Yet another 6 bolt vs 2 bolt brake question

I took my 77/78 "Thick" brake rotors to a local shop to be turned. They checked them and said they are too far gone. I also have a complete 2 bolt brake setup. I priced rotors, calipers, and pads for both setups. The 2 bolt setup parts are $100-150 cheaper depending on vendor. My original intention was to run the 6 bolt setup and sell the 2 bolt setup. Now I am considering selling the 6 bolt setup and just using the 2 bolt setup to save money.

Is there any reason to go with the 6 bolt over the 2 bolt other than the thickness of the rotor?

I am keeping the 6 bolt hubs but if I were to sell the rest of the 6 bolt setup, what would it be worth? The calipers are cores and the rotors may need replacement.

 

I've got a 2 bolt set up on mine that will lock the 33" swampers if you stomp it hard enough. They seem to have plenty of power. I guess on a long grade at high speeds that require alot of braking, the thicker rotors could provide better fade resistnace and are less likely to warp. That being said, for around town and trail driving, I don't think you'd notice much of a difference.

Perhaps I'm wrong and there are other advantages, but for most people the difference is minimal IMHO.

 

I prefer the thick rotor set up for the reasons Dante mentioned. However, having said that, you have the other setup that is presumably in good useable shape, parts are more readily available, and typically cheaper. I'd go with the thin rotor set up and use the extra money on other Jeep related projects/parts/tools.

 

I just priced the thick verses thin, rotors pads and calipers, on line at http://www.oreillyauto.com. with free shipping the difference was less than $30. I would go with the thick setup for that difference in price.
