You want to make an "n" shaped billet bracket that bolts up on the inside face of the beam upright [you'll need to buy some longer replacement bolts for stub axle] then the other side of it just requires two clearance holes for the caliper bracket studs to go through.
oh and maybe make the new bolts shanked :)
Before the brackets get finally designed, I've got to think about the track width.Quote:

I can reduce this track increase a bit by machining the Mini stub axle further back.
But it's still going to be a lot wider at the rear than a standard Nova axle.
i love this car :) would like to go to a hill climb event, looking at the pictures in the link you posted there seem to be a real good variety of cars and bikes :)
could you redrill the holes in the original bracket to line up with the stub axle bolts, then machine the stub axle back to make the disc line up with the caliper? it would also help reduce the increased track
colin, if you shorten the stub, can't you redrill the caliper bracket to fit the beam??
Good progress i like the dedication to the cause.
A question.......
Is it really worth all this hassel to loose a few Kg off the car?
WIth the added problem of track width increase and potentially having to wide arch it isnt that going to add weight back on,
I know the standard setup isnt exactly brilliant but wouldnt all the money be better spent elsewere?
Tell me if im incorrect just posing a question :)
It is a very valid question!Quote:

It's also not costing me much to do, as all the machining and welding work is being done by my neighbour who enjoys helping out. I just pay him for materials, damage to his tooling and a drink for his time.
I have been thinking about wide arching the car for a long time now, so this will now force my hand, which is no bad thing as I may never have decided otherwise. It means I will have a wide track rear beam, and still be able to use sensibly sized wheels/tyres.
surely you can negate some of the extra track by modifying the beam
if you grind off the plates from the outside of the beam and weld them on the inside (red to cyan)
this will lose you 20mm overall track,
and then with machining the mini stubs you might be able to maintain normal arches

Keep the updates coming. Although i rarely post i do keep and eye on a lot of projects this being one.
I would love to see some video footage of the car competing :)
I was thinking the other day that this in the shell of your old red car with the carbon bonnet would be a perfect setup!
