: need some disc brake help

Ok guys I hate to ask because I know that these topics are repeated over and over, I tried searching and while I learned a lot of things I'm not sure that I found exactly what I'm looking for.

The car is a 64 2 door wagon, I've got a stock 69-up front disc conversion and am adding a rear disc conversion (11 rotors and parking brake calipers)

I'm also adding 18 inch eagle alloys 212 rims with BFGoodrich GForce radial tires.

Now here's my question, Since I'm upgrading to large rims I have a lot of room to upgrade the 11 inch fronts, what kind of upgrades are available using stock disc spindles?
I've read a lot about b body spindle upgrades but I'd like to know if there is a bracket available to add 12 or preferably 13 inch rotors on my 11 inch a body spindles. By the way I truthfully don't have money for a Baer or similar conversion, Thanks guys!

There is an extension bracket you can buy to upgrade to bigger rotors, which bolts to your stock spindles. I thought I saw one on ebay for $65 or so but I cant find it.

OR if you wanted to go all out you could get the C5 conversion and get some big fat corvette brakes up there....

Thanks for the reply! I've done some reading on the c5 conversion and it seems that everyone is doing this conversion on tall spindles which I really don't understand. In using tall spindles it requires that the caliper brackets be cut off the spindle and the backing plate holes be opened up to fit the bracket. It seems to me that the swap would be easier on A-body spindles since all you would have to do is build a bracket that mounts to the factory bracket holes. I can't seem to find anyone who offers this bracket for a body spindles.
Also in the conversion you have to create a hub, with the b-body rotors people are machining off the outer rotor and using the center as a hub, but with a-body rotors we have the original style two peice rotors, wouldn't they be easier to take apart and use the hub to carry the c5 rotor. I know I have a couple of sets of original rotors that are pretty much trash as rotors due to thickness.

Am I correct in any of this? If anyone has info it would be much appreciated, a template for the bracket would be great if anyone has done this.
Thanks!

www.Speedtech-performance.com is the only place I have seen that has conversion brackets for stock spindles.

Thanks for the link! Interesting thing is their bracket uses c5 calipers with c4 rotors so you're only getting a 12 inch rotor instead of the c5 13 inch unit.

You can get them with the C5 rotors but the C4 rotors are the heavy duty 13" the only difference is teh rotor thickness, the C4 roter allows for more wheel choices
