Front Tyre wear/Camber Angle

[bmcecosse]

Thanks for the update - it's not any way I would have my suspension - but it's your car........... One poly bush (on the outside) of the tie-rod front mount makes a good improvement - and pulls the castor up slightly when tightened right up so the inner rubber bush is compressed.

I'm interested in your comments - what would you do differently? What do you see as the shortcomings of the set up described? I note the bit about half poly, half rubber for the wishbone. What is the advantage of pulling up the castor angle?

Well - I have a little negative camber which makes a big improvement, and NO roll bar, which only induces even more understeer on a Minor (unless balanced with a roll bar on the rear suspension?) .....and I don't use tele dampers....., the heavy oil standard dampers are very effective. Also slightly lowered all round, with bump stops cut down to leave sufficient travel. Otherwise - just the same as yours! Castor angle increase induces more negative camber on lock. Look at any modern car parked on full lock - and notice the neg camber on the 'outside' wheel is very pronounced - this because they have a LOT of castor, and power steering of course to make it all manageable !

You are also inducing a greater steering axis inclination angle (kingpin angle) by shimming out the bottom to give the more negative camber. The greater SAI in fact causes positive camber gain in turn of said outside wheel, hence the need for more caster angle also.
