Brake upgrade to 330mm front discs
Discussion
Having just scrapped the MOT with my original discs and pads, I decided to investigate alternatives or a new set of the same. I came across the CL brakes and Mr Paul Chance. Because I've got the cerbera calipers 6 bolts I can go all the way up to 330mm! I've placed an order for discs and pads and they should be with me in the new year. So, seeing as the Tuscan is of the road and I still have loads of things to sort on the car, I thought I'd do a how to.....
So.. Jack the car up and remove the wheels.
Then, using an allen key/socket, undo the 2 bolts holding the calipers to the uprights.
Male sure you suspend the calipers so that there is no tension on the brake hoses.
Using a screw driver pop out the old brake pads.
Measure the old discs so Paul can supply the right caliper spacer:
Pending the new parts... that's it for now.

A heads up for those using carbon pads, if you decide, after a period of use, they are not for you, changing back to a more conventional pad is not straight forward. Discs will need to be ground.
Why wouldn't I get on with the brakes? What's the difference with cintered brakes. Surely they have a better initial bite?Edited by MPETT on Wednesday 1st January 16:05

CL Brakes are a sintered metal pad, not Carbon.You can change to another brand after without grinding, the original name of Carbone Lorraine is misleading i grant you that.
Here are the 330mm items that landed yesterday, i have spacers already for 322 upto 330mm for both types of caliper, new bolts to suit hopefully in Monday.

Ooooooooh they look lovely! When can I have a pair! You can change to another brand after without grinding, the original name of Carbone Lorraine is misleading i grant you that.

Discs arrived in the post last Tuesday as agreed.
Slightly bigger than the measley 291mm rotors!
The discs come with a protective coating so that needs to be romoved to allow the pads to bed in.
I'm going to try the old pads to see how they go and if they are pants I'll get the CL pads. I used a bit of emery paper and some flat wood to take the shine off the pad.
Putting them on was a doddle. Used a clap to push the pistons in. The bolt simply go through the caliper, then the spacer into the upright. Torqued up and we're good to go.
The wheels look much better. Minimal space between wheel and the disc
Money well spent!

That looks very good 
can't stand a car with big wheels and piddling discs.
Did you get a chance to weigh the discs before putting them on, interesting to know the difference.
The old 291mm discs were 7.1kgs. The new 330mm ones are 9.8kgs. The surface area has grown by circa 32% and the weight very slightly more. Considering the old discs had done 24k of use they were fairly worn and would have weighed a little more when new. All in all I'm happy. First test drive this weekend can't stand a car with big wheels and piddling discs.Did you get a chance to weigh the discs before putting them on, interesting to know the difference.
!!!MPETT your post has got me now researching this as just had the wheels re-done and agree that the bigger discs look good as well as improving the stopping.
I notice that Power are offering an upgrade 330 pack. Is this a competitive price or did you achieve your goal in a less expensive way?

Is that over 400 quid inc vat, for 2 discs, 4 high tensile Allen bolts and 4 Alli spaces as in the piccy, seems expensive to me. I presume, the discs are very expensive !!I notice that Power are offering an upgrade 330 pack. Is this a competitive price or did you achieve your goal in a less expensive way?

Tarox has the 322 mm ones (std Cerb 4.5) as a 2-piece disc - part # S2-2004, 799 euros a pair. Tarox aren't cheap, but very good IME (heat treatment, surface quality).
The 330 mm ones I haven't seen yet in a 2-piece version anywhere, although everything is possible if you have the dimensions I guess... at a price.
I'd say 2.7 kgs extra unsprung/rotating weight per corner is quite significant & I would do some soul searching whether I ever got the OE discs to wilt under my braking when using a good pad compound (CL/Ferodo DS/Pagid) before pulling the trigger on the huge ones.
