New rear hub design .

Wow!  That's a little on the spendy side of things, roughly $4550.00 USD for a pair. 

And, I'm surprised they are using 5052.  I would have thought 6061 would be the preferred alloy as it's heat treatable.

JB - Thanks. I look forward to your write up!

D'man - at $4500+, I think I'll pass. They are pretty, though.

I haven’t got that much in total on mine yet.

I think that's a pretty good indication of just how Europa-crazy the Japanese are!

Hi,

Sorry for the late contact!

I received a reply today and I passed it on completely below.
I also conveyed an invitation to our site and interests.

In the case of lotus europa sp rear upright,
 The production is requested to a company that produces Honda's formula one vehicle, prototypes of HRC such as Motogp, etc.
 The data of lotus europa sp genuine upright is generated by a three-dimensional measuring device, and after data correction, the material is A5052 and is cut by a 5-axis processing machine and finally finished by hard alumite.  .

 It is a price, but it will be 500000 yen (excluding tax) with the left and right set in Japanese yen.

Regards,
GARAGE TOPYARD,

That's $4,562.02 just in case anyone was curious !!

Just as I thought, made on a C&C machine. The first one is always expensive due to engineering input into the computer (although a laser would copy an original fairly quickly). After that they can knock these out fairly quickly with only machine time and then threading for the bolts. Couple of sacrificial prototypes to adjust the details and then full production.

Kelvedon sells them as well at £645 per side.  Not cheap!  But much cheaper than the Japanese ones.  Kelvedon also sells new cash radius arms with a removeable side plate so you can remove the upright complete without having to pull the spindle.

JB, I can’t wait for your upright mod . The spacer your picture shows a beast compared to what’s installed in an s1 and s2 . Dave bean parts book has a good guide on rebuilding them. I will need to measure them for the 2 1/8 nominal call for .
 What part did you sleeve on your upright? Are you using the same inner and outer bearings, seal and slinger?

[jbcollier]

The bearing bores on the upright were oversized and steel sleeves pressed in.  With the change in yokes, no seal or slinger.

[dakazman]

Now I see it.
Will it work with drum brakes or just rear disc brakes?  I have some time before I start going down a modified system but I’ll keep waiting.

It will work with the stock drum brakes, or any disc kit meant for the Europa.
