I have high-performance pads and stainless/kevlar brake hoses. The braking difference is very noticeable. As most are aware, too much braking can create excessive front dive on these cars, causing the back end to become unstable, especially in a turn while braking. So there needs to be a balance here, so I upgraded to a 22mm front sway bar from a 230sl that limits the dive. I had a 30mm front sway bar but it was too stiff.
All installed about 15 years ago. I don't recall the sourcing but Gernold installed the brake pads.
