Hi, I'm looking for some advice on brake callipers. I'm in the process of building a Ginetta G15 for Historic events in UK and continental Europe, specifically long hillclimb events (usually many km in length) The G15 currently has Girling 14LF fronts on the usual triumph uprights, with Lockheed/AP LD20s on the rear with modified Davrian/Imp trailing arms. These brakes are perfectly powerful enough on this car weighing around 530kg or less, but they're pretty heavy callipers, so I'm looking for lighter options. I'll have to keep them iron to stay in the historic class, so-ICP? Can these be run on a car that's road legal/registered and that's going to do a few thousand miles a year. I know they lack dust seals etc but that's not a concern as the car's going to be checked over between events. Are the ICP suitable for some road use? Advice from those running ICPs gratefully received.
Thanks
S
