I use SRF on OEM pads. No issues at VIR for ~30 minutes hauling down from ~150 on the back and ~140 on the front strait. I did install the SS brake deflectors (plastic piece only). Still working on some data but I put them on to limit the tires from giving up 3/4 into a session from heavy repeated braking, friction and excessive pressure rise. My fronts get greasy. I did one cool down lap with the deflectors and the tires seemed to recover rather well. Brakes haven't been an issue for me. Tires...

I do have Spiegler SS lines but I don't believe they do a thing other than "improve" the feel with a stiffer pedal. Lines are more about how you like the pedal to feel.

+1 on SRF. Works fantastic. Plus you only need to bleed the system once a year...
