Are 2 piston rear calipers enough for a single seat (1800lbs) 12 car? Or are 4 pistons needed?

Thanks,
Grayson

I would price Pro-Am too. I have Pro-Am (Kartek) and I am happy with them, especially since I can drive up the road and they have everything in-stock

Does Pro-Am make a non-micro stub kit? I have not seen one.

CNC has a aluminum hub.....wouldn't this wear faster than the cast drums??

Jamar says it has a chromoly center....seems like this would be better.

Anybody have experience with these?

Can't afford Pro-Ams or CNC....

Trying to decide between Tatum and Jamar...

I have had good luck with the Tatum calipers so far. 5 years on my prerunner and a full season on my race car so far. I have run CNC with plenty of succes as well. Don't sweat the aluminum hubs as they all have the steel centers on them.

Just buy Wilwood calipers. Great price, great quality and available everywhere.

Do you use the Tatum hubs as well?

Thanks for the info.

Not that particular type but yes. I have their Midboard hubs on both my prerunner and race car. ZERO issues in about 9000 combined miles

Hey 'Stroker is this normal? The splines on the hub (and old drum) are longer than the splines on the stub axle. Probably no big deal, I just don't want the axle to dig into the hub like it did to the old drum.... BTW, they are T1/930 stubs.

Run your nut on by hand. If it looks like you will be able to get the cotter key in you are good to go. Other wise I would check your spacer arrangement. Looks like the hub will pull in a little furthur by torquing. One of the reasons I hate Type 1 stuff. Too much stuff to check/remember.
