240z rear disc conversion

[red_dog007]

Well, umm... I have been hearing a lot lately about people doing a rear disc conversion in their 240z with the drums.

I am wondering if I should be looking into them myself. Will they give any advantage over the drums? Increase daily driving stopping power? How about when racing?

I need to change out my brakes all around here soon, so would it be much more to do this conversion then it would to be to replace both back drums?

Well if you are going to just do a brake job. The rear linings will run you about $35.00 for some good brake lining. If the drums are not scored or worn past the limit measurement. Also if the wheel cylinders are not frozen and are working OK then that is all the cost . OEM wheel cylinders will be about $75.00 each . The last time I checked the aluminum drums were about $75.00 at he parts store. For a Z not used for competition like Auto Cross or on the track. The stock set up is all you need . Other wise the disk conversion would be a wise upgrade. Vented disks in front and disks in the rear . this is not a cheep up grade. Maxima caliper mounts are available from your Nissan dealer, for less than what they are going for on EBay. I believe the dual piston calipers from a Toyota truck and 300zx rotors for the front is what has been found to be the conversion . I am sure others on this site have done this conversion . I have not. I think you should do a search on this as this has been a topic a number of times. If this isn't successful then start a new thread asking for information on the disk conversion specifically . Gary

I realise that this hardware may not be available to you in the States but, in Oz, a cheap, easy and effective rear disc conversion is done using the R31 Skyline callipers and rotors.

I have posted a heap of pics. about this on the following Sony Imagestation site: -

It is literally a bolton conversion, with minimum fuss:classic:

This hardware required is plentiful here so let me know if you are interested.

THANK YOU SOOO MUCH!!!

I will most likely be doing the rear disc convertion using R31 gear now, very VERY helpful, and I will give credit to you on the mounts.

Have you done anything with the fronts at all?

[Nissanman]

From your profile I can't determine where you are from but, the fronts are planned to be ex-Commodore vented rotors with matching callipers.

These bits go for a song when the factory upgrade a car to HSV specs.

The brakes aren't new but they are hardly used when the car is driven from the factory line to the HSV workshop!

The rotors (296 x 28mm) have been re-drilled for the 4 x 114.3 PCD and therefore are now "rotor over" as opposed to the stock "rotor under" design. Wheel studs have been replaced with 60mm Nismo items to cope with the additional 10mm thickness of the rotor. The callipers will need re-drilling to match the calliper mounting ears on the stock struts. They are twin piston alloy housings with a cast iron anchor.

Lots of pics. on my Imagestation: -

yeah i should fill in my profile more, I am from the Sunshine Coast up in QLD.

I am in the process of building up my 260Z, and the brakes could do with an upgrade at some point.

cheers for all the info and pics.

Sorry to bring up an old thread.

nissanman, do you have the pics posted anywhere other than imagestation (which is now closed).

can i clarify, were the mounts on the caliper redrilled, or the mounts on the strut?

and can i ask who sells the ex HSV cast offs?

What did you do about rear brakes to match? commodore rears?

Here is one place to try for the HSV cast off's

There are various ways to do this in the USA, but, there are complete kits available at Motorsport: http://www.thezstore.com/page/TZS/CTGY/PBC12

From what I can see, they have a few options ranging from a small kit with the brackets to a stage 1 and stage 2 setup.

I have heard you can put these parts together yourself but you'll still need the bracket.

You can get the entire rear setup, minus calipers, from Modern Motorsports. This will use the 240sx rear calipers. Silvermine Motors also has a setup for the rear brakes that use the 240sx calipers.

The front brakes you can also get from Modern Motorsports and Silvermine. MM only has the 300zx vented setup whereas Silvermine also has the old 4x4 caliper (nonvented) setup as well as the vented setup.

MSA is good for some parts, but you can save a bundle by piecing the kit together yourself. I save around $450 by piecing the 300zx vented and 240sx kits together, placing WTB adds, watching Ebay, etc.

I put the whole thing together by searching

1) Car-parts.com Vented Toyota Calipers($30 a pair)

2) Discount auto Rebuilt lifetime garanteed Loaded vented Calipers($110 a pair-$60 core)

3) RockAuto.com Vented rotors ($40 a pair)

4) Local Dealer Maxima Brackets ($110 a pair)

5) Ebay Spacers and hardware ($65 a set)

right at $275 for the whole shabang-all new/rebuilt parts
