All this talk of 4-piston, 6-piston, 8-piston calipers
i mean how much distance r u really saving if u go from 4 to 6 or 6 to 8???? it's gotta b like a few feet, right???? i mean i can't see how 6 or 8-piston calipers have such an advantage over a 4-piston caliper...maybe im just being naive
could it b that the caliper is so big that 4-pistons just won't cut it, and 6 will give similar performance to a smaller sized caliper with 4-pistons???

I have 4-piston front and 2-piston rear brembos and it's absolutely scary how fast I can stop.
I'm not a brake expert by any stretch, but more pistons seem to make a difference.
Granted, having 13" rotors and brake pads to cover that area in the front helps too...

It really just has more to do with the contact surface area of the actual break pad. The pistons just ensures better contact (less flex) during hard breaking between the pads and the rotor.

If you have enough braking power to activate the ABS on your car you will not decrease stopping distance by adding bigger brakes. (at least not from lower speeds 60-70 MPH) The bigger brakes though will be able to resist fade much better and will not decrease in performace after repeated stops or a very long stop at high speed. Tires actually play a big roll in stopping distances.

After getting my wilwoods, I just feel like I have more control of the car when braking. It definitely stops faster w/o having to really slam on them like when I had my stocks, no fade, and turning & performance is improved b/c of the weight reduction (5lb caliper + 10lb rotor vs. 15lb caliper + 19lb rotor).

If you want to increase you brake power and reduce the stopping distance, you have to increase the rotor size!!! The number of pistons in the caliper do not assure you the lower stopping distance. It is the whole brake system design and the package 8 pistons are not necessarily better than 6 and 6 is not better than 4, etc. Take a look at the C5 Corvette, it has one of the best brakes in the business, including some very exotic sports cars. C5 doe not have 8 or 6 pistons in the caliper. The number of pistons is a marketing gimmick to sell the brakes

According to the June 2003 Car and Driver article on the Comptech Supercharged Acura CL-S, that car was equipped with the 13" Brembos. It also had 245/35/19 tires and the Comptech suspension.
With all of that Car and Driver states "The oversize brakes and tires knocked just five feet off the stock CL's 181-foot 70-to-0 mph stopping distance, but their real talent is fade resistance".
So I guess if your goal is improved stopping distance, it may not be worth the investment. But if you want looks or are racing and need the fade resistance, it may be a good option.

If your brakes are strong enough to lock your tires or kick off ABS, more pistons aren't going to help much. They will help with equally distributing the pressure and helping with the brake feel.
If you really want to improve your stopping distances, sticker tires are a much better option

My buddy has stock 4-piston calipers on his Supra TT (2-piston in the rear, I believe), and those f*ckers grab like a bastard. Now, he has slotted and drilled rotors. Haven't ridden with him yet, to see if there's any improvement.
I wish Acura gave us better brakes.

again.... pads>pots
like cusdaddy said, tires are important as well but get a high performance brake pad and you'll notice the difference much more than anything else
