today a freind of mine at school told me he got some 300zx calipers front/back and i was wondering whats a good price that i should tell him cause he said to give him an offer and i dont really know how much they go for.(im trying to put them on my 02 5.5 gen)thanks

 

oh and i forgot another thing are the calipers on a n/a and a tt different or same

 

How to differentiate the different calipers.

Prices will vary according to condition.

that should do you good

 

i will call him tom and find out

 

ok i talked to him today he said he got it from a 91 300zx. another thing i was wondering is the clearence i sure i reead that my stock 02 gle wheels wont clear but would the 2007 350z rims clear the calipers? thanks for the help

 

91 should be aluminum 30mm calipers. not the best thing for a daily driver that sees stop and go driving all the time.

 

No one looky at my linky?

and why wouldn't that be the best thing for a daily driver?

 

the aluminum warps from the heat generated on braking.
that is why nissan went back to cast iron ones after 92.

 

I used mine for like 2 years of hard driving, autocrossing, etc with no warping problems. And I do 25 miles each way on the DC beltway, which is 80-5-80-5 mph over and over again.....

IIRC, Nissan went back to cast iron because nissan is CHEAP and iron ones cost less to make. The price of Aluminum spiked BIG TIME (more than doubled) in 1990-91 (before it dropped alot in 1993-94). Iron was running about $20 per 100 lbs, while aluminum was over $100 per 100 lbs at that time.

Warping might or might not have been an issue, but I'm betting cutting costs had more to do with it and Nissan just used that as an excuse so they didn't look cheap.

btw, to the OP - you can't use the rears since they don't have the ebrake assembly you need.

 

I thought the consensus was that the iron calipers flex less?

 

warping was / is a huge issue on them when they are beat on consistently (overheated) because of the 2 piece design. Aluminum warps faster than iron does. cost cutting probably did factor into it as well.

true too

 

The consensus by who? I'm not aware of anyone here who switched out their aluminum z32 calipers for the iron ones. And having spent a good deal of time on the z forums I never really notices alot of people complaining about the al caliper flex (maybe a couple people tops).

I don't know, I can't think of how someone can beat on brakes any harder that I do. Besides autocross and my commute, the z32 calipers did alot of mountain driving, usually with a full load of passengers, gera, and ski stuff...I neve had any problems.

Aluminum, theoretically, is more pliant than iron - but look at pretty much all race calipers, performance calipers, and BBKs - all are made of aluminum. Some flex more than others, there's no denying that.

I'll give you the fact that at the limit, the iron calipers are most certainly stiffer than the aluminum ones....But let's be honest - how many maxima.org'ers are overheating their brakes or braking at the limit? Not many....

 

so how much should i ask him to sell it to me for
