for the fronts im thinking.
Any links to said project???
Great idea it would be interesting to see how efficient they would be as then nova is more than likely 2-3 times as much as a bike weight wise!
If they are over speced for the bike they may be ok though
Bike brakes are single thin discs like the KAD brakes Colin has afaik, my guess is the guy with the fiat fitted them to the back the same as Colin... considering you can generate enough heat to fade 236mm vented discs and some people manage to cook 256mm vented on lower quality pads, moving to what is effectively thin solid discs that are designed for a much more open cooling environment and less than quarter the weight, would be a very bad move!
at a guess this Nova will be around twice the weight of the bike but remember that the bike brakes are designed for stopping from speeds of 160mph+ so the extra weight of the car will probably be compensated for by the slower speeds reached on a sprint track. Its definitely worth looking into but i would imagine some rather expensive custom machined hubs will be required to suit the bike discs and hold the calipers. And then a spacer will be required between disc and wheel to give enough clearance for the calipersQuote:

as you can see he has used the same thickness brake discs, and he calculated the area of pressure from the pistons on each caliper and the bike ones came in a little higher, so didnt affect the servo pressure.
and he says, the feel is alot more modern now unlike the old feeling.
IMO. it works like this, because its just a caliper pressing a pad against a disc. if you used small thin discs, then yeh there would be an issue as you mentioned
p.s note he spaced out the motorbike calipers to suit the disc.

Ah right thought you meant the whole setup, can't see how he's saved 6kg a corner without the lighter discs tbh, he's swapped a caliper for roughly the same size caliper as far as I can see?
it was going from a 1971 sedan to a 2008 Suzuki GSX R750
and my bad, 6lbs. stupid american! (2.7kg's)

more then likely im sure 2008 tech is better then 1971! lol.
and still better then 1990ish that a nova is.
p.s he doesnt have any fancy brackets or custom machined hubs!
If it's just a calliper swap as pictured surly ap or similar do a lightweight calliper?
yes but a decent second hand bike caliper will be a lot cheaper than an AP itemQuote:

i think they are the ones the guy used, and at 50 quid a side thats good IMO.
the guy mentioned in the states he picked them up for under 20$ i think!
That motorbrake idea is a contender for most stupid post of the year.
5mm thick disc Bike brakes on a car lmfao
are you blind? - not 5mm thick!
http://i459.photobucket.com/albums/q...frombehind.jpg
That isnt a motorbike disc?!
i never said it was lol.
you said that 5mm discs would be a stuipd idea, (and i agree totally)
but i have said no where he would use 5mm discs
p.s does he use 5mm(ish) discs on the back?
It looks like a 10mm solid car disc. You can see where the caliper has been spaced out.
yeh, the guy used his original spec discs, and spaced the caliper.
works fine IMO. and saves weight.
Only because they are lightweight calipers, so if you really wanted that weight saving with a proper brake setup (solid discs does not = proper btw) then you buy a set of decent quality alloy calipers.Quote:

So my statement about post of the year stands.
im sorry i havent, please quote where i have said that!Quote:

Sure i read the other day some of the most competitive (track) fwd cars run no rear brakes to great success in one of the race series's :)
This is obv no help, but shows how different and crazy the rules are at times
most of the fiesta racers used to blank off the rear brakes until they got caught...
but on hillclimbs, surely the use of a handbrake would be very useful....
like to park it on the line ready for the off etc...
Please note after all the argueing... lol that the disc is a solid car disc and the caliper has a machined spacer (silver section in the middle of the caliper) to allow this to be used in combo with the disc. To me this is cheap and not really the "Proper" way to do things but if its all he had and working to a budget and works for him in his circumstances then go for it...Quote:

I can do this... I can make my own vinyls as well... They not uber fantastic and aren't huge but I can do some headlamps if you wanted? Just got to find a half decent picture of said headlamps lolQuote:

Or you can email them to me whichever is good lol, by the way if you put them onto the car then you will definately need some UV Lacquer spray, otherwise they will fade or wash off in the rain, that's happened to me before where I did some vinyls for their motorbike and didn't put any lacquer on it, then went through a huge puddle and it all washed off on one side
The rear disc brake conversion is now all tacked together, complete with caliper mounting brackets.
I need to trial fit it on the car now, and see how it all looks/fits.
We machined down the stub axle and mounted it differently which should mean the track is only increased by around 10mm each side. But we will see better when it's bolted to the car and a wheel is fitted!

Very nice colin
Nice work dude, I'd love to see this for real, is it going to be making an appearance at Billing next year?? I'm hoping to be going there with my nova, it "should" be done by then lol
Yes, Billing is definitely in my diary for next year.Quote:

Possibly the widest arch Nova ever?
I probably won't be using the arch kit as it's just a bit too wide, but there were composite doors, bonnet, tailgate and some moulds in with it, so it had to be bought.
nice one colin,
keep up the good work.
Did you get the Kev sign from the front as well lol
Just read through this whole thread. In short, this car, and the work going into it is brilliant :)
