Hey there

I was wondering if you guys know if the Billet II Caliper range from willwood fit the Cortina upright?

also what is done for the rear?
what do you guys use to convert to disc rear ends

Rally design (raldes.co.uk) sell a kit to put wilwoods on the front cortina uprights. generally people only bother with uprating the front as it does roughly %80-90 of braking and the back will be ok with drums, though there are ways of modifying the live axle to accept drums, I'm sure someone will be along shortly with a link. the alternative is IRS and use the sierra back end with discs or autrallian equivalent.

Ned,

I don't think you'll find the proportion is that high - that sort of figure is what you'd expect in a FWD car. In a locost, especially in a tail heavy BEC, the figure is likely to be closer to 65-75%.

Thing with the wilwood calipers, they're light - I'm going for the 2 pot dynalites - the calipers are just 1.4lbs weight each, compare that with your cast iron monsters. I'm also going to go for non- vented discs and alloy bells to save more weight, sounds flash but it's not too bad money for all new kit (calipers about £50 each). In my opinion you only need big vented discs and 4pot calipers on a heavy car... we'll see how it goes!
wrt braking split front/rear going for up to 70% front should be adequately safe - Istarted a thread a while back about height of centre of gravity so I could work this lot out on XL, I concluded 16" up from considering the major metal bits of the car (of which I was the biggest single contributor at 105kg...). If you overdo the front bias it seriously reduces your braking efficiency on ice/snow when you need it most.........

PS I'm not using cortina uprights so I can't help you much

You may get away with the 2 pots, you will be safe with the 4 pots as I race on these.

You need an adaptor for the Dynalites for the Cortina hub. See Here

Impressive mount

this isn't for a road car...

I was thinking of a datsun 1600 rear end?
but I just am too lazy...more poo to break
ect

thanks for the info guys
