6 pin knock-ons - advice needed

[KevinW]

Hi guys, first new thread posted here, although been lurking on and off for a while.
About to start a new car build and bitten by the authenticity bug.
I'm looking for some advice on knock-ons which are far more common your side of the lake than here in the UK.

Can anyone tell me whether its possible to fit a 6 pin knock-on wheel onto a jaguar (5 stud) hub (front and rear, same pcd though).

I found a thread that looked like ERA did something, but looks like a bespoke or replacement hub assembly (big $$$?), maybe only for the rears. Unfortunately i didnt understand everything that was written there by someone who seemed to have solved the problem with FIA wheels.

Hope you can help.

Kevin,
You can't do 6 pin wheels on a Jag 5 pin hub. You have two choices - replace the hubs with 6 pin hubs (Justcobras.com, about $850 for four) or use the very popular 5 pin wheels with adapters. Vintage, Trigo, PS Engineering, all of them sell tons of these, and from the outside they all look the same. Good luck, and welcome to the madness!

Kevin,

Welcome to Club Cobra!

As you know, Simon Finlay makes a replacement Jag hub for the pin drive rims. The ones he has made so far are 5 pin to fit the common wheel. But, his design seems like he could make 6 pin, 4 1/4" bolt diameter (or as needed) just as easily. The Simon hub is on the left; notice how it is shorther than the adapter system on the right, thus "narrowing" the front track an inch or more per side. (Needed for Jag-based kits.)


Then you could get 6-pin Vintage Wheels for the "all original" style setup.

Just an idea,

Larry

Thanks guys.

Doug, reason is I am thinking of using 16" knock-ons (have my eye on a second hand autocraft set). 16" tyres are far more plentiful in the UK than 15". but 16" halibrand knock-ons only come with 6-pin drive as far as I can find. Back to the drawing board.

I was thinking about that idea Larry, but i would still have a problem as simon's adaptors are only for the front - am I wrong?

would 15" rear and 16" front look stupid? :

cheers,
Kevin

Kevin,

Simon can do both front and rear hubs for the Jag setup. Or get Simon fronts and www.justcobras.com rear. That way you get the narrowed front track you will need; 6-pin, no adapters. Image of justcobras rear Jag hub:


Then you can order Vintage Wheels w 15" tyres mounted and balanced, so 15" tyres should not be an issue. They seem to last forever. For example, I have a set of Goodyear Eagle GTII w 6 seasons, 21,000 miles, about 50% rubber still left.

16" on one end and 15" on the other would not be the "original look". Some compromises to originality are generally made by us all. After a while, it's okay. Vintage has sharp 17" pin-drive rims, if that helps you.


Keep after it, Kevin...you'll find what you want eventually.

Regards,

Larry

Larry, How does one contact Simon? Do you have phone, email or website contact info?

woah daddy that's a low sidepipe.

There was a bolt-on adapter from Contemporary once which added a lot of weight and track in the front.
The rear used a similar setup as ERA's.

I can only advise to get a 6-pin set. Because you avoid a lot of trouble which we are busy solving here:

Pin drive bolts splitting Help Please

I also have a set of new 15" 6-pin wheels near Frankfurt/Germany.
The backspacing of the front MK4 are completely different than what mine have and you want.
I tried MK4 wheels on my RAM and they stuck out big time.

See Simon Finlay web info . You may have to PM him.

It is his personal business, not a major company. He is in the UK.

That FFR was converted to right hand drive by the builder and he had issues w the right side custom exhaust header at first when this image was captured. Since worked out.
