At least one of my fronts is badly warped as well, I need to get some cooling.
IMO the way to solve the brake problem is to add cooling and keep things as simple as possible... I'm good on brake cooling now, so I would be surprised if I end up warping another set of rotors...

In addition to replacing warped front rotors, there are three things getting in the way of me effectively braking this car with ABS off...

1) IMO F3R's are not a "pedal feel" kind of pad, they'd prob be good for a driver with ABS that is constantly going into ABS anyways... and they'd prob be good for a driver that is used to a pad like this and running tracks with lots of long, straight, smooth braking zones... I look forward to trying them out in different conditions and providing more input later... I did run them at Chuckwalla last week and I turned the quickest time I have ever run there - although that track is all about high speed transitions and smooth surface / relatively straight braking zones

2) ride height, tire psi, and suspension setup... with ABS off I'm finally beginning to realize how important this element is in braking... dropping 2psi front (relative to rear) and playing around with damper settings made a HUGE difference... I think for guys with a lot of seat time and test/tune time this will come as no surprise... for me, I was amazed how a few clicks on the dampers etc changed braking performance - particular the braking in response to a brake zone bump and the initial bite when first applying brakes...

3) rear compound that is a match for these F3Rs on the front... during hard braking, my front tires were losing traction first, so once I address #2 above, I'm going to also switch to a stiffer rear compound (the ferodos) to see if I can balance out the F3Rs a bit

Hope this helps... I'm sure there are applications where the F3Rs make a lot of sense - and if there's anyone else reading this that has experience with these pads, would welcome more input
