  Micheal,
  
  Willwood do two calipers - the Dynalite II, and the Billet Dynalite. The first is slightly cheaper and the second is stronger.
  
  The Dynalite II is prone to flexing under heavy breaking - some drivers say that gives it 'feel'. But the Billet does this too (but less).
  
  Last time I looked the Dynalite was about &163;90 per caliper and the Billet about &194;&163;120. But you will need a fitting kit to go with it - and the whole set for this usually costs in the order of &163;500 - &194;&163;600 if you shop around.
  
  Princess four pots will also need a fitting kit for the GT6 upright but in all honesty you will be VERY VERY lucky to find a set you can use. I tried for over a year to find a decent set and instead opted for a set of GT6 (spaced) for the Capri vented disk. Also, the princess calipers are a real bugger to bleed - dynalites not so.
  
  Try 'googling' Dynalite II and see what you can find.

    Has anyone used the Canley spaced caliper kit? It looks good value for money and should work. http://www.canleyclassics.com/newproducts.asp?uid=... any comments??
    
    There was a rumour going round a while back that the Princess owners club were banning the sale of their recon calipers to non-wedge owners, because everyone was robbing their cars for the 4 pots - having said that, everyone I've ever spoken to who's ever had a set on a car said they were not that much better than the standard set-up.

        I fitted AP 4-pots, and Capri vented discs, to my old race Vitesse. Changed bowel-emptying fade from smoking standard calipers to total lack of fade and a shorter braking distance than (some) Spitfires. But that amount of heat input is unlikely on the road, so 4-pots alone may be of benefit, but I'd go for whole kit.

      I have princess 4pots on Spitty uprights, the only fitting kit needed was a 2-3mm spacer (washer) under each mounting lug. I have found them to be extremly effective.
      
      They are pretty heavy but have no discernable 'flex' that some of the less expensive aluminium calipers may have.
      
      I think a lot of thought needs to go into what pads you fit too. The best calipers in the world are only as good as the pad material and conversly a standard setup can be improved by fitting better pads. It depends on your driving style and what you want the brakes to do. ie my race car uses mintex M1155 pads which are useless when cold but after 2 laps will stop the Ark Royal.
      
      Cheers

    Nig,
    
    I think you'll find that Rally Design do kits for Triumphs for around &163;350 - somewhat less than the &194;&163;500 you quote.
