Does anybody know the parts required to complete a S4 brake conversion on an A4?

 

You could always find a junked S4 and just pull the brakes off of that. That would be the easiest way, but then again it probably wouldn't be very easy to find a salvaged S4 now would it?

 

no the S4 has beefeir spindles and so i would have to change those. ill just use my old ones for now and save up for the Stoptech kit.

 

Could you get your hands on the axle and nuckle/brake assembly. That would prob be the easiest route. Maybe have to swap out the brake booster as well. Just my .02.

 

Stoptech make better brakes than audi. i already have a destroyed engine. i need to save money and stoptech is the way to go.

 

I would go with the A8 upgrade over an upgrade to the S4 brakes.
S4 brakes are not even worth thinking about anyway.

I don't even think you can upgrade to S4 brakes on the A4:
1. The master cylinder won't be matched well to the S4 calipers.
2. The part of the car the caliper bolts to is different in the A4 and the S4. Apparently it may be possible to make the S4 brakes fit on the A4, if you swap over that suspension piece as well.

 

I just wanted to multipisaton calipers but ill be getting either the boxter brakes again or the stoptechs

 

Friend of mine has WilWoods' on order right now - front and back.

 

I like the way they look. They scream"race machine"
