Hi there I'm new to this club just bought a 2012 and is250 and I'm looking to modify the car from front to back.. I don't know much about cars but I want it to look and sound sick!!; So please any suggestions would be great, I need help for sure don't know where to start thanks here's a pic for reference

 

Pretty easy
Air suspension
Lip kit
Intake
Header
Catback exhaust
Wheels
2011+ led headlights
Jdm window visor
F sport sway bars
Window tints

 

I'd start with intake + exhaust as those are pretty easy to do and will handle the sound department. In terms of looks it'll be purely subjective what you want to do with it and what order you want to do it in but I'd suggest a new set of wheels and tires first before lowering it with springs/coilovers/air etc. I'm not a fan of the 2012 tail lights so I'd probably go for a 3IS style tail light right away.

 

Just drop, wheel and body kits. Don't wait your time and money on any mode I/H/E because the car will still be slow. Have you test drive and IS350 or ISF?

 

Best advice on this thread.

 

350s are not even fast :'c
