HEL or Goodridge braded lines & Carbone Lorraine or EBC sintered HH pads are what you're after.
I've HEL's on the front & they are a massive improvment on the stock ones, I keep the rear rubber to reduce the chances of a rear lock up.
Kevlar brake pads aren't as strong as sintered, & i think the stock pads are sintered, so you dont want kevlar (organic)
