparently stock vert rims)
What kit, spacers, wizardry, etc... would I need to take those rims and a big brake kit and toss it together on my '84? From what I understand the original kit gives '84s big brakes, but the offset doesn't allow for the use of 2nd Gen rims. Now there's this new kit which keeps the stock 12a S3 offset, but that still doesn't tell me if the rims will fit without spacers because they aren't stock 12a S3 rims, they're 2nd Gen vert rims...
Gah... why couldn't they just make an easier set of wheel offset and spacing standards?
While I really don't want to add more confusion, part of me thinks that it would be better if all big brake kits for the FBs were made specifically to match the 2nd Gen offset, because it's much easier to get their rims, and the aftermarket rims they use, than to try and match brake kits to the smorgasboard of rims we FB owners have been forced into using on our stock cars. If there were two kits (one pre-84 one 84-85) that simply said "bolt on, get 2nd Gen wheels, go" it might eliminate some confusion, though it would probably annoy the hell out of anyone who currently has 15" or larger rims on their FB.. and I can see that's not what you want to do!
