I am considering the Stoptech stage 1 upgrade for my TT. I have run 4 ACNA driving schools on the stock system and I know I need new fluid (Motul RBF600), but I am thinking on adding the stainless lines and new pads.
Anyone have experience on using any of the following pads on this vehicle for "dual use"?
Ferodo DS 2500
The car spends most time on the street, so I don't see high operating temps until I am on a track. I must admit the stock system worked fine until July at Willow Springs when I think I probably boiled the fluid (98 degree air temp and prob 140 track temp).
I was wondering if anyone had used the Axxis on the track and their experience.
Thanks for the responses!

I wouldn't consider the Pagid Orange a dual use. It's far too aggressive to be useful on the street.
Keep in mind that all of the others will be fairly dusty, some of the dust can even be abrasive.
If you're not the type to clean your wheels regularly (or don't care much for them) I wouldn't particularly recommend any of those pads on the street.
Pagid Blue, Ferodo 2500 are two good choices, as would be the Porterfield R4S, and Carbotech Panther+. Similar caveat with those as well. They'll be relatively noisy and dusty.

Heck the stock pads are so dirty I clean the wheels every week anyway! If I could just find P21S gel in a 55 gallon drum...

I evaporated a new set in one 30 minute session at Mid-Ohio. The pad was 90% gone, and the rotor looked like someone used a brush to paint molten metal onto it.<ul><li><a href="http://forums.audiworld.com/a8/msgs/81590.phtml">10 Pad Comparison</a></li></ul>

Does anyone have experience with the Axxis at a HPDE? FWIW, the stock pads on the car held up fine for 4 driving schools, but maybe I am getting a little faster now.

The comments in the <a href="http://forums.audiworld.com/a8/msgs/81590.phtml">Pad Comparison</a> were for the Axxis Ultimate (PBR makes this pad and calls it the PBR "Ceramic"). In addition, PBR makes the Axxis "Deluxe Plus" and the Axxis "Metal Master", but I don't have any experience to report for these latter two compounds.
The PBR Ceramic was the one pad on the list that I've never used, but several A8 owns are very pleased with it's street performance. One A8 owner (I don't remember who) did report that this pad faded on track.

maybe with the big brakes on the 3.2L and not being as heavy as the S4, S8, etc. it could be the pads will hold up.
Guess I'll be the guinea pig for Axxis Ultimates on the car and driving school. I will post a report in Novemebr after Infineon.

Stoptech put stickers on the pad box "Not for Track Use". Well previously reading that Axxis says it's a combo pad I ignored Stoptech's warning, took a chance and did a track event.
Well StopTech was right those pads overheated and smeared pad material all over the rotors. The TT being a lighter car may have a different outcome but on A4 I would skip them for track use.
