LS1 mounting brackets

[brickyard69]

Does anyone know where to get the claiper mounting brackets that do not require the maching/grinding of the spindle for it to sit flat?

I think Speetech sells them. The is C4/C5 bracket the same (non-Zo6)?

My other choice is to just buy the typical flat 1/4 steel bracket and modify the spindle Has anyone done the modification 3/32? Is it simple?

Also, has anyone ground their hubs ro 6" themselves or is everyone sending it out to a lathe. I don't have a lathe and don't know where to have it done.

i am using steel plates on a 1st gen fbody & have not machined my spindles yet, but by my measurements show very minimal material will have to be removed from the bottom hole and about an .080" spacer will have to be used on the top. Yes I have to use a spacer on drum spindle unlike others that seem to say they had to machine the top mount. This just points there is a lot of variation in these spindles.

I spent about 2 hours turning my hubs on a lathe, but it had been about 7 years since i had run a lathe. The hardest part was chucking the hubs straight. Machining the OD of the outer ring (outside the studs) was not hard b/c you can set the rotor surface against the chuck. The hard part was the OD of the inner ring (slides through the center of the rotor). In my case this also had to be turned down and there is no great surface to hold.

Try a brake shop.

I leave the hub on the spindle, and put the spindle in the vice. Then I grind the outside of the hub while positioning the grinder to slowly turn the hub, thus turning the hub down in a uniform manner. I just use an angle grinder. Works just as well as a lathe IMO.

Thats what I did. I used a grinder.

i used a brake lathe with the cutting arm flipped over. worked like a champ. bout an hour and both fit inside the c4 rotor. i over cut just a little to compensate for powdercoating. i also used delco durastop rotors to get affordable crossdrilled rotors. all my stuff came from speed tech. larry's a great guy to deal with.

If you have access to a lathe, it makes for a much nicer job. I know some people don't have that luxury. A lathe will make for a much closer tolerance for your rotors over the hubs. As for the spindles, I used a small vertical mill and machined the top boss of the spindle .113-.118", I can't remember the exact number. I'm assuming you're converting from drums, right? Check your 3/32" dimension, it sounds a little short to me.

I had it done by a local machine shop.

He only charged me $25.00 to do both.

Did mine at work, and got paid to do it, sorry it's not nice put it's a perk,
