how much toe out have you got?you could set it to 0 deg and see if that helps,and if im right a harder spring will work the tyre harder so you could soften the front

am i right in saying that to reduce the amount the car rolls i would lower the links in the middle and the outer? trying to keep them as level as possible in the front and im not sure with the rear?

Lowering the link but keeping it at the same angle will lower your roll center and increase body roll.

I have .5 toe out

Everything is stock but the -75 roll centers I changed and i liked how much steering it gave the car . Just started to push really bad near the end of the race..

Guess I can put the 0.00 roll centers bk on just dont wanna loose steering ..

You could try some .4mm under the -.75 blocks and see if that gives you the a compromise.

Correct if its the wishbone, if its the upper link lowering it evenly inner and outer it actually highers the roll centre so less roll

its regarding how much roll the car has,to reduce roll you remove the shims from the camber links,less roll in my case allowed the car to roll through the turn faster

Closest to XRAY 2.9, but they feel very different on the track.

.4mm, not 4mm. See page 12 of the T4 manual (optional fine tuning).
