Vic,
Yes is the easy answer ! Sadly i broke mine during the 1st meeting ,it snapped the welds around the bar itself so im yet to use the full set up . To remove the std aRB which is a limiting factor , you have to use this style of Roll bar to give any handling benefits , the full GpA kit would be prohibitively expensive( alloy hubs , Tca's and comp struts ) but if youre happy to fabricate soem bits yourself you get the benefits of some std bits and some uprated bits , heres a pic of how i did mine onto TAS style rose jointed tca's ...
