bluelighttaxidriver Posted March 5, 2018 Report Share Posted March 5, 2018 Hi. Have mated a spitfire mk4 body onto a mk3 gt6 rotoflex rolling chassis, with a canley cv conversion. Thing is, it sits a bit high at the back, presumably due to the stiffer gt6 spring. Do I need a spitfire spring? And if so, is it a straight swap onto the uprights? Or take a leaf off the gt6 spring?Many thanks. Link to comment Share on other sites More sharing options...
Clive Posted March 5, 2018 Report Share Posted March 5, 2018 Fit a lowering block.....Easier than messing about swapping spring leaves etc. But really it needs to settle first, so I would drive it for a while. Don't forget the rear wheel alignment will need checking/altering, easy enough to do accurately at home Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted March 5, 2018 Report Share Posted March 5, 2018 I fitted a lowering block and longer studs from Canleys when the new rear spring on my GT6 Mk3 sat too high. Had to re-thread the new studs as the threads were too short to clamp the GT6 spring. Link to comment Share on other sites More sharing options...
bluelighttaxidriver Posted March 5, 2018 Author Report Share Posted March 5, 2018 Hey thanks. Forgot to say it has a lowering block already. If the concencus isn't to fit a spitfire spring (really didn't want the hassle), will get the alignment done & drive it when it's ready. Thanks again. Great forum as ever..!

Clive Posted March 5, 2018 Report Share Posted March 5, 2018 Also worth mentioning that there is no spitfire rotoflex spring made. And a rotoflex spring is quite different to a non-rotoflex spring in terms of rate. Link to comment Share on other sites More sharing options...
rlubikey Posted March 5, 2018 Report Share Posted March 5, 2018 I think it's probably worth keeping the extra stiffness of the GT6 spring, so don't remove a leaf - or if you do, don't throw it away! Is it possible to do the old trick of inverting one (or more) leaf(s)? This way you keep the overall spring rate - just lower the assembled spring. Of course you'll have to machine the recess for the rubber buttons on the opposite side of the inverted leafs. Cheers, Richard Link to comment Share on other sites More sharing options...
