billyboy Posted August 1, 2015 Report Share Posted August 1, 2015 Hi. Not really a new topic,but my car has had a lower bonnet height on the offside,and reading members comments I decided to check out the anti roll bar.And sue enough I found it was twisted. My car is 1967 with standard springing all round,so therefore as the early roll bar appears to be unobtainable,and I do not intend fitting a swing spring,do you think a new thicker roll bar will be ok. My type of driving would be termed no chances taken!! ha ha. Bill. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 1, 2015 Report Share Posted August 1, 2015 the larger dia bar was used across the range in later life so yes its going to be fine you maywell need a new clamp and certainly bushes to match Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 1, 2015 Report Share Posted August 1, 2015 Canley or most suppliers I reckon sell the same unit , just search a good price fitchetts, rimmer, or any close to home and save on courier costs pete Link to comment Share on other sites More sharing options...
Clive Posted August 1, 2015 Report Share Posted August 1, 2015 As a thought how is the car with no anti roll bar? Does it drive level? Thicker ARB will increase understeer a bit. Worth thinking about as GT6 do that quite well already! Link to comment Share on other sites More sharing options...
68vitesse Posted August 1, 2015 Report Share Posted August 1, 2015 Bought one for my MK1 2L Vitesse and adviced not to use it unless fitting a swing spring to the rear suspension. Regards Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 2, 2015 Report Share Posted August 2, 2015 sure all later mk2 had the thicker bar as std. it was good enough for triumph to upgrade to this . most anti roll problems or understeer are down to incorrect geometry, get the load on the seats( if thats the spec) set the front and rear toe and she will be fine we had a courier spring and the thick bar on my Vit6 saloon and that was on rails with a swinger it was more of a boat !!!

Clive Posted August 2, 2015 Report Share Posted August 2, 2015 Only swing spring cars ever had the thicker ARB, to counteract the lack of roll stiffness at the rear. Couriers had no ARB at all, and handled brilliantly. On my herald estate I ran the courier spring without the front ARB and firm front springs. (440lbs) and that made a nimble car for autotests. GT6's do understeer, way more than the vitesse. Trust me! You want to do all you can to reduce the tendency. Now, the OP drives "My type of driving would be termed no chances taken!! ha ha." but I am unsure how to take that. If he means thrashes the car (a good thing) then he may wish to do some more research on the best way forward. If it is a moderately driven car, he may not notice.....

thescrapman Posted August 2, 2015 Report Share Posted August 2, 2015 Is not a Mk1Gt6 AR|B the same as a Spitfire or Herald or Vitesse one? If not available new, then there must be loads about secondhand. Cheers Colin Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 2, 2015 Report Share Posted August 2, 2015 most sites show 207093 (1/2" bar) as NLA ( good cause they bent) and use across the range 217033 the 7/8" bar so as new only the 7/8 bar is available Pete Link to comment Share on other sites More sharing options...
billyboy Posted August 2, 2015 Author Report Share Posted August 2, 2015 Probably the best definition of my driving is no interest in speed whatever,just driving an old car in its original makeup,and staying safe. Bill. Link to comment Share on other sites More sharing options...
