hi pads are pretty straight forward to fit. if you do a search theres is a guide on here somewhere. i used it and glad i didnt pay someone to do it. as for pads standard are good for day to day use. i asked this question not so long ago and the ds2500 were a popular choice. i've just fitted brembo max discs, carbon lorraine pads and goodridge hoses. did my first track day yesterday and they were awesome. only prob with these pads is they squeal quite bad
