[Fot] Toe-in question on TR4

[MadMarx]

Depending on what you need a stronger camber gain might be desirable.
I run 4.5 static camber  and it gains about 2 degree at full bump.

A well thought bump steer correction makes fast driving on the Nordschleife
easy.
The car is always very calm on bumpy corners.
On bump steer the suspension is set to toe out.
On normal ride toe in.

Cheers
Chris

Guys you can buy an 'adjustable' top fulcrum kit, with which you can move
the
top wishbones back to get more negative camber.

Another benefit is that you can adjust out any twists or tweaks in the top
of
the turret. You just bolt this lot up in the correct position and then tag
weld it all on so that it's solid.

TR Enterprises and Revington TR in the UK offer these and it's a better
solution than shortening the top arms IMHO because you leave the 'dynamic'
geometry in the same configuration as designed.

Tony
