2002 Ford Mustang GT - Daily (in the Summer)
Pretty much all the regular bolt-ons: K&N CAI, Steeda Underdrive pulley kit, Steeda adjustable timing pulley, C&L MAF sensor, Magnaflow catback, Steeda Short throw shifter w/Bullitt shift knob. About 100k miles on stock plugs, brakes, and clutch. It's in the shop right now, I kinda ran out of road at about 60 MPH. Not totally sure what happened but I went ~100 feet off the road, launched it off the road, and landed in a small pond

I'm still pretty pissed at what happened, but the car is fixable so it's all good. Oh yeah, I'm OK too.
1997 Mazda Protege - Daily
Old pic (I ditched those stupid hubcaps and got alloys), but the best I've got. KYB GR-2 struts, HD clutch and pressure plate, Bosch cap rotor and wires, NGK Iridium IX plugs, and K&N filter (not cold air, just one of the ones that fits in the stock box). Totally gutless and despite the big improvement in handling by going to the KYB struts it still doesn't handle nearly as well as the Mustang, but 40+ MPG in the Summer and it gets me anywhere I need to go.
EDIT: Didn't mention any races. The Mazda is the one I've driven the hardest, been pretty easy on the Mustang (until I sank it, of course). I took some idiot in a V6 Hyundai Sonata from a dig, that was funny. I kept up with a Dirtymax Chevy truck, smoked my friend's Mercedes 300D and his Subaru Forester, took out another friend's V6 Toyota Rav4, and I've toyed with people with it. If I had an automatic it would be horrifically slow, if it weren't so light it wouldn't do as well as it does now. I have had it faster than the Mustang, as well. The governor on the Mustang kicks in at 135 and the Mazda hits the fuel cut (nearly 7,000 RPM) at about 150 in 5th gear. The only thing I've raced in the Mustang has been a Nissan 240SX. I walked away from him from a dig, 20 roll, 40 roll, and he didn't stand a chance against me when we did a 60 roll. It's got the stock rear gears (3.07:1, I believe) which means it doesn't really accelerate too well but it has plenty of torque. I want to go to 3.73s but cruising at 90 MPH at 2,000 RPM is so nice.
