Dude, it's your fluid mate!
The fluid we use and recommend is the TRW GP600 brake fluid:
TRW GP600 Dot 4 Racing Brake Fluid
Dry - Min 310
Wet - Min 204
That's about the best out there short of Castrol SRF, or GS610. But significantly cheaper than either of them at $59 for a 1L bottle.
For comparison, some other popular brands:
Motul Dot 5.1
270 dry
185 wet
Castrol Response Super Dot 4
286 dry
184 wet
I'll hook you up with a 1L bottle and a set of 780 degree street/track A1RM (Ferodo DS2500 type performance) pads for for $179 shipped. That will solve all your problems!
