Yet another BBK idea...
I don't know if this has been brought up or not but here goes...
I've been trying to come up with a decent brake up grade that will fit under the factory 16" SE wheels. As far as I know, 300ZX calipers dont clear the wheels. So what about usinga twin piston sliding caliper from another Nissan? This would allow for a bit larger pad and more clamping force. It also might not throw off the brake bias as much when used with stock rear brakes.
I know the Xterra uses a twin piston caliper, as do some other japanese sedans.
Anyone got anything to add to this idea?

That might work. But you need to verify the dimensions/offset/mounting of the caliper vs oem. But from most reports of people using even the 4 piston caliper, didn't really report any better braking when they used the stock sized rotor. They DID however report much better fade resistance.
So depends on what you are looking for. More fade resistance? This might work. But if you want better braking dist control, IMHO you need to have bigger rotors. Don't know what rotor/caliper will fit under an oem 16" wheel.
In theory, using a twin/quad piston caliper should provide more clamping force thus better braking. But doesn't seem to be the case. Or if it is the case, the improved clamping force is not readily noticable.

the cefiros in taiwan have a upgraded OEM nissan two piston caliper that should mount the same and use the same size rotor.
might want to inquire daveb if any of those parts are possible to get here

correction, maybe not OEM.
but look here and down the page

I have heard that the 3-gens in UK used 2 piston calipers as stock equipment. But even if you could find a set (rare), shipping them over would be expensive.
I believe the Q might work. But I do know they are cast iron. I forget if they are 4 or 2 pots though.

From this page: http://importnut.net/300zxbrakeswap.htm
One good alternative to the 300zx brake swap is the hardware found on the Infinity Q45. The equipment will mount just as the 300zx's units, but will offer more wheel clearance. The Q45 front brakes are the same diameter as the 300ZX rotors but only come in a 28mm size. The main advantage to the Q45's equipment, is that it uses a 2 piston slider caliper. The pistons are located on the back side of the caliper allowing the front side to offer nearly the same wheel clearance as the 240's stock brakes.
For those interested in avoiding the purchase of new wheels or wheel spacers, the Q45 calipers are a noteworthy option to consider.

But, he wanted $500 for a pair of them, so no lower-cost 2-piecers I've come across as of yet.

Yup. That is what I gathered too. But they aren't really that clear unless you ask them point blank like you did. hehe. Since the hats are custom made, I don't see why oen couldn't order them to the Nissan hub bore and stud size. They must have that program/tools as they should have 2 piece rotors for Nissans. You can't just use a Nissan hat as the offset would be wrong.

Interesting....
I kind of like the LED mirrors and what looks like SplitFire ignition coils.

Ben, even if you have to go to 17s, this is still the best/cheapest alternative.

Anyway, new wheels are not an option.

the pads need to be shaved because on the Q pads where the wear sensor is installed rubs on the center of the rotor. no big deal, 2 minutes on a bench grinder and all is well.
theres not much else to know. braking power is much better but the pedal feel leaves much to be desired.

Every time someone put the 4 pots on the small rotors, most report more pedal travel. Which is logical. But most if not all who use the Cobra/2k4 rotors don't seem to report this. I would think with the Q calipers, it shouldn't affect the pedal travel nearly as much. (unless those two pistons are huge). I'm suprised that person experienced enough pedal travel to post about it. You guys should look into what the Q's MC size and shape is.
