I started following these yesterday, I set up with a proxy bidder and made a deposit but it still will not let me bid on them. I will continue to try but in the meantime I know someone has  a set here in the US. Thanks JLP

Hi Jerry, seems to me this one is original Sumitomo licenced MK63  ,http://page10.auctions.yahoo.co.jp/jp/auction/m188011442

The seller says they are for solid disc roter . This means it is easy , just replace and install (need to cut baffle plate little bit though).

The other one is aftermarket( not Sumitomo licenced) , so the price is not high for the ''buy it now'' . I recomend stay away from this aftermarket , you will find a good used Sumitomo one just adding little more money.This one is for ventilated disc roter.

I think there are several versions of MK63 (Sumitomo logo on it )

#1 sold by Nissan/Datsun as a sports option for S30 from late 1969 

#2 original equipment for Nissan President (big saloon for excutives) ,a bleeder pipe is pointing outer , so you may have a 15 inc. wheel or a spacer to avoid scraching the wheel.

#3 sold by NISMO (discontinued in 2008)

#4 sold by Victory 50 or some owners clubs after NISMO discotinued, manufactured by the same company which was making for NISMO. The last batches are painted silver.

Still overhall kits are availavle,

Thanks Kats, I have been trying to bid on the first but after making a 20,000 yen deposit through a proxy biding company (fromjapan.co) it will still not let me bid on any of the MK63 yahoo japan auctions. I had a set of these on the front of my 1970 race Z. Vin# HLS30 00029 back in the day. They ended up on the rear after we updated the car for IMSA in the early 80's. I contacted the current owner to see if he would sell them back, but have not heard back from him. It is very difficult to bid on auctions in Japan.

Did you use the sniper bid option by any chance? If so, it wont show a bid until near the end of the auction.

I've used fromjapan.co personally and have had good luck with them.

 

You can email them and they are pretty good at replying back.

Probably rejected your bid because of the brake fluid.  It's considered hazmat and cannot be shipped by air.  I'm going over in june and can bring them back in a suitcase if they're impossible to find here.

Thanks for the offer, I may have to take you up on it. I will just have to buy rebuild kits on Yahoo Japan and try and find the MK63 elsewhere at this time. Thanks again. jlp

Jerry - given both the rarity and price do you plan on putting some serious miles on these calipers? I guess the better question would be will you drive your Z less if you install them?

I was told that a Toyota SW could be massaged, by that I mean machined, to look very much like an FIA caliper. Vintage racers might have done this.

You could swap the real ones in for a show, etc.

I updated my oddessey post a few hours ago with my plans. The car is, from new, not considered stock. It from when I purchased it new had Datsun Competition parts on it. Spook, mirrors, wheels. It was restored keeping those parts. Since realizing the the restored car cannot compete for a gold medallion I have decided to finish the period correct Datsun Competition theme. I have and plan to install a original Datsun Competition Racing Suspension kit and the FIA (MK63 calipers). I had a set of MK63 Calipers and mistakenly let them go with the 00029 car. I am also wrestling with having Dave Rebello build me a purist engine next winter. Then I plan to flog the car!

I'm still looking for a set of these to reverse engineer and make in alloy. Here is a set of Porsche 914 calipers I did the same with.

 

They would be about 4# lighter per side and use larger fasteners to mitigate any flex from the lighter material. It might even be possible to add a spacer for vented rotors.

I run MK63-20S vented type calipers on all my cars. I have a spare NOS pair new in their boxes, but don't really want to sell. I might - however - be tempted by an interesting trade. Have you got anything that you think I'd be interested in...?

I don't know what you might be wanting or needing. I have as you have seen a early OHC 2400 valve cover, I have an early rare front core support seal that goes between the core support and hood to limit the air going above the radiator. I have a 4 core radiator ready to go. Original NOS set of inner scuff plates lots of yellow zinc plated parts etc....Hopefully we can make a deal I am on a mission. Thanks Jerry Purcell

You bid on this brand new set and it wouldn't let you?  If that's the case then i don't know why. There shouldn't be any residual brake fluid inside.  You can try buyee.  Maybe they will let you bid.

Yes.

Those are the recent repros. Not original Sumitomo.

Generally speaking, originals will have makers name 'SUMITOMO' cast into them. The repro guys are not allowed to incorporate the Sumitomo name on their version...

Thanks, but I'm OK for all that stuff. I'm more interested in original Nissan 'Sports Option', Datsun Competition and genuine Works parts...

Since MK63s have a reputation for flexing at extreme pressures, I can't imagine how you could engineer accurate lookalikes in alloy without changing the design enough to make them not look MK63s any more...

You might as well buy the ENDLESS S4 MK63-replacements and paint them green, or just go AP and done with it.

ZCCA has two classes for their "Gold" awards, stock and everything else, with stock being the hardest to achieve since not only does your Z have to be pristine in appearance, it also has to be completely stock or you lose points.

Cleanliness is next to winning in all the other classes (street mod, Nissan mod, ultra mod and daily driver). Doesn't make a difference if you have a purple painted engine block with yellow stripes, if it's clean and undamaged judges can't deduct points. Now paint drips, orange peel, missed spots, those can cost you points. You might want to reconsider or maybe just go out and flog the thing....

I show  my parts just for your reference, 

Nissan released solid MK63 first , ventilated later (I think factory racers already used well before listing in this catalog, sports option parts Dec 1973) 

Funny thing is , race and rally manual issued Feb 1970 described only brake pads for "brake section" , it did not mention about MK63. Very first cars were racing with stock caliper , stock caliper is not so bad !

Hi Alan , it is the most difficult thing for all of us to make you interested in . A seller of LY engine would be the one for you.
