Alcon CSL Cup Full Brake Kit

I've got Alcon CSL Cup brakes with RS29s. I got them from a register member, they were virtually on my doorstep at a price that I'd have been an idiot to ignore. They were put on by Darren Woods in Stockport with AP600 fluid.

I have no experience of the APs so I can't compare.

To live with, well they certainly stop the car but it took a day in Wales with Ben for me to fully "get" what they're about. What I'm not sure about is pedal travel and initial feel - initially I was concerned about shunting Ben but as the day progressed, I got used to them and more confident.

Pedal travel is longer than I'd like, and after some discussion with someone on here who clearly knows his stuff - a possible solution was to put on 2lb pre-load valves to retain some brake pressure after the pedal is released.

After some thought, I've decided to leave them as they are, not use valves and just get used to them. The more I drive, the more familiar with them I'm getting and I'm now more able to judge feel and the grab point.

They have a bit of clatter which, oddly perhaps, I quite like.

The general view appears to be that APs are better for track as they have shorter pedal travel and grab sooner (I'm sure AP guys, or anyone that has used both systems will correct and elaborate on that) and the CSL Cups are easier to live with day to day for people like myself who are not out and out track drivers.

I don't see why they should be more expensive than the APs.
