review of ZENDEN strut bars for 2pt engine bay bar, 4pt undertray bar and rear 2pt bar in GRA (Autocross) :
overall i gave it thumbs up for the bars, altou have been using other bars for about a year, so its time to change (thats wat i told myself) try other new things on the market. chasis feels more solid during slalom's and not much understeer (as usual for all FF driven cars) body roll is very minimal with a sense of security that your car wont overturn.
at first i doubted about using alloy as bars as it will crack during hard cornering and sudden hard cornering (as in autocross, u always turn 90deg and sometimes 180deg for roundabouts), but i manage my own findings rather un-true, it is solid in fact more solid then the usual steel... as R3 guys has been using alloy on most of its testing and prototype cars.
