Audi A5 Mods painting brake Calipers A4/A5 S4/S5 

I’d say 4 to 6 hours if you want lots of coats, including the primer, base and clear. Ideally you’d leave it overnight to cure though

It helps it stick better so yeah it’s basically necessary if you want it to last

His is a non S-Line.

@@user-vv6ns5dw4v How do you know that? Did he say in a previous video?

@@leeroy3023 for the B8.5 A5 models, you can tell by the front and rear bumper whether it is an S-Line or not. The S-Line front bumper looks a little more aggressive and has different fog light styling, and the S-Line rear bumper has a honeycomb looking diffuser by the exhaust. While the non S-Line just has a flat black round looking diffuser

@@user-vv6ns5dw4v Appreciate the follow up - I was just asking because the front lip he linked in his other video (From ECS Tuning) is saying it is for S-Line Models and his valance has quad tips which is either from a S5 bumper or a S-Line or a cut out on a non s line

@@leeroy3023 no problem, yeah I’m pretty sure he somehow makes front lips fit on his non S-Line front bumper. I’m not positive but I think his front lips are usually from eBay, or they are meant for other Audi models and he makes them fit. Also I want to say he’s using the stock A5 bumper with a cut out to fit the quad tips

Nah that’s right
