abs is xli(Y).it wud hav the best brakes if abs is installed in an xli.
well my frnd has a 07 xli,one we went to toyota dealers to ask them if they can fit an altis abs system in his xli.but they knew SHIT about it.their reply was "yar vo altis hy ye xli hy oski brakes is mai kaisy lg skti hain?"
i felt like kicking his A**.i m also 100% sure it can b done but its very difficult nd migh cost u more then 50k(that wat that guy told me,dnt know on wat basis).
but u can put the abs brakes of the corolla X,which is the imported corolla.a guy on pakwheels did it n the results were positive.
just search a topic like urs in my profile nd read it all.
