Those might work. We'd need to get some measurements and contact Empi to see if their bracketry all lines up first. Then spline count and diameter in the drum would also need to be verified.
Finally if everything lines up, you'll have to drill and tap a new bolt pattern in the drum.
Honestly, the kit is a decent price. If you want we can tear into that rear suspension I pulled out of the red car to take measurements from.

How often and how hard do you need to break in that 924? Are you sure the brakes are in good working order right now?
I remember my 83 NA brakes as being absolutely superb.
An upgrade would be self adjusting drums from a late car and some performance shoes. Ask the others but maybe a late 924 or early 944 master cyl would also improve the feel of the early brakes.

For that money, you could source the used components you'd need for five lug conversion. Of course, you'd still want pads and rotors, but if you got lucky, the donor car might even have usable rotors.

I really don't think it is worth investing much money in, a self adjusting system would be great. I did an HPDE school in April and the brakes worked much better than I expected with no fade or problems. That was 8 25 minute sessions over two days. Even though I constantly worried about them they were fine. My only change was to use the Porterfield street grade shoes in the rear, which I'm not sure are worth the money, but probably better than the typical aftermarket shoes. They needed adjusting when done. I put several years of tire wear on that weekend and I'm sure the brakes took the same abuse.

Not surprisingly I have a full 5 lug set up for sale...

Haha, my first thought was of you Leigh.
I dunno, I think 4 lug with rear disks would be very unique and barring minor machine work would be simpler.

| If it was the same lug pattern as the 924 it would be more interesting. |

I guess. Seems like a lot of work though. For $100 less you could have original Porsche parts like vented fron rotors, heavier front 931 springs, Koni stuts etc.

Well if you'd already drill the holes for right pattern, is there anything that would stop you from drilling the same holes to 5-lug parts?  |

If one would insist staying 4lug (for example because of some really-really nice wheels or something), it would make sense to use Peugeot rear rotors+calipers. AndrewNZ did it, they work well.
Other than that, just go Porsche 5lug, easy and cheap too.

Can you lock up your tires at highway speed if you had to? |

Ive been tracking both sprint distances and endurance with 125hp and also 12h endurance racing. The drums do just fine with stock liners. I once tried racing liners when I tracked my n/a but it wasnt worth the hassle.
Biggest drawback for me is not braking performance but the constant adjustment you have to do if you track them (having proper play is important to not get dragging shoes when they get hot and expand), and the spongy feel that is hard to get away from.

The idea is NOT to lock up the wheels.

When you press the brake pedal all the way (hard-as if you were trying to lock them up) do you feel something bottoming out? Like in the booster or maybe the pedal touching the floor? |
