The kit is very easy to install. It took me 1 hour for both wheels. I got the kit from <A HREF="http://www.sportwheels.com/"> Sport Wheels</A>. The kit is very minimalistic. It is composed of only four pieces: 2 Audi A8/S4 rotors and 2 caliper brackets. Everything else stays stock, i.e. calipers, pads, etc. According to my G-Tech pro, my 60-0 distance was reduced by 5.4 ft.</P><br><hr><br><b>Required tools:</b><br><br>17mm Torque wrench.

re: "notice that the kit requires 16" wheels."<p>Thanks for posting such complete directions.<br>Question though; both the S4 and A8 have 17" wheels, so why the requirement for 16" wheels on an A4?<p>Rich<br>'98 2.8Q sport<br>

I paid $755 for the kit, but last time I checked, the price went up to $795. :-( I don't have any plans to slot or drill the rotors yet.

The requirement is 16" or larger. The reason for the requirement is that the regular wheels on 1.8T non-sport is 15". 17" wheels will work just fine.
