Adrian Saunders Posted September 4, 2019 Report Share Posted September 4, 2019 I have straight radius arms on my Rotoflex mk3 GT6 but the manual shows them as offset. Which should it be? I can’t believe I’ve only just noticed this! Link to comment Share on other sites More sharing options...
Adrian Saunders Posted September 4, 2019 Author Report Share Posted September 4, 2019 Ok. In the supplement of the ‘shop manual, same comm numbers referred to but the straight arm is shown. Is the main section of the manual the wrong way around? Vitesse rods are offset, GT6 are straight? Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 4, 2019 Report Share Posted September 4, 2019 im of a thought GT6 were off set as the chassis bracket is more inboard than a vitesse so the eye's are off set to correct the pivot alignment as they said on the news the I's have it Pete Link to comment Share on other sites More sharing options...
ludwig113 Posted September 4, 2019 Report Share Posted September 4, 2019 as pete says, the mounts are off set and the radius arms are straight. paul Link to comment Share on other sites More sharing options...
Gully Posted September 4, 2019 Report Share Posted September 4, 2019 The radius arms on mine are straight, but then they don't match any in the manual or parts catalogue! They fit directly into the brackets without hint of a need for an offset. Mine don't have the turn buckle arrangement; the rear section simply screws into the front. Means to adjust you have to disconnect one end, then reconnect, check etc until the rear toe is correct. The parts manual seems to show straight arms for the GT6, although front and rear are different part numbers presumably for threading.

Adrian Saunders Posted September 5, 2019 Author Report Share Posted September 5, 2019 Can anyone confirm the fitted lengths of their radius arms, GT6 and Vitesse. This should help somewhat. Photos would be good too. Thanks. Link to comment Share on other sites More sharing options...

Peter Truman Posted September 6, 2019 Report Share Posted September 6, 2019 See attached photo of a Vitesse Mk2 publicity shot showing the rear suspension, the radius arms appear straight with mounting brackets offset, so I assume that means the GT6 are offset. Hope this helps, its too wet & cold tonight to go into the garage, grovel down & check! Peter T Link to comment Share on other sites More sharing options...
Adrian Saunders Posted September 6, 2019 Author Report Share Posted September 6, 2019 I know that the geometry isn’t perfect but, the upright needs to toe-out to get the bolt in and the bracket is already not parallel to the radius arm end Link to comment Share on other sites More sharing options...
Colin Lindsay Posted September 7, 2019 Report Share Posted September 7, 2019 Going by this shot (Thanks Rimmers!) the arms are straight and the brackets angled, with no angled or offset mounts on the radius arms either. Link to comment Share on other sites More sharing options...
johny Posted September 7, 2019 Report Share Posted September 7, 2019 Adrian, while we're waiting for some radius arm measurements can you measure yours set up roughly as the manual indicates? I wonder if theres not an error in the manual (not the first time) and the angled one is actually for the Mk2 Vitesse..... Link to comment Share on other sites More sharing options...
Ian Cooper Posted March 26, 2020 Report Share Posted March 26, 2020 Hi. Did this ever get resolved? I'm putting my GT6 Mkll back together, which had bent adjusters so I'm replacing them, but the dimension in the workshop manual (424.4mm) would make reassembly impossible, and my radius arms are not offset either?? The vitesse dimensions (373.6mm) appear to be much more likely, would they be correct??? Ian Link to comment Share on other sites More sharing options...
Steve P Posted March 26, 2020 Report Share Posted March 26, 2020 Don`t know about MK 2 Vitesse,i have a MK 1 Vit that i converted to CV which meant using the Rotoflex wishbones and tie rods,the Roto ones are straight and adjustable (the non roto ones are not straight or adjustable)and i had to drill the outrigger more inboard of the original and bolt the mount bracket to get the correct offset for the bars. I have a set of tie bars in my shed intended for my Herald that i could measure,i have no idea what car they came off though. Steve Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 26, 2020 Report Share Posted March 26, 2020 dont forget if left in a hanging position thye wont align until up in a running height Pete Link to comment Share on other sites More sharing options...
NonMember Posted March 26, 2020 Report Share Posted March 26, 2020 The Spitfire ones are definitely shorter than Herald ones, so I'd expect Mk2 GT6 ones to be shorter than Mk2 Vitesse. Indeed, my copy of the WSM gives 373.6mm for the GT6 and 424.4mm for the Vitesse. It does show the Vitesse ones are square ended and the GT6 as angled, though.

Steve P Posted March 28, 2020 Report Share Posted March 28, 2020 This is what i have for the CV conversion of my Herald,it is 460mm end to end.Also looking at it closer i can see the ends are slightly offset. Steve Link to comment Share on other sites More sharing options...
Ian Cooper Posted April 3, 2020 Report Share Posted April 3, 2020 If it's any help to anyone I have just reinstalled the adjustable radius arms, with new adjusters, on my Mk11 GT6 and they are set at 373.6. There is absolutely no way the wsm dimension of 424.4 could have worked and my radius arms are straight. Ian 1 Link to comment Share on other sites More sharing options...
NonMember Posted April 3, 2020 Report Share Posted April 3, 2020 As I said above, my copy of the WSM does not give the long value for a GT6, it gives the 373.6mm figure. The one in Adrian's photo (which may be a later version) has the dimension cells in that table swapped, which has to be a misprint. Link to comment Share on other sites More sharing options...
