Barry, I am curious why you recommend using a swing-spring with the rotoflex type suspension. This seems to me to be a juxtaposing methodology. The Spring that comes with a rotoflex is much stiffer than the swing-spring and does not allow the car to have as much body roll as with the swing-spring.
Please explain.

This would be almost identical to the setup that I have on my Spitfire, which is a MK2 GT6 rotoflex, with TR6 sliding type axles, and heavy duty SWING SPRING. You would not want to use a camber compensator on this type of suspension (not sure if it would even fit with the lower wishbones anyway). The axle length is actually in between that of the early Spitfires (MK1-3, and that of the later 1500) The early Spitfires and MK1 GT6 had a rear track of 48 inches, the GT6 rotoflex had a rear track of 49 inches, and the Spitfire 1500 and late GT6 (Swing Spring) had a track length of 50 inches. If in fact you have sliding (rotoflex) type suspension like mine the best thing to use if you leave in the sliding type axles is a swing spring for a GT6 as well. The sliding axles MUST have the lower wishbones to retain the hub uprights in place. As a foot note, all rear springs, fixed, Swing, early, late, etc that fit the Spitfire/GT6 range, no matter what year, type, or rate, are the same length. There are no long or short springs. There are different rate springs, and contrary to popular belief, the spring rate is actually softer in the GT6 (for the boulevard ride that Triumph was trying to achieve) there wasn't that much weight difference in the weight over the rear axles from the Spitfire, the weight was mostly that big six up over the front axle - There are however long or short axles - So the short answer is that if you want to use a camber compensator on this car - you will have to replace the axles and uprights with early Spitfire/GT6 uprights and solid axles with a fixed spring- And of course you all know how I feel about that :-) Barry Schwartz La Mesa, CA (San Diego) _______________________________________________ _______________________________________________ Support Team.Net http://www.team.net/donate.html [email protected] http://autox.team.net/mailman/listinfo/spitfires http://www.team.net/archive
