front you have a arb fitted.
like said above, fit strut braces first, they will help you more for what you are looking after.
if you afterward want to fit an arb, keep in mind that if you stiffen the rear up, it will trow the back out more easily and create oversteer.
i still have to do the upgrade myself and i think i would go for whiteline.
22mm at the front and maybe a 20mm or smaller at the back.
but have to find out myself what is or what issn't a good set up.
+ personal choise is something else
