    Re: Escort Sigma 1600 Race Car

    Another 35g's removed.
    Now need to get me a fresh set of pads to get the alignement right.

    Still need to decide should I mount them infront of the axle or behind it.

      Awesome car - have looked at this from start to finish! If youre really serious about weight distribution, its ideal to mount the calipers at the front of the diff, rather than the back - this way you are attempting to place all the weight between the front and rear wheels..... just my 5 cents worth

        You are right. And at this point it myay not be any more laborious than placing them conventionally to the rear of the axle tubes. I need to make one new braided brake hose though, but I need to make it anyway so I'll take another good look at this.

          The axle is pretty much done Welded on the brackets today so thats it for the
          And as previously stated I welded the bracket in front of the axle. Now the axle is disssembled and waiting for some paint.

              Finally all ready. Again. This time all the issuea sorted with all new gaskets, seals, roll pins, circlips and a gear lever.
              Funny enough there is a difference between the Tran X lever and Quife lever. Levers are similar but the spacers are different I got a better feel with the Ttan X spacer. Plus the Quife one was delivered with the base assembled upside down
              Lever still tilted to the right with both levers. Now I believe it always has been. Propably to be closer to you UK fellars? I simply have no other explanation for it.

                  I'm sooo keeping my fingers crossed too. Luckily I've not sold the Mustang axle so if I go trough this english too soon I can swap back to the tank axle.

                    With the kind of max torque a 1600cc engine has and that this is a race car not rally chances are you will be fine long term, nice work

                      You've probably already written this somewhere but I can't find it, having had a quick look back through.... what is the total weight of the axle, complete, with discs, calipers, diff, shafts etc?

                        Re: Escort Sigma 1600 Race Car

                        The axle without the brakes (discs and calipers) and oil but otherwise complete is 40.5 kg's the discs are 4.6kg's a piece but I have not weighted the calipers. I've been more interrested how much weight has been shed and the claipers are the same as before so have not weighted them. How much do the Wilwood dynalites weight? so 49.8kg's dry + the calipers which are somewhere near 2kgs a piece with pads + I guess this will take 2 litres of oil so I'd say a darn near 56kgs when fully dressed and ready to go

                        Tempted to go English yet?

                        Are you comparing the weights to the new alli pigs head monster axle? And or to a GP4 Atlas?

                          I'm quite confident too. No point going trough all the hassle if theres no future for it. Hoping the redline cyrup will make the life of the tiny CWP a bit easier. And hey if this one can't take it I'll make a smaller engine for it. After all I used an 5,3:1 english with salisbuty lsd and STD shafts for years with the big spec pinto virtually trouble free. The car was 80kg's heavier but back then we werent allowed this sticky tyres.

                                Full dressed "conventional" thick tube axle with vented discs, AP calipers, big shafts, brace, skid etc in the region of 75kgs. Alloy housed tarmac version (thinner tubes, solid discs and a few other tricks) about 55kgs. Utlimate spec with hollow shafts, titanium bits, chromoly tubes etc more like 45kgs but you could build a whole car for the cost of one of these! I'm working on a semi-floating setup, bit like the Quaife big bearing kit, but (properly engineered) which uses a smaller/lighter hub etc...

                                The next big evolution is to make 3rd member axle (like the english where the diff bolts in from the front) but use an Atlas-size cw&p and a fabricated chromoly casing - this will give the best of both worlds - atlas strength but potentially even lighter than an english! Watch this space...
