Another brake thread? Oh hell yes (S197 to 2019?)

Separate thread forthcoming about my AutoX weekend (especially if I can find any pictures), but.....

I smoked the brakes a couple weeks ago at Pueblo Motorsport. Every session I could feel them giving way near the end and they had visible smoke by the last couple of sessions.... So, I now have some ducts that I will be installing this winter. I noticed today at AutoX that they were more noisy than normal, a lot of dragging hissing sound. I don't think they were bad, but didn't feel up to it today, a bit mushy by the hot half of the day. And I have been looking at what upgrade options there are, I found a lot of older threads.

However, I stumbled into a FB post for a full set of "Brembos from a 2019 Mustang GT Performance Pack" for $200. Brembos, calipers, assorted mounting hardware, etc. Most of the threads have older swap packages, does anyone know if 1) 2019 GT Brembos would bolt up to an 2008? 2) If that would actually be an upgrade?

I have already replaced the fluid, have Hawk HP? pads, braided lines. With stock calipers and rotors. So far, I don't go "Holy cow, this thing stops so hard I can't feel my face!" so have started to look for upgrade options.

Just looking for options on additional projects to do over the winter. I fell in love with the car again today and really like the balance between full track day car and competent punch above my weight in AutoX.

Hawk pads carrying any 'HP*' designation are not really intended for track duty. HPS and HPS 5.0 are performance street (emphasis on street here, but either should be OK for autocross with the 5.0 having slightly stronger bite), and while the HP+ may be adequate for track duty for the rear brakes only (perhaps paired with DTC-60 or DTC-70 compounds up front) they aren't serious enough for front brake use on the track. Note that the HP+ friction curve stops at ~750° - 800°.

HP+ might be good all around for autocross or possibly paired with HPS 5.0 rear pads if you can deal with bite that's considerably stronger than typical OEM or either of the HPS compounds.

If you look at the 6 piston Brembo upgrade kits for S550 (M-2300-V), it says it works for 2015-2021. From this you can be pretty sure it'll fit on your car because the brakes are similar enough for one kit to cover all 6 years. If you are buying used calipers, you'll probably want to look at rebuilding them too.

The thing to watch is going to be your wheels- it looks like you have the factory 17s and those definitely do not fit with larger discs and Brembos. Also, like Mad Hatter said, you'll not be able to use the rotors but the other threads have part numbers.
