Don't worry, John, It looks rather impressive to me!

I recon a really useful idea would be to put each type of caliper beside each other, photograph, and then decribe what they're fitted to as standard. Maybe even what they would each fit as an upgrade and what it would take.
So then. Has anyone got one of each type of caliper to photograph? [8|]

Big? Big! About sums it up.
The discs arrived today, delivered in two big boxes. That confused me. I was worried two orders had gone through. But no! The reason it was one disk per package is a pair is too heavy for one man to lift [

I weighed the set up:-
2 Nº 964 Turbo discs
2 Nº big black callipers
4 Nº Red Stuff Pads
8 Nº anti squeal disks
29kg ...4½ stone in old money []. Granted they were still in their respective boxes, but that made up for the missing brake fluid. I'm glad I bought holy discs as the others would weigh more.
The individual weights:-
1 Nº 964 Turbo disc = 9 kg (1½ stone)
1 Nº big black callipers = 4 kg
4 Nº Red Stuff Pads = 2 kg
It's a shame I haven't still got the original 220 Turbo brakes, just to see how much unsprung weight I have bolted on.

Unsprung weight!

Or have you developed an "inboard disc" solution a-la Lotus 72? []

Don't be silly Mark, that would then be sprung - the car is sprung, as in it is supported by the springs. The wheels, hubs, discs, callipers, lower wishbone (in part) are not held up by the springs so they are un-sprung.
Unsprung weight is far worse than sprung weight because you can't do anything to damp, or adjust, it dynamically.
But then you knew that really and was only making the point so that I could explain it for those that didn't know.

I thought that's what I was meaning (?)

And here's the after (sorry I don't know how to post two photo's on one post). Actually, believe it or not I don't think there is a massive difference in overall weight. By my 'human scale' measure there is very little in the calipers. I would be surprised if the weight difference was as large as say going from 16" wheels to 18" wheels - and that effects all four wheels.

Most Westy owners go to 13" wheels as against 15" when sprinting as the turn in is quicker and less gyroscopic effect on the `lighter` steering. Losing weight ie: lighter wheels also helps to reduce this effect. Heavier brake callipers will not make much difference but heavier reciprocating discs will.
However I`d love the option [8D][8D]
Jon are they the ones you got recently at a `good` price, if so you lucky person (not jealous)
I'm not unhappy with what I paid for the callipers - and as Fen said - others can be happy as well. However, by the time you add discs, pads, bolts, fluid, squeal shims (and radial mounts if you don't have Turbo SE struts) you are talking well on the way to £1,000. You also need 17" wheels.
