what is the difference??? i keep reading usp front and then people are asking if the side blades are usp or s4....and then the rear usp/s4 refered to....

some one please explain this.

 

USP is an A4 with the 'ultra-sport' package...this is what I have....basicallt the only difference is that it has different front a rear bumbers, that make it have a sportier look, door blades (same as the s4 door blades), a rear spoiler, 18" rims stock (not the same as the s4 rims), and usually a 6spd manual instad of 5.

Here is a pic of my usp...basically looks like an s4 but without the twin turbo, but the bumpers are not the same as the s4 either (i like these bumbers best)

 

ok ya thats the front end that i love.

now does the usp and/or the s4 bottom fit directly onto the the a4 top half?

 

I know a standard a4 does need some modification in order to fit the usp bumpers on it, but i have no idea about fitment of s4 to a4 or usp to s4. check audizine.com i have seen some write ups about this

 

so i did more research on the other websites...usp fits with some modification but not alot, s4 will go right no as its a whole bumper not just a valiance.....

thanks for the help guys.
