I just purchased a 2001.5 S4 Avant and wanted to know what mods I should do. I'm not trying to spend a ton of money but I got a couple grand to put into it (1-2k) it already has a software upgrade and big brake kit. Please help me out if you have any advice. I'm not a dick who acts like i know everything so Im open to any help/info you might have.

Things I'm looking to do/need info about.
Exhaust
Air intake
Fin
Springs/coil overs?
Blow off valve?
Throttle body spacer?

 

single turbo! lol

 

In all honesty man the first thing I would put my money towards is making sure all the engine maintenance is up to date.

If those engines aren't maintained then they can turn into a money pit faster than you can imagine.
Anyways congrats on the purchase! I love s4 avants, put up some pics!

 

^^^ this.

 

All the maintenace is up to date on it so I'm just looking to do a few things that will set mine part from the rest. It's the dark blue on and I'm taking the 18" s4 rims & the roof rails to get powder coated in gun metal gray. Then I'll be putting up some pics.

 

I like where you're headed already, I would probably put the money towards coilovers, you'll fall in love all over again. Also you said theres a software upgrade, does it have aftermarket diverter valves? If not take a look into them too.

 

Coilovers. Raceland $400 and not bad but not like these $700+ ST coilovers. Its up to you. From what ive heard ST are smazing but to fully use them to there potential youd need frequent adjustments and Racelands are good for street coilovers. You looking to spend this money mostly towards performance or makin it sexy? Chipped s4 already gotta be pretty damn quick. Coilovers, tints, powdercoats, headlights etc imo. But like melo said your gonna wanna make sure your chip has its supporting mods like upgraded diverter valves (dont get a blow off valve).

 

I would go with coilovers and possibly a set of E-Code headlights.

 

Isn't chip and exhaust going into stage 2?

Coilovers are great for adjusting your height to your liking. I only adjusted mine once for winter and decided to just pick a height and stick with it.

 

Stage 2 chip would benefit after exhaust and intake.
