I've yet to see an aftermarket "performance" cap and rotor which are actually what they advertise. Toyota's the most robust you're going to find... aftermarket makes are usually suspect to me. There are a LOT of people running high output, capacitive ignition systems on stock Toyota rotors and caps. YES, it's lifetime will be reduced, but you're not likely to cut it in half..... unless you've got something truly amazing planned...
Seriously though, if you're pushing enough current to destroy rotors and caps that quick you're wasting time and money... the STOCK ignition is solid enough to run most mods with no misses or partial burns. People put down over 400HP on turbo'd 4 cylinders running stock Toyota ignition systems.
What are you doing that requires so much more?
