a while ago i managed to get some of the REAR bbk brackets for the third gen.

ever since ive been trying to get ahold of some of the FRONT bbk brackets and am having no luck.

I know Blehmco used to make a kit that worked on 3rd-5th gen cars, so ive been searching those classifieds as well but havnt had any luck.

is my only chance to find some brackets from a member parting out here?

are the blehmco brackets the only ones that work on 3rd and the other gens?

I found one that said it was for a fifth gen, but that the brackets would work for s13s as well (dont know if this was accurate or not) and am just wondering how universal any of it is.

I want to use the z32 calipers and 6th gen rotors, but if I have to use the cobra rotors I wouldnt mind I guess.

thanks for any info

DMad thanks for creating this thread! I've been meaning to post something about this but I haven't been on the 3rd gen page much lately.

The short answer is "Yes" there is a bbk upgrade for the 3rd gen. There are some sellers on ebay that sell a bracket for the 240 (s14) to use the z32 TT 30mm aluminum caliper and the 350z Track Edition rotor (12.75") - this is what I used.

I don't want to take over your thread but here's some quick pictures:

Nice! And something tells me thetrack edition rotors weigh less than the 6th genners. I did an eBay search, I take it your brackets are blue?

Thanks for sharing

Mine are just bare aluminum. I remember seeing the blue ones but they were like $10 more. The track edition rotors are just bigger than the regular ones, which are the same size as the maxima rotors but don't quote me on that. Its been a while since I did all the research. I do know that all the weight I saved with the aluminum calipers and BBS rims I made up for that with those rotors... they are very heavy!

I want to point out to everyone reading this: I had to grind on the edges of the calipers. It's hard to explain but it was either that or machine the outer edge of the rotor. I went with the caliper because it was a one time thing and only about a 1/16th - 1/8th of an inch. If you think about it, the z32 caliper was originally designed to fit over an 11" rotor but since I'm using a rotor that's almost 2" bigger the edge of the caliper rubs on the outer edge of the rotor. This picture I stole from http://www.importnut.net/300zxbrakeswap.htm shows where I did the grind off, I circled it in yellow:

This a better picture showing where I did the grind off. The yellow triangle shows approximately where and shows how close it is to the bolt holding the caliper together. I just widened the arc a little bit:


I bet if you use the 6th gen maxima rotor it won't rub but you will get some pad overhang. Anyways... here are some more pictures:


this one shows the caliper after I did some grinding


this one shows how the edge of the pads line up with the rotor. If you use a smaller rotor this is where you'll see pad overhang.


this is the bracket I used

I have more pictures somewhere but I can't find them right now. I've been wanting to take the rotors off and paint the hats because they are rusty now and that doesn't look so good. I also ended up getting some extended studs and some 12mm hubcentric spacers so I could use the BBS rims. They were originally from a early 2000s Toyota camry se (18x7.5). I had to roll the rear fenders a little too.

Damn looking at your red Z32 calipers makes me want to take mine off the car and retouch the snot out of them. Im using the Blehmco brackets and SS brake lines.

marke

iTrader: (7)

Yeah, I got ss brake lines and the bracket that are both marketed for the 240sx. I just used some caliper spray paint from auto zone, VHT I think and it's held up well.

DMad8724

iTrader: (4)

OK. So I found some z32 calipers that I'm going to pull the trigger on. Get the s13 brackets and lines and I'll have to decide on which rotors to use. Marke do you know if the 6th gen rotors will work with this setup? I had a hard time finding track edition rotors that aren't cross drilled etc or aren't expensive.

I'll be putting this all behind track edition rims. I'd just rather not grind the calipers if I don't have to. Does anyone know the stock rotor diameter of the top of their head?

Dmad, you may already be aware but are you making sure to get the 30mm calipers?

DMad8724

iTrader: (4)

yup 30mm aluminums..all i have to decide is what color to paint the calipers. gloss black rims pebble beige car…hmm

btw marke what springs are you sitting on?

marke

iTrader: (7)

I think the 6th gen rotors will work. IIRC they are 320 mm and the 350z Track Edition rotors are 324 mm. They are also known as the "Brembo Package" for the gold Brembo calipers.

I have suspension techniques springs and swaybars (the lime green edition lol). That green plus the blue Tociko struts is why I painted the calipers red... to make it all colorful.
Also, if you haven't ordered the ss braided brake lines yet, some sellers offer different colors, I just went with clear though.

Another alternative are 94 J30 or Q45 dual piston calipers, torque member, rotor and pads! 3rd and 4th Gen's will have to loose the front brake dust shield! Good part is that Oem 5th Gen 17" SE rims fit trouble free!

marke

iTrader: (7)

I had some 02 GLE 17" rims on my car for a few months. They fit fine with the spacers. I think I spent more $$ on spacers, extended studs and lug nuts than I did on the calipers LOL


The J30/Q45 calipers are a worthy upgrade but they just don't have the WOW factor that the z32 calipers have. More people have noticed my car since I did the brake upgrade than anything else; but really it is overkill. I agree with the 3rd gen gurus that say all you need is a good set of brake pads and I would add to that, ss braided brake lines. To me, those are what I noticed gave the most brake system improvement... just my 2 cents. I'd like to get a nice set of light weight 2pc rotors and my BBK would be complete.

Nice setup BTW^^^ The J30 dual piston caliper give a wow factor when driving with good pads and Xdrilled/slotted rotors...But yes the visual asthetics for the 4 piston caliper really catch the eyes of those into extreme hardware!

