Yep, another new thread by me.

Just when I thought I could possibly lower the car to the ground and check out the new ride height in the rear, I noticed something... I'm missing some goddamn parts! I need the little screws that hold the discs to the axle. I tried to take the screws off my old drum rear end because they look like they are the same, but they are frozen on. I only have one, I need three more. Anybody know where I can get some?

Damn, threadmaster.

I don't recall what they look like, but the hardware store is always worth a try.

Is it possible those little screws were just for production...to keep the rotors hangin on the car while it was being built?
Kinda like the retainer/washer that went over the wheel stud to hold drums on other cars.

They aren't necessary. They just hold the rotor in place while you mount the tire to it

As you'll notice, the rotors themselves aren't threaded. The hub behind them is.

So when you bolt the wheels down tight, it sandwiches the rotor between the wheel and the hub. The rotor isn't going *anywhere* once you get the wheel bolted in place.

Eric's car had the same problem. The only thing not having those screws will do is make it tricky to keep the rotor from moving off-centre while you put the wheel on. But in the case of Eric's car, the rotors needed a rubber mallet to mount onto the hub, so they weren't going anywhere.

They arent necessary but i would say you might want to keep them on to keep the centered. But ive had three sets on my crx that didnt come with the holes and one set that did. So i guess it doesnt matter. I just went to the hardware store (cdn tire) and looked through the bolt bins till i found a flathead screw that matched the threads. Your lookin at spending about 50 cents for a little less trouble.

^^ Yep, they aren't needed. You're lug bolts will hold the rotor in. Only thing I would try if you REALLY want them is to heat em up, and get an impact screwdriver set. That'll either get em out, or break them. You really don't need them though. The disc is self-centering, and like vipernicus said, the rotor will be sandwiched between the wheel and the axle hub.

I used some bolts that I had lying 'round the shop, but yeah they aren't necessary.

I found one more, so I put one on each and mounted the wheels. I'm good to go!

Now you'll have a minor imbalance. You'd be better off with both screws on one side and two bolts or nothing on the other. That's how my bro's RX-4 was.

If it's anything like the older Mazdas, a couple short 12mm headed bolts like to type found on the tops of the rotor housings holding the rat's nest on, should fit fine. If they turn out to be too long, the bolts holding the exhuast manifold heat shield to the intake manifold will work. If you can't find any bolts of that size and length kicking around, some short 8mm x 1.25 bolts from a hardware store should do it. Match the threaded length to the stock screws.

The next common size down is 6mm x 1.00, but I can't recall which size Mazda used on the 1st gens, so which ever.

I just saw this in one of your many other threads.



It looks to me like 8mm x 1.25; same as the RX-4. You can have two bolts on one side and two screws on the other.

Cool, thanks Jeff.
