My 03 MT Coupe just crossed over 106k miles, and I'm looking to do some serious work to it. I'm already planning new R1 rotors, Hawk pads, SS brake lines on all 4 corners, new NGK iridium plugs, new O2 sensors, differential oil change, transmission fluid change, coolant flush, and new drive belts. Can anyone think of anything major that I'm missing that would probably wear out after 100k miles?

I commute 30 mins to work every day, but it's almost all highway miles. I was thinking about replacing the clutch, but it's never slipped on me - and I figure it's not worth spending the $$ until it does. Otherwise, I've been really good at keeping up on my oil changes, tires, etc...but I have done very little PM since 60k miles. Overall, the car has been great - I want to make sure I keep it that way.

 

Most failures seem to start around 120k. Thermostat, power steering fluid/system flush.
AC mainteance [vacuum down weigh for leaks, recharge with new oil] the thing is to defer compressor, evap replacement or just wait and spend the $2,000 sooner.

What about rubber bushings, isolators in front and rear suspension?
Listen to all 4 wheel bearings on rack with stethoscope.
Besure to use rubber treatment on the hundreds of items that degrade from ozone exposure, salt, and heat.
Any valve cover leaks into spark well or external drips?
