To improve handling on track days you need to do a lot of things.
Front:
- front coilovers with 60kg spring, springs can be done aftermarket
- front lower and upper strut bar
- bigger anti rollbar from Trofeo or let someone to make it for you
Rear:
- rear suspension can be ast it is as you already installed the coilovers
- rear torsion bar as it was used on Trofeos Grupo A (as far as I know it will alsofit from a Peugeot 205 GTI)
Tyers:
- Slicks (I use 160/530 R13 dimension it fits on a standard sporting wheel you only need to remove wheel arches) the scrub only in a realy reayl thigt corners. This dimension is or was used in Formula Renault 2.0 for front tyres.
Bushes:
- powerflex or strongflex bushes or something simmilar allround
Just out of curiousity, what ARE tour current tires? As long as you do not have traction problems (as in: problems to get the power on the track out of corners), I do not think bodyroll is your biggest concern, but should try good tires first.
Good tyres won't solve the body roll problem and grip from my own experience.
I have changed all the bushes with strongflex sport ones also the engine and transmission mounts. We refurbished the shock absorbers 20% more stiffer than the original ones with bilstein inserts and eibach prokit springs. Front lower and upper strut bar plus OMP roll bar. And also when I am using slicks I still have body roll problem.

cheapo budget ones. I havnt got the money at the moment to buy really expensive tires for the 2 times a year I go on trackdays
my body roll is similar to the pic above, probably not quite as bad as that. I managed to get the rear wheel off the ground a couple of times I was told. so with better tires I should get better grip and increased body roll.
I just want to improve things to a point where it is fun and isn't sliding all over the place, but doesn't break the bank either.
