Mine is lowered 1.75 and 1.9.
Mine IS lower than his but also harsher in daily driving. But it is my daily driver and I am ok My wife doesn't like it though.

Get 35 offset and the stance will be more aggressive by having the wheels at the edge of the fenders.

For the front end, there are various replacements, LLtek sells on as part of the R6 kit which I like a lot. It looks like an RS6 front end made for the A6 narrow body, probably $1500 all in though once painted.
You can also get the R6 side sills or get some 4.2 door blades (will have mie installed soon )
Back to the front, Also get a all blacked out grille wiht no audi rings and you'll get a much more aggressive look. I have seen people also paint their lower front side grilles (fog lights) body color. matter of taste.

 

 

the front end above comes shorter reducing the long overhang look of the A6.
(used to ) Require euro front support bars and need new fog light, than pint... hence th ehigh price. Front end itself is about 700-800 bucks

 

This will deff fit a 2000 2.7t because that is exactly what im looking for. any pics of the doorblades? and is there anything to get rid or the curved back end of the 2000 a6?

 

I'm running 19x8.5's on my 4.2 with 10mm spacers. That gives mine a 25mm offset beacause I have the bigger hp2 brake set up. I agree with formulagigi about filling out thegap in the fender. Gives it a wider more aggressivelook. Good luck.

 

Are those 4.2 doorblades possible for the 2000 2.7? or the Rs6 side sills? Im going to go with the 19" with 35 mm offset and lower it 1.5 front and back i think with the eibach pro kit...

 

^ yes, you can get the 4.2/S6 door blades on the 2.7. I bought them, easy install, just a few screws, they fit right on and look just like the ones on the silver A6 in the pic above. Will give your car a much wider aggreessive stance especially when lowered.

For the rear, LLtek has the R6 rear end too to match the front and side sills above. Looks real nice just like an RS6. Check their site.

 

1.5 is nice drop, not too much but definitely enough to notice. It'll look hot with 19's. Now as i said in one of my first post, do shocks too, not just springs. or your stock springs will wear quicker and the car will tend to bounce. It is a little annoying and then you need to pay suspension labor cost again to install new shocks. Save yourself the trouble and $, get shocls now as you get springs.

Also a great handling mod is the Hsport Sway bars! AWESOME!!!!

 

From the picsI have seen I would lower it with 19s as well should look sweet

 

Drew..
