this is always the smartest option when modding the SPI! ;)

seriously though, you'll notice more from a nice suspension and quality tires than you will from everything else combind.

shorty headers are not a good option on any focus! get a race header and weld a high flow cat into the exhaust just after the flex. this will sound better than a shorty and highflow and make more and better power!
the UDP along with the cam and cam gear are good ideas but that is a LOT of work for little gain.

after all that, a chip is pretty much your last option.
FS has done quiet a bit of work with SPI's as has McNews....

wires are a waste unless your current wires are shot, then replace them with basic wires like the FS ones.
a coil is an absolute waste of money, you will see little to no gain in anything from a coil on the focus. you'd get about the same gains as you would from some "typeR-GTR" decals. :rolleyes:

seriously, go with the suspension and tires, you will enjoy the car far more as the engine and tranny will mask mosat of the gains from the poweradders.
