if u go for full UR bars,....legal...
but cages, theres kind of grey areas regarding it...some say legal...some say not... depending on type etc etc.....but at the end of the day, if abang J stops u and says no... u can barely do anything unless u really know the law
anyway...in my view....by right... the 6 point cage should be legal...coz if not mistaken its stated somewhere (mebbe JPJ site) that there should not be anything hindering passengers getting in and out of the car... so the normal 6 point bolt ons should be legal as there isnt anything at the door area...
but like i said.. grey areas.. and also depends on the Abang J that stop u..... ive even actually asked a JPJ officer whos also a car enthusiast... even he doesnt know the clear ruling on cages.
