so its that time of the year again and my latest service revealed apparently there is not much right with the car. along with a 'noisy' idler pulley, cracked belt and a leaking high pressure power steering hose, it turns out my pads have about 500-1000k's left in them and the rotors are way too thin. so rather than let them charge me 500 buks for it I thought id do it myself and maybe do a bit of an upgrade. my first question is how often to discs need to be changed as the car only has 98,000 on it? I had a look around and it seems everyone uses rda or pbr discs. I had a look on ebay and there are ventilated disc and pad kits as cheap as 120. im guessing these would be the same size as stock though (is it 298mm? for bf). my next set of questions are myth-busting and physics related - the ventilation only helps for cooling yes? and the stock discs are solid? for any upgrade in braking performance I would have to either get larger discs or a stronger caliper? I guess in a nutshell what im after is your opinions, what would you guys do? will a set of say standard size rda rotors and pads make any difference to braking? and are larger rotors a lot more hassle to install, as im guessing youd also have to purchase an adapter to move the calipers or something? the car has the standard 17inch bf wheels like the bionic xr in the forum letterhead thing. also I was planning on installing it myself since you can find everything on the internet these days and I was under the impression that as long as I use the same disc size its a fairly straight forward swap. or am I mistaken? sorry for all the questions guys, any opinions would be appreciated.
