If it isnt the tpms system being out of wack, It could be the cold weather is affecting the tires and thus turning on the warning light.

The car looks great. Might wanna put a nice black leather steering wheel slipcover on the steering wheel.
The thin and hard plastic steering wheel was my biggest grip about mine.

 

More likely Sensor was not hooked when this appereance package rims were installed. And stripes just make sure that dimensions are proper and not what the picture shows. Measure your car and prep for assurance. Nice stang! Congrats

 

well in the last couple weeks I got the dual exhaust put on... i absolutely love it.
also installed fog lights, a spoiler and flat black stripes.

I'm still undecided about the CAI and tuner. the reviews seem to be all over the place. a lot of people say it's the greatest mod ever and it will be like driving a new car and others say that don't get your hopes up because you hardly notice a difference. If i'm spending $600 or more i'd like to see some decent gains.

here is what it looks like so far, got tint ordered so I'll get that on this weekend and window louvers are also on the way, I'll paint those this weekend and i may put them on for 5 minutes and end up hating them and taking them right off... i guess I'll see.

 

Looking good so far, I would've left the spoiler off though

 

Nice to see another alloy gray mustang. But even more so the stripes. I have matte black stripes waiting for warmer weather to be put on.
