Brakepads

Indeed, hence every de-dion axle car in the 100+ strong race club I compete in runs racey F6Rs / RS-14s in the front and comparatively mild 1144s in the rear. Even with this setup I default to one click forward on brake bias.

I run RS15s in the front (AP4 pot calipers, floating discs) and RS14s in the rear (AP2 pot calipers, solid discs) (w/ AP 13/16" m/c), with the bias set towards the front. The fronts will lock marginally before the rears. On the roads, you need to LFB a tad for a while when setting off and after a long run without using the brakes to get *some* heat into them before you need them though.

My 620R also eats the rears (compared to the fronts). It definitely works them hard. That does seem like very short life for 2 track days. For comparison I did 3 days at Spa last month and that used about 50% of a set of DS3000s.

That's not unusual. Rears wear fast. Fronts last forever. I always carry a spare set of rear pads for this reason. Also, check the rears regularly as they wear unevenly- the inner pads usually wear faster than the outer ones too...

Very slightly off-topic but still relevant I think.. I've noticed that my rear brakes run considerably hotter than the fronts. This probably has an effect on wear rate.

Surely it's the higher rate of wear that is causing the increased heat?

Not in my opinion. I haven't really noticed any increased wear rate on my rears. The higher running temperature is due (in my opinion) to the rubbish single-piston sliding caliper, the fact they're solid discs, and get less airflow than the fronts.
