Questions regarding bolt-on hubs

I am looking into building my own locost(ish) running gear and plan on using bolt on hubs from an Vauxhall Astra (VKBA 5311) and making custom uprights.

I have been reading up on the forum, particularly this discussion regarding “New Locost front end design” (http://www.locostbuilders.co.uk/viewthread.php?tid=34017) but I am not getting any further.

So my basic questions are:

• Has this been done before?
• Any threads/links for more info?
• Is it possible to use the same hubs on all four corners of the car? In the front without CV joints. The bearing assemblies are gen 3 so they should be self-supporting?

Cheers,

//Carl

Yes they'll work fine on front without CVs in them. Plenty of tintops have gen3 bearings that way on the rear. GBS are doing that on their kits now and I think AB Performance are as well.

TVR used it too on the Cerbera onwards and actually Lotus used GM bolt-on bearings on the S2 Elises, IRC they just used an M12 bolt to replace the drive shaft.

Later Lotus upgraded M12 to an M16 with thick profiled washers.

Thanks for the input guys. Much appreciated!

I could use a bolt like suggested, just to be on the safe side, but it should not really be needed should it?

No, gen3 type bearings don't need a bolt through them. GM and others are using them that was.

I think it was Saab hubs that had the same PCD as ford wheels and weren't massively heavy.

Although I heard that you might need to machine the centres down to fit ford wheels.

If someone knows of a bolt on hub with a sensor built in (which has a ford pcd) please let me know.

Im talking 4 stud here.