What kind of shocks/springs/suspension parts/rims are those?

juggalo_g

For your steel braided lines did u make them,or was it a direct replacement for z32 lines with the calipers

marke

iTrader: (7)

The brake lines were not exactly a direct replacement. The 300zx came with a small hard line on the caliper. The ss braided brake lines I got eliminated that line. The sellers I've seen on ebay mainly sell them like that but if you know all the technical terms and measurements someone can make them for you exactly how you want.

Thanks! Yours is similar, correct? So you probably know that this setup makes our cars fun to drive!! I favor it over my 02 GLE sometimes lol.

Mine is exactly the same suspensionwise; Eibach springs though. Do you think your car feels too stiff on rough roads? On smooth roads and on the highway mine feels nice but I cringe whenever I approach side streets with potholes and divots.

to chime in on the topic, I have the Z32 caliper/Cobra rotor front and stock caliper/Z31 rotor rear

juggalo_g

Thanks marke !

marke

iTrader: (7)

I actually had Eibachs on the rear, to give it a lift, but I didn't like it, lol.
Anyway... I do feel every bump on the road, but I wouldn't say it's too stiff. I'd say it's a very controlled feel. I've learned to avoid the streets with potholes in my area and go slow over the railroad tracks. When I go on my commute in Atlanta I also cringe when I get on a surface street. They are horrible and it seems like they are so narrow. The interstates and state hwys are pretty good.

Found an ad in my area with these parts and was just curious about the z32 brembo rotors. Would these work with the z32 calipers on the 3rd gens provided i get the brackets marke mentioned for the 240?

marke

iTrader: (7)

No. The bracket is made so you can use 350z 12.75" Brembo rotors that are part of the "Brembo Package" which also includes the gold Brembo calipers. Brembo makes rotors for all kinds of cars but that is not the same as the 350z "Brembo Package".

so i got my z32 calipers the other day. when i purchased them i was confident they were 30mms but as I waited for them to show up and kept looking back over the ad I'd convinced myself I messed up and got 26mms.

well when I got them I opened the box and measured it and compared to the importnut pictures and was pretty sure it was a 30mm version.

just today I pulled the other caliper out of the box and could tell a difference right away. after comparing that one to those pictures im convinced that one is a 26mm version.

my digital caliper is reading 30.2mm gap on the one, and 32.8mm gap on the other.

supposedly im looking for 34-35mm according to what im finding when researching. did anyone else have trouble determining what calipers they have? because im convinced i have one of each.

also one of my calipers says "2" next to "SUMITUMO" the other one is a "3"

How are you measuring? For what it's worth, this is what I get on my spare 30mm calipers.



Regardless, if you're getting over 2mm difference between calipers on back to back tests you clearly have something going on there.

Where did you buy yours?

My set I currently have on my turbo car are actually 26mm units that were turned into 30mm units by using spacers in between the two halves of the calipers. I bought them from O'Reilly's. I was kind of annoyed by it when I first noticed it but they operate flawlessly. It's pretty clever, really to use that spacer. I figure the rebuilders have to do that since the 30mm units are in such short supply.

James92SE

iTrader: (31)

Wait a minute. After I posted that I noticed that picture above showing ~35mm for the 30mm calipers. I went back to the attic to measure my other spare set that I snagged at the JY some months back.

This set measures ~35mm.



That means the set in my first picture is a 26mm set!

I bought those from somebody on this site years ago. I can't even remember who it was now but what an MF'er. I was clearly told at the time they were 30mm units. That bastard.

DMad8724

iTrader: (4)

James. Thanks for the post!

I'm using the same digital caliper as you. I measured again and its still 30.2 on the driver caliper and 32.x on the passenger side. I'm thinking these are both 26mm versions. Which sucks because they are either relatively new or rebuilt. I could put them on without having to worry aboutpainting them or anything.

I saw a picture of those spaced calipers in my searches thru the advanced braking forum. I wonder if its something I can get ahold of and install because I'd really like to use these ones.

Thanks for the pics..with the forum being a ghosttown i wouldntve known. Got them from ebay and i was ready to tell the guy he sent me a mismatched set lol.

Dmad, sorry about your issues! I got lucky and found someone local selling newly rebuilt calipers and all new hardware and pads. He had receipts too, which had the correct part numbers. I don't have a micrometer so I would've never known if they weren't the 30mm ones.

DMad8724

iTrader: (4)

well, i found a site online that will send me some sample sheets of different thickness plate-aluminum. the thickest being about 2mm. so im thinking i could make some of these spacers, but theyd have to be at least 2 sheets. looking at the importnut pictures it looks like id have to drill 2 holes for the bolts and 1 hole in the middle for fluid.

its less than 10 dollars for the samples so im gonna give it a shot. i wonder if i can just use a 2mm sheet on the caliper thats reading 32.8…ending up with 34.8. its just wierd that the calipers have noticeable different widths

if anyone has opened their z32 "halves" id love to hear from ya..

James92SE

iTrader: (31)

Why not just buy calipers from O'Reilly's or someplace and turn in your current ones as cores? Parts desk jockeys won't know any different and evidently the rebuilders have no issues with it with their spacer bit like the ones I ended up buying. Actually, now that my memory is more clear - only ONE of my calipers has the spacer. That's what bugged me more actually that they don't "match" lol
