selection of swaybars, for fast street tiers TW180
 

I thought I could post it here too.
want some advice (Toyota GT86.)
I will run the Time Attack Club series for 2015 in Sweden and would like some guidance to begin with,
know that they're completely individual how one prefers to set his car, but thought that perhaps more people have tried different settings here and can recommend what is bad and not :)
Have driven 7 track events 2014, on the following chassis.
BC racing BR coilovers. 10kg front / rear 7kg, oem Toyota GT86 swaybars and 225/45 17" Falken Azenis FK453 TW200.
the car has felt good, and have been really competitive, but on quick sharp turns,I think the car rolls a bit on the chassis.
so now I'd like some help with experience, about how stif sway bars I should have to tw180.
Club regulations allow only tires with a minimum UTQG180 = TW180 like the Yokohama Advan AD08R. do not want to be too hard either,because then I will lose time,because the tires are not sticky enough
so whats the limit of the thickness of solid and hollow sway bars, before they become too stif that they are just for r-tires and slicks fitment.

would appreciate it if people who have tried different thicknesses on swaybars and spring rates on fast street tires.
And actually seen a difference at times could answer

O and for 2015 i will be driving Advan AD08R 245/40 17" on enkei rpf1 17x9 et35.

There is nothing wrong with body roll. If the balance of the car is what you want, leave them alone. Save money for better coil overs if you want to go faster

Are you finding the car very understeery? With such a soft rear end compared to the front (9kg/mm vs 4.5mm/kg at the wheel) I would have thought higher rates at the rear would be more beneficial than upgrading the sways.

okay will check it over.
got these coilovers free :) whit this spring rates.

But what would be a good starting position, regarding the spring rates for track driving whit tw180 tires.
