2.6's too :y

At the York Meet a couple of years ago, The Master found that someone had fitted none vented rear discs to Mike Dundee's car. His pads were low which were fitted into their vented disc calipers.... the pistons if I remember correctly pushed out :o

Yes. All 2,6 and 3,2 have vented rears. Oddly enough, have seen one or two instances of 3,0 car having vented rears, cars were made late 2000. Very strange ones.

But, generally and with more than 99,9% odds vented discs only on 2,6 and 3,2 :y

Can the discs & calipers be retro fitted to 2.5/3.0 ?

Yes, but what would be to gain? Solids give well enough of braking power

Just a though so when I rebuild the rear end it would just be a nice upgrade as there's so many 2.6/3.2's scrapped it wouldn't be an expensive job

nothing on Omega gives anywhere like enough braking power. The braking performance I find truly shocking.

the vented rear setup is of the same dimensions as the non-vented, with the following exceptions :-

wider disc
wider spacing between the two halves of caliper
bigger diameter caliper pistons ( 42mm instead of 40mm )

ive found if the system is looked after. bleed correct and pads/discs all good stops fine.  if your compering it to a large performance saloon then it is a bit woefull. the police found them ok but they had new pads about every 6weeks and discs every year.
