Drum brake upgrade kit, interest?
Guys, we would be looking at 3 kits here if enough interest is shown:
79-83, drum to disk conversion
84-85, drum to disk conversion
84-85, drum to big brake conversion.
This will cover all the possibilities. Since the 5 lug axles can only be done for 84-85 housings we do not see doing the 79-83 to big brake.

Very interested.
The braking is the only thing I feel could be greatly improved.

I'm sure they could be fabricated. It's just stamped steel.

Is there still any interest in this. I have an 85 GS that i am rebuilding and I Would prefer to put the $ into disks right away rather than redoing the drums then converting. This would be so much easier than getting a GSL rear axle.

Sorry if this is a little off topic. I just found respeeds site and saw the 85 big bearing to FC conversion. Does anyone know where I would find out if these would be track legal? I am interested in tracking this car at autocross, or time attack. I am totally new to the race scene and just trying to make sure what I build can be raced. If anyone knows where I can get class Regs that would be great.

Billy, when you get this ready to go for the SA drums will you address these issues:
- E brake cabling conversion
- Hardline/softline routing and conversion
- Proportioning valve
as either part of the kit or directions for what parts can be used for solving these and advice for implementing solutions?
BTW, you do this and I'm in on it for my next upgrade.

So I went to MAZDA yesterday with my usual cache of parts requests, and one of them was rear drums for an 82 RX7.
His response?
NO MORE.
You have to go to NAPA/Autozone/etc to get them!

Bump!
Billy, I have an ignorant question to ask you:
Thinking about getting the SS brake lines you guys offer. Considering the car right now is rear drum, would the drum to disc conversion require me to get new rear lines or would I be able to keep my old line? I am 95% sure I will need new ones, but it never hurts to ask!

In the drum brake setup, you have a line going to the driver side and then from there that goes to the passenger side and you only have one bleeder on the passenger side. In order to bleed the calipers properly you'll need a bleeder on every caliper and would have to do something like what the cars that came equiped with disc brakes have. What they have is a machined Y block on the axle (I don't think the Drum axles came with this braket for it) but from that Y you have one line that goes to the passenger side, and another to the driver side.
