Does anyone know where i can buy new monty ventilated brake discs.
Both front and rear.
I have tried a few places but no success.
I am going to use them on my 72-gtv bertie.

Thankful for help

There are are set of new rear rotors on Ebay now.

G. Häckner in Germany sells ventilated front brake discs for the Montreal, but they cost a bit: EUR 278 per pair.

They have rear discs too, but they're not ventilated. The Montreal only had ventilated discs in the front originally.

Just a minor correction: The Montreal does have ventilated discs on both the front and rear.

On my Montreal I use BMW M3 vented rotors on the front which have been machined down in diameter to fit. But... as I am also using alternative callipers I didn't need to reduce them as much as would be needed to get them to fit with the original callipers.

But this might be a possible option for you to have a look at as the rotors from memory were very reasonable in price.

Greetings,
I was advised that Colman Racing www.colemanracing.com could manufacture rotors, given a sample or the proper measurements, at a not unreasonable price.
Have as yet, not used their services.

Otto, I forgot to ask in my post why you would want to use the Monty rear vented rotors? for a start they weigh a ton, and in my case on the car they struggle to get up to and maintain race temp (especially on long straights) to use racing pads so I have to use a different compound in the rear, which for the first few laps heats up at a different rate than the front so I have a different feel in the rear bias initially.

I would swap them for some lighter soild/drilled rotors but with so little weight on the rear of the car anyway I've decided that the car needs the added weight for traction assistance over any possible weight reduction benefit.

But there again I've been know to make the incorrect judgement at times, plus your bertie has more weight in the rear than my Monty, but is another factor for you to think about anyway.

Regards
Phil.

Oops. Don't know where that brainfart came from since I'm in the progress of rebuilding my Monty brakes right now.

Sorry.

Anyway, I got a tip today that the Volvo 240 series callipers will fit on the 105 GTV with a couple of modifications. Maybe it's worth checking out if their ventilated discs will fit the 72 Bertone. Some had ATE and some had Girling.

For what it's worth, my GTV race car had Montreal discs on the front with Coleman calipers. Since the rotors were at minimum thickness, I checked into replacements. They were >$600. Next I investigated having Coleman make custom aluminum hats for the 2L hubs to match their standard types of vented rotors. The hats alone would have been >$500. Ultimately, I decided to go back to the stock type solid rotors. When I have raced with them in the past, they seem to be fine, as long at they get some good air flow directed at them.

John Newman on the Montreal mailing list is organising a new production run (with Disc Brakes Australia) of Montreal ventilated front brake rotors. Price will be around US $70 per disc. His email is otas [at] earthlink [dot] net. Contact him if it's of any interest.

can you give me the diamentions of the rotor that you need, the diameter, the height of the rotor, and the centre bore....from what i remember, the front hub is very much like my spider front rotor/hub....i am running vented front disk and 4 piston alum. calipers on my spider...i think i might have a cheeper rotor for you...

Check out Bisc Brakes Australia web site they have the fronts listed either as standard or high performance slotted and drilled. WWW.dba.com.au

Vin
Would be interested in a set, do you have the slotted and drilled ones?

They are also listed on Afra.it.
Like to catch up with you about the GTV6

Cheers
