Steve AKA vitessesteve Posted May 20, 2012 Share Posted May 20, 2012 Vented Capri disc will fit into 13 wheels. (minilite replica) Getting the steering arms to fit without them touching the disc was the challenge. Look how close the joint is. Link to comment Share on other sites More sharing options...
JohnD Posted May 20, 2012 Share Posted May 20, 2012 Agree about Capri discs.You will be pleasantly surprised. After regularly boiling the brakes on my Old Blue race Vitesse, the venteds removed fade for ever, and I'm the last of the late brakers.But the ball joint may need regular replacement. It is so close to the disc that the rubber boot gets cooked, and cracks. Spacers between steering arm and upright may help, but there is very little room. A fabricated steel arm, bent inwards might be better, but I've never done that. Do NOT try heating and bending the OE cast iron arm!Austin Princess 4-pot calipers will fit too, if you can fnd them. Modern substitutes will be easier to find, and not need rebuilding, and maybe not need a spacer to clear the thick vented disc.John Link to comment Share on other sites More sharing options...
JohnD Posted May 20, 2012 Share Posted May 20, 2012 I can vouch for the reliability of the Quaife unit.I took Silverback to CLM 2006. While there, and unbeknownst to me, the keyway in one drive shaft broke. As a result, I was driving only one wheel at the back through the Quaife, as the drive shaft was turning in the other wheel hub. This led to less and less power getting to the remaining wheel as the diff. heated up, and I had to stop about halfway back to the Channel.When the car was eventually brought back and the cause worked out, I assumed that the LSD would be knackered, and sent it to Quaife for inspection and quote for repair. It was a very pleasant surprise to be charged a minimal sum for dismantling, inspection and rebuild but astonishing to be told that there was no measurable wear on any of the Quaife parts.Also a commendation for Quaife's (the company's) integrity!John Link to comment Share on other sites More sharing options...
Freebird Posted May 20, 2012 Share Posted May 20, 2012 A shot of my setup with 3.0mm spacers 'tween steering arm and upright and 5.5mm 'tween caliper and mount. Worked for me, but others (Clive) needed thicker spacers at the steering arm. All down to the geometry of the bits on the car. Link to comment Share on other sites More sharing options...
piman Posted May 20, 2012 Share Posted May 20, 2012 Hello John, fitting modified arms, spacers or bending the steel original arms (they are not cast iron but a steel forging) will upset the ackerman angle and affect the toe with lock, probably OK for a racing car but not so good for the road.Alec Link to comment Share on other sites More sharing options...
Clive Posted May 20, 2012 Share Posted May 20, 2012 Read a bit in the TSSC mag where Hugh Glossip wrote an article about vented discs and stuff. He mentioned original TRE's being larger than modern ones. Indeed, this seems to be the case. However, a couple of mm off the back of the hub is a true belt and braces solution :) Link to comment Share on other sites More sharing options...
Alex Posted May 20, 2012 Share Posted May 20, 2012 Maybe I'm missing something here......all Capri's except the last of the line 280 brooklands had 13" wheels anyway,the 280 had seven spokes similar to the 2.8i special but in 15" not 13".If I've missed the point ignore me.CheersAlex Link to comment Share on other sites More sharing options...
JohnD Posted May 20, 2012 Share Posted May 20, 2012 Piman,Steel, schmeel, don't mess with temper by red heat, unless you really know what you ars doing, and I don't pretend to.Ackermann, schmackermann, play with the toe-in to optimise turning angle.John Link to comment Share on other sites More sharing options...
Bradley1500 Posted May 20, 2012 Author Share Posted May 20, 2012 Glen,I was only joking, I like to see any classics on the road. There are quite a few Morris Minors that go to shows around my area, most are fantastically restored and have mirrors under them to see how clean they are. I don't like the car and wouldn't have one but just love to see them on the road and in that condition. :)Clive,You'll have to let me know how you get on and what you decide on doing. I suspect your Zetec Spit will be pretty quick so if the brakes are good enough for that I think they'll be good enough for me.Steve,Thanks for the picture, all quite tight in there.John,It seems the Capri discs are a well trodden path, thinking this will probably be the best route. It's good to hear another opinion on the Quaifie diff, although it's expensive it sounds a great piece of kit and defiantly well built from your story.Bradley.

Mind you I guess this is balanced out by not having to cough up for recon diffs all the time.What would the gearing be like with a 3.63, type 9 and 2500?Bradley.BradleyThe gearing will be rubbish with the type 9 and a 3.63:1 diff. I know this because i had that setup. With the 3.27 I can cruise at 90mph doing 4000rpm with a top end of about 120mph. The 3.27 did affect the acceleration a little but that just means you need more power!!! Now I have EFI I don't find the acceleration too bad at all.

Now that I see those figures the type 9 does not have much of an overdrive. A 3.27 with an overdrive will pull 25 mph per 1000 rpm. Mine on 3.63 with a higher 28 % OD and larger tyres 205/55/15 pulls 24mph per 1000. @ 5800 rpm ( shift light setting ) is 0.8 mph shy of 140 mph. 96 mph at 4000 rpm.
