Thanks for that Dave.
The car has had a substantial amount of time and money spent on the suspension already. The current set up is -
Front : custom height adjustable coilovers with Koni yellows inserts, 225lbs King springs (have had 3 other sets of springs in the car with varying heights and poundages before settling on these), custom camber plates (engine crossmember has been redrilled to give more camber too) and adjustable castor rods.
Rear : Re-set leaves with the overider spring removed and lowering blocks installed, Koni reds set at the softest setting, custom Caltrac anti-tramp set up (tramp bars removed for track days due to the fact that they increase understeer).
I'm running 14" * 6" alloys with a +20 offset and shagged R rated rubber that needs replacing soon.
I am also considering doing away with the Caltrac all together and installing a half leaf set up as my brother's Fiat works successfully this way.
The car corners beautifully now so the last thing I want to do is increase understeer. This is the reason why I chose not to just get the `off the shelf' Whiteline 22mm bar.
I was very happy with the 120Y bar when I had my A series motor so I may just get the custom bar made in a 20mm diameter.
Thanks again
Matty
