Can anyone confirm the formal Audi designation for our brakes and the option code?

[SteveKen]

For example, HP2 brakes = 1LX

I don't have the car with me, so I can't examine the option code sticker.

I think the option codes might be 1LJ and 1LP. Is this for front and back respectively?

Also does this correspond to the 2FNR 42 AL 18" designation? Thought it would be something like "Brembo"

Am I nuts, or does anyone else know what I'm talking about here? lol.

where can i find this at? is it something to be known or can i look at my car and figure it out for you?

The 1LJ looks correct for the front Brembos. Maybe 1KZ for the rears. Check it out here:
