price for salvaged 300zx rear calipers and disk.

[TatII]

thats goin to be my next upgrade since one of my rear calipers froze. i might as well replace them with beefy 4 pistons ones. how much do you think they go for in a salvage yard

Umm Tat,

You are going to have a problem since the rear Z32 brakes are not 4 piston but 2 piston or 1 piston...not sure since I havent had to check in the few months I've had my car but I am 110% dead on sure they are not 4 piston. The front brakes are 4 piston.

Rotor size is 11 inches in front; 11.7 inches in back (weird I know)

Skyline GT-R are 4 piston w/11.6 inch in front.

Another option for the front is the Q45 brakes that are 2 piston sliding but they have 11 inch rotors and same thickness of rotors as the Z32 brakes...and remember it had to stop a 4000 lb car...it does wonders for your car if you use these...

Here's a friend of mine's site...and does a Q45 install and explains some brake options under his Performance Tips listing.

Its funny I'm in the process of doing a 300z brake conversion. If you convert the rears you need to also get the entire parking brake assembly. The 300's p-brake is a drum unit whereas the 240 (my s-14) has a self-adjusting mechanism in the caliper body and a manually controlled plunger for the p-brake. The best brakes to get are the 91 na brakes as they are a bit lighter (aluminum calipers, slightly smallerand lighter rotors). The size difference is basically unimportant as either set turbo vs. na will be more than enough to lock up all four with ease. In the change over you will need special brake lines. I suggest going with Goodridge lines as they will have all of the fittings to fit in the retainers on the strutbody . Also I've never had a leak with goodridge line in any of the hundreds of lines of theirs that I've used. Oh yeah, the fronts are 4 piston the rears are 2 piston. Remanufactured parts can be bought from the parts store quite cheaply but buy cross drilled rotors from somewhere else oddly enough theyre cheaper than buying the stockers. About a grand to 1200 for the whole swap. Hope this helps.

damn that cost more then i thought, well sincei'mnot doin any real power mod on my car, i guess i'lljust replace it with a stock caliper.

Umm 1200 for the swap? Well if you want to spend the cash...you can pick them up for 950 from www.pdm-racing.com (but they are on back order)

But that's not the point...if you search for calipers under www.car-part.com you can find some junkyard calipers for alot cheaper...then get yourself some Powerslot rotors and some stainless steel Goodridge brake lines. Or search on www.twinturbo.net under classifieds. You dont have to pay over 1000 for this upgrade...

But in all honesty...you might want to get the TT calipers b/c the rotor width is 30mm vs. the NA caliper width which is 26mm and the TT calipers after 91 are IRON vs. the NA's which is ALUMINUM...now why would you say would you want IRON (weighes 10 lbs) vs ALUMINUM (weighes 6.5 lbs)...b/c in aluminum calipers...they dissipate the heat so well that it just transfers it onto the rotor...now if you dont have cross drilled or slotted rotors...then you are gonna get some crazy heat on the track on your car. But if they are...then you should be fine. The difference is small in the performance...but just get the TT ones since they are out there too and if you are going to spend the money just do it right...and not almost right.

PS: TatII what's your email address...I've tried to email/PM you but you wont respond.

Maybe I wasn't clear enough in my first post. But there was certainly a misundrstanding.
1200 is for 4 calipers 4 cross drilled rotors 4 brake lnes and all ancillary equipment. The pdm system for 950 is for fronts only. I'm talking fronts and rears. With '91 NA 300z equipment.
Here's why...

A stock 240 has more brake than tire. If running a stock car on tne street there is no real performance gain in going with bigger brakes. The problem with the 240 system is that after heavy usage (i.e. racing duty) the brakes tend to fade and become overwhlemed. If you were to use the car for autocrossing on the weekend and drive on the street during the week then by all means get the 300 brakes. Furthermore the reason I suggested the '91 NA brakes is that they come with aluminum calipers and rotors that are 3 pounds lighter each (fronts anyhow). We're talking unsprung weight also.
See the whole reason that Nissan went to the thicker rotor and iron calipers on the turbo cars is that with the extra power guys at the track were entering corners at higher speeds (boy thats a tough one to figure out) during on track sessions the brake heat would warp the 3mil thinner rotors and the aluminum calipers would tend to flex. So a heavier brake was needed. but we're talking about a car that weighs some 4-6 hundred pounds more than a 240.
Also a word on slotted rotors. The reason some manufacturers began slotting rotors is to evacuate the gasses produced by a brake pad during braking. This is only a noticeable problem when you are limit braking for an extended periond of time. Problem is that this also increses pad wear. Cross-drilled rotors will achieve the same thing plus they have better cooling properties. But you need to get them from a reputable company such as Brembo. Some companies drill the holes too large and or don't use good tooling which superheats the metal around the drilled hole making it brittle and thus, a lot of time, leading to cracks or worse chipping (slotted rotors will do this as well). Oddly enough I found that drilled rotors are comparably price with stock replacements. So to make a short story long are 300z brkes on a 240 needed? No. Do they look cool and give you bragging rights with you friends? A resounding, HELL YES!!
