Picked up an 08 G37 coupe yesterday. Journey with sport package. Bose/sunroof. No nav.

Axis angle wheels. 245/40 and 275/35/20s. Tein SS coilovers. Aftermarket sway bars (no sticker. Look like stillen) adjustable end links in rear. Stillen gen 3 intakes. Stillen headers. Fast intentions carbon catback (with a magnaflow dual in/out muffler where the x would be??? Very nice Tig welds. The way it's installed and fitted makes me think it was put in when the system was built). Aluminum underdrive crank pulley.

So far I haven't found anything else. Diff bushing isn't blown and I don't think it has a shift kit. Haven't tried looking for a tune yet.

All of the mods were on the car when my buddy bought it a couple years ago. He put in all LED interior lighting and a diode Dynamics turn signal kit.

 

Stillen bars are red and both front and rear adjust. Hotchkis are dark gray and only rear adjusts.

 

Welcome to the site, looks like you found a good one!
