have had dba drilled and slotted on mine since about 2 weeks after i bought it about a year ago
honestly cant rave about them enough havent found any fade from them so far during "spirited" weekend drives although have yet to head to wakefield or anything to give them a decent thrashing
but most importantly i think if you have a $1000 dollar or more excess on your insurance. it doesnt take long for improvements to your braking system to pay for themself. and living and driving daily in sydney im reasonably sure mine have paid for themselves atleast 2 or 3 times so far

as always tho if your thinking about it. unless your completely 110% sure you know what your doing, pay some one to work on your brakes
