TRD2000
i now have whiteline sways front and rear and if anything it's a tad tail happy.... good for laughs on club runs but it IS more squirmy than with the factory sways.
That's what I found when I fitted Whiteline 20mm ARB's both front and rear.
Refitted the 19mm stock
rear ARB and tail happy problem went away.
A stiffer bar on the front only worked best for me.
