  1. I have moulds (Oz spelling) for the covers and I have a template for the trims. I had several attempts to make the rounded trims and found it just too difficult but the flat trims are no problem. You can make them either in steel and have them plated or in aluminium (Oz spelling) and polish them.

     

    I've research the trims fairly thoroughly and I don't think there is a 'correct' style. The rounded style is used on most road 250 models and other Ferrari of the period but many of the restored 250 GTOs have the flat style.

    Boy from Oz; are you prepared to sell me a pair of the perspex covers and trim rings and ship to the UK? I should be most grateful if you could.

  2. I have a reasonably rot free 240Z and some Alpha1 panels here in the UK. Part one of the plan follows what many of you have already done in replicating the 250GTO in this way and I thank you all for the help I have found from your past posts. First question:- I believe the proportions of the 250 are better represented if the z is lengthened between the front wheels and the windscreen. I think someone told me it needs to be 3 inches longer. Am I right in thinking one or more of you has done this? Any advice on getting the proportions right would be appreciated because part 2 of the grand plan is to take new moulds from the finished body. Regards John

  3. Although you do not say so it sounds as if the problem is just at the front. Am I right? If so here are some comments that may help.

    If you have increased tyre diameter 3" and are still 2" too low then it sounds as if the car has sunk 3 1/2". This seems an awful lot but is not impossible if the changes have increased weight at the front. If you just reposition the spring base you will still have 2 problems -1 when the car goes over a bump the springs may become coil bound and solid (disasterous handling) -2 The springs are still weak (spring rate) relative to the heavier load they are carrying.

    You need someone who can make new springs. Measure the length of the current springs when under static load. If you then take them to someone with reasonable knowlege or a spring rate tester, he will be able to calculate what is needed in terms of rate and free length, to give a static loaded length 2" longer. You may also need to uprate your dampers to a stiffer setting to control the dynamic movement of the heavier weight
