The Nurburgring is different from most tracks. There's long periods where the brakes aren't used much which gives them recovery time. The first 5 miles of the lap are harder on the brakes.
Standard discs / pads will not last long. The S5 is a big heavy thing.
Is it a closed track event or a tourist session ?

In terms of swapping pads you need to be extremely careful in checking to make sure that there isnít any real wear on the brake rotors. The way that our brakes work is the pads and rotors both wear at different rates. If there is any wear on the rotors prior to swapping out brake pads, and/or there are any types of grooves or lines in the rotors, you want to make sure that you still have good pad to rotor contact for stopping capabilities before taking the car out on the track after replacing the pads. |
For the brake lines they are usually as follows: metal from MASTER CYLINDER>ABS MODULE, metal from ABS MODULE>BRACKET, then rubber from BRACKET>CALIPER. Steel braided lines shouldnít be an issue (depending where you put them) and is a common upgrade in car modification. The part number for the lines will be below. I would check with the manufacturer to make sure that everything checks out prior to installing the brake lines.
Hereís the breakdown for the front brakes:
6-piston front calipers
Akebono pads and rotors (Edit from MrSkimo - I researched this and found that the OE Manufacturer for the pads is in fact Textar. These brakes were most recently used in the Q7 (4M) according to Textar brakebook.com - 2586101_402)
Size of rotors: 350x34mm
Single piston calipers
Girling pads and rotors
Pads: 8W0698451K These too are Textar pads, used in Q7 and A4 and A4 Allroad
Size of rotors: 330x22mm
MASTER CYLINDER>BRAKE BOOSTER:
8W0614725P (specific to Sportback)
8W0614726P (specific to Sportback)
8W0611775C (rubber flexible brake hoses x2 for rear)
8W0611707D (flexible brake hose for front)
8W0611708D (flexible brake hose for front)
Both the front and rear rotors have a 5x112 bolt pattern and whatever upgraded brakes the client decides to go with will need to use the same. With regards to the compounds I donít know that information and it isnít available to me.
Hiya and have fun. I confirm that track days are very very hard on tyres so one spare set is a good idea yes, maybe you fit them AFTER the event for a safe drive home. Sure you cannot take a set with you but as you say, so what the heck, you must make the most of your time!!! I reckon that over 2 days even at 6 or 7 or 8 tenths you are very likely to ruin a set of tyres.
Yeah I dont think you need to worry cos Michelin are an excellent manufacturer. I think that I would fit Michelin for the track days and then get the new standard ones back on to drive home???? But not really much to worry about either way. Have fun !!!!
