I like to take mine to the track and I spend plenty of time at WOT but I always shift at 6,000 to 6,2000 (2000 S) and I come in if it feels like the car is getting too hot. I have an oil temp gauge going in soon to help me with that (haven't determined what is too high yet though, or a threshold).
The brakes get plenty of use but hopefully not abuse. I am working on that too.
On my 96 Tacoma I just replaced the clutch for the first time at 201,000 and I am still on the OEM.original brakes
