How can heavy calipers be beneficial ? I have heard that alloy calipers would save around 36 lbs !! But again I have to prove that alloy calipers have been used in period if I want them FIA homologated. Not easy !
Few picture of the post race parc ferme packed with touring cars.
OK.. My prejudice comes from the fact that I've always considered 'mass' to be GOOD in braking, but that comes predominantly from lighter weight rotors warping. I've never had one of the 60's corvette rotors to warp! but you are talking 'calipers'...
I just went and weighed one of prepped front Corvette calipers (same as JL8 I think) and got a bit over 10 lbs. So to save 36 lbs with lighter weight calipers, your 'lightweight' calipers would have to be on the order of 1-2 lbs each. Is that what the girling calipers weigh? Do they provide similar piston area of force on equivalent area pads as do the 4 piston calipers you are using now? Is it allowed to grind off the corners and excess metal areas to reduce the weight? or to machine for larger pistons (and thinner sleeves?) which would also reduce weight of the calipers.
PS. A rather extreme solution would be to have the Corvette caliper halves cast in aluminum, then some machining (and cast blast paint?)
.. and SS sleeves and aluminum pistons and you'd greatly reduce the weight, but I think they would still weigh more than 2 lbs??
