Thanks for the support guys -progress has been slowed by the dreaded "Manflu"! - however I have picked up a couple of useful parts and am in the process of modifying them to suit the 6C. I will post some pics in due course.

Nice, isn't it?
The hardest part of fitting bigger brakes to a car is always the adaptor bracket for the bigger calipers - the brackets almost certainly never exist off the shelf! Having said that, they can be simple to make with just a flat sheet with 4 holes, however things get complicated when the offset needs to be adjusted.

Nothing is impossible with the correct tools

Regarding Callipers-
I have used the Rear callipers from the 164 with a simple adapter plate cut out of 1/4" steel to mount it on the 164 front brake plate. This has given two benefits -
1 a working handbrake
2 Reduced braking force at the rear (compared to the original front braking force) The original 164 front brakes would result in the rear wheels locking up as the weight transfer is going to the front and so the smaller calliper will reduce the braking force at the rear. Obviously this may need some "tweaking" when the car is up and running but it seems to be a sensible, cost effective initial solution.

Looks really nice. If it were me Id have ground off the porsche logo on the caliper, aside from that its perfect. Fiat Coupe discs are a perfect fit, even the offset is about +/- 1mm of the stock 33 vented disc! If you can find the pictures from the process that would be great. What was the adaptor made from? High strength steel? Are they 16in or 17in wheels?

Alfasixnut, I think you need this upgrade up front on your project!

Hi 77Sudti
I will be keeping the stock Sprint front brakes as I will not be needing fade resistance for the type of driving that I do - it is not a track day/race car that I want to build. Also, with less weight on the front, more powerful callipers would lead to the fronts locking up too easily.

Good thinking

As for the 33 "Porsche" my friend had to use a... I don't know the technical term for it in english, that piece of metal on top of the brake disc, to push the wheel outwards, so it didn't hit the calliper.

The material it used for the adapter I don't know yet, but I will find out.

The wheels are only 15in...

I will eat my hat if this vehicle gets roadworthy compliance!

While the front end does have less weight, I would have thought you would at least install the larger front calipers from a 164 or GTV6 - a pair of 4 pot calipers from a late model GTV or Fiat coupe would be an even better choice as they will give better stopping power and weigh less than the stock sprint calipers!

Keeping the sprint calipers to avoid brake lock up is just ridiculous - you need to consider brake bias between the front and rear brakes to avoid this - especially since you now have a hefty V6 engine in the back end. You'll still be relying on a lot of front stopping power when approaching a corner to turn in correctly.

Your intentions are awesome and enthusiasm to be commended, but all I can say is: good luck

Thanks Benjamin and tflg
My thinking is that if I can lock the front wheels with the Sprint brakes then that will be as good as I need - It is not a track car or rally car, and I do not drive like a looney, so fitting big front brakes will only reduce the non existant fade problem, the tyres will be the limiting friction factor and I will not be fitting big wide front wheels.
The overall weight will not be much greater, as the V6 is an Aluminium block and the boxer was iron. The rear brakes, with the 164 basis, will be much more powerful than the old Sprint Drums so the system will be improved considerably. I will, of course, be assessing the performance of the car in small incremental steps once it is built.
....and I hope you have a tasty hat BudweiserSud!

The most easiest mode is front calipers from 33 16v just to have vented disks....

Thanks Greek
Is the 16V Calliper and disc a straight swap onto the Sprint hub? I will keep this idea as "Plan B" - if the sprint brakes prove insufficient in the future.

Well after the snow, I've been able to make some more progress and wanted to actually see a difference so I've been bending, cutting and welding the rear louvres which make the 6C so distinctive.
It's only tacked in place so that it can be "fettled"

Yes it is a straight swap with no mods.....

Thanks for that Greek - If I see a suitable 33 16V breaking I may well get the parts - just in case!!

I've done a bit more work at the back of the car and made a start on the taller rear 6C spoiler.
I've also got my petrol tank back and will be making the mounting brackets over the next few days.
