rear inboard brake upgrade?

[kestor]

Well, actually a couple of questions about changing the rear inboard disc setup to a vented rotor and possibly changing to a more modern caliper

1) is it worth the cost
Since I'm going to have to refurbish the whole rear setup, including the parking brake, why not change to provide better cooling and easier future service


2)is it worth the hassle
There are surprisingly few options out there to upgrade to a vented rotor. Would it actually improve braking and cooling of the differential rear seal (most of the stopping/braking comes from the front.

In the US I can only find upgrades from XKS (not for the XJ6 differential?), Terry's Jaguar, and JHE (going out of business?) and possibly Rob Beere in UK

Here's a couple of pictures of the parts and the end results. Ideally the picture that has the AP caliper setup would be fabulous!!
What do you think??

For a car as light as the wedge I’d struggle to justify the upgrade cost. They look great though

Having just done mine, a standard refurb, braided hoses but will be having grippier pads

I have seen one wedge with this upgrade which is one of the yellow SEAC racers.

(Yes I enjoy scrabbling around underneath wedges at rallies).

That's probably the only car that really needs it, the rear brakes don't do much actual work and as you say a wedge is a light car.

Have raced a wedge for 3 seasons, with standard rear brake setup, I would so no it's not worth the expense, I do have ducting to them and a brake bias that does help, as I have boiled the rears on the 400SE on a track day, and also on the road due to a sticking caliper.

So a more cost effective route would be to keep them serviced and add some ducting to aid cooling if your getting a problems, its very rare to cook them though if they are in good service.

maybe it be better to fit a 8inch fan over them, that way you can switch it on when you do fast driving?and it keep the diff cool as well,
