Corkheader Posted January 23, 2007 Share Posted January 23, 2007 My 1.6 VX classic can get very skitish over 70 on bumpy roads. I have tried experimenting with tyre pressures but it dosnt seem to make much difference The car does not have adjustable dampers and is as far as I know standard, A frame bush is new. Can anyone help me with tracking and castor settings for everyday road use? Thanks John Link to comment Share on other sites More sharing options...
allen Posted January 23, 2007 Share Posted January 23, 2007 You could check the ride height. The rear should be 15mm higher than the front otherwise you can do nasty things to the handling. allen Link to comment Share on other sites More sharing options...
Allen Payne Posted January 23, 2007 Share Posted January 23, 2007 Also check the toe in/out of the front wheels; too much toe out can cause this so try zero toe in/out to start with Edited by - Allen Payne on 23 Jan 2007 20:31:02 Link to comment Share on other sites More sharing options...
Support Team c7trp Posted January 24, 2007 Support Team Share Posted January 24, 2007 I've had this on my 1.8 Roadsport. Problems were: 1: Knackered rear damper. 😳 2: Adjusted tracking to 1 deg or so toe in from 2.5 toe out 3: Adjusted castor from > -2 deg negative -1 The car has been transformed. Caster was hard to adjust as the threads were seized in the top wishbones, so had to buy new wishbone 🙆🏻 Blat mail me if you want a copy of the settings from the build manual Link to comment Share on other sites More sharing options...
Corkheader Posted January 24, 2007 Author Share Posted January 24, 2007 Thanks for the advice - will get the tracking checked. John Link to comment Share on other sites More sharing options...
sjmmarsh Posted January 24, 2007 Share Posted January 24, 2007 Tim I think you mean -1 camber (wheels lean in towards the top of the nosecone), not castor (the angle of the strut in the wheel hub away from the vertical in the F-R direction) Steve Link to comment Share on other sites More sharing options...
Support Team c7trp Posted January 24, 2007 Support Team Share Posted January 24, 2007 Steve, Correct - soz - think the little grey cells are failing 😳 Caster is the next thing to check! Link to comment Share on other sites More sharing options...
Sheds Moderator Posted January 24, 2007 Share Posted January 24, 2007 As posted above the first thing to check is tracking. Slight toe in (say a degree) gives stability, slight toe out gives a faster turn in at the expense of stability. Some racers like this but on the road it's probably hard work. Between the 2 is a compromise. When I got mine I had it flatfloored (under £100) and it was transformed, with everything set up and much more stable handling.

Corkheader Posted January 27, 2007 Author Share Posted January 27, 2007 Thanks for the posts - Not heard of flat flooring, what does it involve? John Link to comment Share on other sites More sharing options...
sjmmarsh Posted January 27, 2007 Share Posted January 27, 2007 John Flat flooring (aka 'corner weighting') aims to get the weight of the car evenly distributed between all four wheels. In practice this is difficult to achieve, but it is possible to get the weights on the two front wheels equal (helps prevent one wheel locking under heavy braking) and the rake of the car from front to rear right (a 7 should be 15mm higher at the back than the front). To do this you need a perfectly flat floor, equal tyre pressures and adjustable dampers. Steve Link to comment Share on other sites More sharing options...
