Need a little guidance here,
I'm thinking of ditching the advised Caliper setup on my Phantom which is - Rover 400 43mm slider calipers using the original servo, original 827 back setup.
Replace with 4 pot AP calipers on floating discs with a balance bar front/rear twin master setup.
Do I need to keep the servo or would I lose feel? would this system be totally over the top and a waste of money (+/- £1500)?
Cheers Nick

You generally get more brake feel without a servo, though of course you also need to push the pedal harder.

Last time I drove a Phantom it had the latest drilled and vented disc option and they seemed plenty powerful enough for road use, so unless you're planning a mega engine or a lot of track use I'd say save your pennies and go for that.

The original set-up will be just fine, remember, it was designed for a heavier car.
Vented discs are supposed to be able to dump heat more quickly and that characteristic is required on the racetrack where you are either braking or accelerating. On public roads it just doesn't happen like that, and the ability to quickly cool red-hot brakes is wasted.

Thanks for that chaps, I will stick with the original and maybe swap to a front/rear balance bar master cylinder setup from Demon tweeks so that if the fronts are still too powerful (as Norman from Phantom reckons they are) then this should sort it.

I now have the Balance bar setup and its looks very well made.
One query though, the balance bar itself will be transferring the servo load to the Master cylinders under a "Shear" force as it starts at 90 degres to the cylinder pushrods. Will this be reliable long term? given that usually all brake parts are taking the load in compression/tension.
Anyone done a few thousand miles with one fitted?
