OK so I have these 993 rotors laying around and figure I can put them on my car and have some great brakes. I have a pair of 911 struts and hubs coming from the west coast but figured I would get a jump on this with the extra hubs I won on EBAY. That way if I mess up I can just get some carrera rotors and use regular good brakes. I have been looking at some of the 911 guys brake conversions on the bird board. The hubs need to fit down inside of these rotors but need to be modified so they will go in.

This is the lip that I must remove

I dont have a lathe here at the house and there is a new guy over in plant maint who is watching guys to see who is doing home projects So I figured out if I put them on the rear axel studs I could spin the axel and use a die grinder to remove the extra lip

Here is after a couple of minutes but my boy got tired of spinning the axel

I got it almost down in to the rotor but had to stop to watch the rose bowl. Will post more photos tomorow I plan to make my own adapters for the front calipers once the struts get here. Then the next chalenge will be the rear rotors and brakes.

just a thought.... how unbalanced is the hub now?

albeit its all close to the center (less effect....)

I will almsot guarentee these hubs are not balanced at the factory. The hubs on our riding mower look like more effort was put into making them These had flashing on them left over from when they were made

More work on making this work today I got it in and sitting flush

This is as close as the pre worked hub gets

this is a side by side comparison of the hubs

here is up close of the face end of the hub where the rotor goes up against. It is not as thin as it looks because you need to cut a 45 Deg. chamfer on the edge because down in the rotor it is not a square corner from the side to the face. I would guess they do that because of stress.

Ill start in on the other one tomorow. Does any one know the length of the caliper adaptor block for big reds? I have a chunk of 7075 T Cap about a foot and a half long where each leg is about 7/8 inch thick and 3 inches wide that I plan to use to make these

I turned mine on a lathe to fit 996TT rotors. Unfortunately for me, the 6-piston Brembos I used didn't lend themselves to machining adapters, so I had to fully commit by cutting and welding substantial mounting blocks.

You're on the right track.

another:

gawdamn.... 100mm studs?

Oh yeah!

The adapters you need are available from Steve Timmins in Delaware. He's the one who first started using the late style rotors on early hubs.

Thanks, Unfortunatly the new guy in the shop has cracked down on home projects. So I get to do this the go old fashond shadetree way and improvise. I only used up about 10 3 inch sanding discs.

i love the advertising

Again, not cheap and more than you need on a 2500 lb car.

thats cool!

joe....thats a PCCB caliper, right? are you using the composite pads?? because thats not the composite rotor...or did you just paint the big red brakes, yellow

It's a PCCB 6-piston caliper with Pagid pads for 996TT metal rotors. The caliper does have ceramic pistons, but the rest of my system is conventional.

Took my old brakes off the back today and started to figure out what all Ill needon that end since my front end is still in Cal. Im going to need the 100 mm studs like Joe has and a 2 inch spacer to make my wheels clear.

The old calipers are almost like new. The park brake still works smoothly on them. Im going to be putting all the old brake items in one package to sell. The rotors have some surface rust but I dont think have ever stopped a car. Remember this basic car has sat since 72.

Like new pads
