Does an Audi tt have vented discs?

Yes, the Audi TT has vented discs. Vented discs are a type of brake disc that has a series of holes drilled into the surface of the disc. These holes allow air to circulate around the disc, which helps to cool it down. This is important because brake discs can get very hot when they are used, and if they get too hot, they can start to warp or even crack. Vented discs are more expensive than solid discs, but they are also more durable and provide better braking performance.
