I have already searched for this and researched

i just finished putting the SR in my 1990 240sx but the brakes on the car are beyond shady and it get scared sometimes. so i figured i would get the most bang for my buck with the 300zx brakes. but my question here is, people usally do a 5 lug conversion or just re drill the rotors for fit 4 lug.but can u just get rotors for another car that will work with the 300zx calipers and are already 4 lug for i dont have to drill or do 5 lug conversion. if there are some rotors that would fit please name them for me.

also has anyone every went to autozone or similar places and traded in your 240 calipers for rebuilt 300zx ones. and if so did u hafta trick them into this or did they just do it or did u work something out.

last question ... how much has each of u spent on diong your brakes and how much should i expect to pay

thanks alot guys!!

I've heard they never even notice when you trade your calipers in, just dont even mention it to them.

Here's a good thread on the 300ZX brake swap.

http://www.nissaninfiniticlub....35165

General consensus seems to be that the only advantage to a 5 lug conversion is a better wheel selection.

Quite a few people get the 300ZX rotors redrilled to the 4 lug pattern. Personally, it makes me nervous but I've never heard of any problems from the redrill.

You'll also need some custom lines to go from the 240SX hard lines to the Z32 calipers. You can get those at http://www.pdm-racing.com

I think Project Silvia also has some for sale.

Technically, you can't turn in your 240SX calipers and get the core charge back on your new Z32 calipers. People often do it, and the guy behind the counter will probably have no idea that you returned a part from a different car. So, I guess you can call it "tricking them".

Just to be a bit of a rebel here... have you considered upgrading your 240SX brakes with some really good pads/rotors? I run stock rotors (it's a rules thing), Hawk Blue pads, stainless braided lines, and Motul RBF600 fluid. In a typical 20-minute track session I have to threshold (max) brake between 24-28 times, from between 90 - 120+ mph down to as low as 25mph, and this setup gives me excellent bite with no noticeable fade. I would think for a street car if you went with a good set of drilled/slotted rotors, Hawk HP+ (or similar) pads, braided lines and a decent fluid it would be more than enough stopping power (for less than half the cost of the 300ZX conversion). JMHO tho. Also, something a lot of people don't consider, you can use the ABS rotors/calipers on a non-ABS car (you have to get the "loaded" calipers), and get another 5mm or so of diameter, and slightly larger pads.

I know the 300ZX brake conversions are the trick setup, but I just wonder if a lot of guys aren't spending more money than necessary to get these things to stop.

don't forget the q45 brake upgrade. costs less, and you don't have to get new lines.

ITA240SX, that is EXACTLY what I allready had planned when I wear these brakes out...for a street driven car I just dont need the fade resistance that the larger 300zx rotors could give me...a good pad, braided line, and maybe aftermarket rotor upgrade should be more than enough for me.

I was going to start a thread....this may be easier!!! Heres the story........ My rear driver side rotor is shot and i'm planning to move out of state in 10 days(pulling a 1,000lb trailer over the rocky mountains) so time isn't on my side and it has to be fixed before i leave. I have "stock sized" front cross drilled rotor/axxis pads/stainless steel lines. My chioces are q45 upgrade/ cross drilled "stock sized" or replace only the bad rotor in the rear.At what point is upgrading the rear rotors necesery???? Would using the q45 rear brakes cause a problem with a stock front set up?? I' need to make my decision by 3 pm on tuesday

I don't think you would get hurt upgrading the rear brakes, but at the same time I'm not sure how much you would gain over just a stock rear setup (remember the front does something like 70%-80% of the stopping). I'm not familiar with the Q45 upgrade, but the one thing you have to be careful about is moving the brake bias too much to the rear. Could get real interesting on wet or icy roads! The only thing I would strongly recommend is that you replace both rear rotors/pads - if one is shot there's a good chance the other isn't far behind it (unless there are unusual circumstances). You could get a set of stock brembo rotors and something like the KVR (or similar) pads for just over $100, and you should be set for quite a while. Then save your $$$ for that killer front brake upgrade.
