Yes they ALL have anti roll bars front and rear, when you see discussions on here about fitting ARB's it's referring to aftermarket stiffer ones... ie TRD,Cusco,TTE
Strut bars are mostly bling as regular road users wouldn't notice any effect, on a track though where the rest of the suspension is already uprated then they may have some use...
prolex uk sell uprated ARB's for a competitive price and lots of other bits and bobs ;)
good luck
