bibblebob Posted September 30, 2007 Share Posted September 30, 2007 I have just changed my wheels from 17" to 18" the car was already lowered 35mm but since the change i get a big vibe through the car when i hit about 90mph onwards it only does it with these wheels. They are Ultralite GT2's and are brand new inc tyres and have tryed two sets and get the same problem. Is it possible i need to get the tracking and camber/caster adjusted because of the change in height and wheel size. help Quote Link to comment Share on other sites More sharing options...
merckx Posted September 30, 2007 Share Posted September 30, 2007 I can only think they haven't been balanced correctly. Quote Link to comment Share on other sites More sharing options...

Jake Posted September 30, 2007 Share Posted September 30, 2007 Do the wheels have the correct centre bore for the Supra hubs? If not, are you using hub centric rings? Of the right size? - - - Edit : GRRRR! Scot beat me to it. Quote Link to comment Share on other sites More sharing options...

Maybe balance, but probably lack of concentricity, or the the wheels themselves aren't round. Cheap wheels can be anything BUT round, believe it or not.

bibblebob Posted October 3, 2007 Author Share Posted October 3, 2007 :(Thanks for the advice guys but i think it my be the fact that it has cheap fulrun tyres they are balanced perfect and they do have the spigot rings fitted. But it has gone from standard to 18" with 265x35x18 and a 40mm drop(not 35mm) it must need some camber adjustment. Quote Link to comment Share on other sites More sharing options...

Im curious as I have the same sized wheels and same branded (might as well be unbranded) tyres and I get a vibration around that sort of speed sometimes!
