Triumph 2000 Mk1 brake upgrade?
Discussion
A mate has a Triumph 2000 MK1 which will be used as a track car. Engine, suspension etc is all uprated but what brakes to fit? I know Chris Witor does a four pot upgrade kit but he was wondering if Stag or Jag XJS brakes would bolt on. And would they be good enough? Any ideas?
Before anyone says it, yes the brakes should have been considered first but he bought the car as is. Goes like stink but I doubt the original brakes would last one lap.

Can't see Stag brakes being much of an upgrade as IIRC the Stag had the same setup as a Triumph 2000/2500 saloon..?Jag may work and would be worth check wheel pcd etc., but I'd guess that if it could be done it would be already being done, and there would be less need for a bespoke 4-pot upgrade kit..?
And if it was getting spanked on a track, I'd invest in a set of AP's TBH.

Your mate ought to be thinking how to keep the discs cool before up grading then he needs to speak to Zeus. They are very helpful. Their 4 pot conversions can be modded to fit any application as the mounting/ bolt hole centres can easily be adapted to suit.The company designed and fitted the London Cab with discs, so that makes your application a doddle.
For track use you really need a vented application here. The 2L wheel arch has no facility to get fresh air circulating so give that alot of thought. Brake fade due to the heat dissaption was a common problem with the Police cars of the day.The old 2/2.5 was the standard car for many forces and used for the advanced driving courses.jith maybe able to help here,with his experience within police workshops.
I trust he is changing the rears , the drums are far too small for track use and I hope he has beefed up the rear suspension mounting points.

I am clutching at straws here but since Jaguar has been mentioned above perhaps it's worth mentioning that old 240 Volvo brakes have been used as a cheap upgrade for early E types and work fine. Now those would be a cheap option from a scrappy I reckon, but only if feasable.
That triggered a few memory cells, as I seem to recall these were the same as the Austin Princess calipers and were 4-pot calipers...?I have heard of Volvo 240 calipers being used on Triumph's in conjunction with 9.5" discs off of a Toyota HiLux of all things.
I've heard the Chris Witor kit uses 10.6" discs off of a Renault of some description, as they fit the Triumph hub with only redrilling reqd., or so I've been told...?
Yep Princess 4 pot callipers are indeed a straight bolt on conversion, fitted em to a rover v8 engined Pi many moons ago and a spacer kit is available from Rally Design so that they can be split and fitted over vented disks... which i cant remember the source of?? i also believe LDV vans still use the same caliper so may still available - but dont quote me!! this may be of some help http://www.rallydesign.co.uk/pdf/designing_4_pot_b...

How about Rover SD1 four piston calipers -available new from Rimmer Brothers, and much cheaper than the Zeus calipers. There are both vented and unvented versions. http://www.rimmerbros.co.uk/Item--i-GRID009014
it depends on what wheels he has,
but have a look at this link,
find the brakes that are as near ,or what ever you want , then fit them ,
I used Peogeot 407 coupe discs at 305 mm and 34 mm thick
had to drill new holes in, and the inner hole needed taken out 1/2 a mm
