I'm no expert but can list a few areas worth investigating, subject to how you wish to use your Ace and exploit full potential.
Many Aces and Acecas Left Thames Ditton with various odd permutations of camber, even with differing camber from one side to the other.
Rear suspension really c an wear quickly and requires regular greasing of all,,, ALL grease points every 500 to 1000 miles.
All bushes need regular attention along with checking that the transverse leaf spring is correctly seating / located. sometimes one can release and retorque other times turning through 180 degrees can help.
Springs do loose the shape and proporties.
Hopefully the figures given earlier give you a starting poin t.
The front camber & Caster settings are :-
Caster Angle 5 degrees
Wheel Camber 1 degree to 2 degrees
King Pin Inclination 9 degrees
Wheel Toe in on Rim 1/16th inch
TR6 front anti roll bar kit also improves handling for fast road and track use. Adjustable shockers also help.
For serious track work it's trial and error, single transverse leaf springs different offset wheels etc etc ..... all pending rules and regulations for the race series you may wish to partricipate in..[?]
Hopefully some one with a lot more knowledge than I can elaborate and give you some additional starter points....[
