Front wheels getting hot.

You can also fit 239 gti disks and pads. (Vented)

Check the caliper pistons and the caliper sliders. They can seize. Take the sliders out, clean/polish them up, some copper grease and they should slide nicely.

The heat wont do them any good and the sliders may be cause of the problem.

If the calipers were sticking wouldn't I have trouble spinning the front wheels freely when jacked up?
They spin fine when front of car is jacked up.

I wouldn't bother.

Check the caliper pistons and the caliper sliders. They can seize. Take the sliders out, clean/polish them up, some copper grease and they should slide nicely.

ONLY use the copper grease well away from the disc though!

This is likely - they get rusty which is when the pads stick.  Expect to find uneven wear front/back pads.

Personally I think you're just getting a lot of brake heat, as the 239s are prone to over-heating, because they are SH*T.
