The MTM brake kit is essentially the OEM Audi RS4 8-piston calipers pieced together with some 2pc. discs. I believe the discs are from PFC although I'm not sure who makes the bells/hats.
The Brembo brake kit is a 6-piston Monobloc caliper specifically developed for aftermarket high use (not an OEM caliper used in a different application) specifically engineered for the Audi S5. The piston diameters and disc diameters are selected specifically for that application. Everything is 100% engineered, developed and manufactured by Brembo.
There is a huige difference compared to the OEM S5 brakes...you reduce unsprung and rotational weight, improve pedal feel and modulation, increase heat capacity and temperature management (virtually eliminating fade and all other heat related issues), decrease stopping distances, improved handling, etc...

It would not be an improvement on the RS4 because it is essentially the RS4 brake system with a different brand of discs. I would have to guess that they use the PFC brand discs so they can manufacturer, or request hats/bells that fit the intended application. Another issue is that the RS4 caliper is not the greatest choice for aftermarket/high performance due to very limited pad options.
At this time Brembo does not produce an aftermarket kit for the RS4 due to very few requests and a lack of genuine interest. If there were sufficient interest, we would manufacturer one, and it would undoubtedly offer all of the improvements that I mentioned for the S5 brake kit. Because of Brembo's OEM relationship with Audi, and the amount of R&D and testing that goes into OEM production, we already start out leaps and bounds ahead of any aftermarket manufacturer. It's one of the reasons why we are able to realize such great performance gains in cars that are already equipped with what many would say are phenominal brakes to begin with. (IE: Porsche, Ferrari, BMW, MBZ, Aston Martin, Nissan, etc...)

Top 5 fluids:
(not in any particular order)
Motul RBF 600
Castrol SRF
Brembo EVO 500 (and also the higher end LCF 600)
ATE TYP 200 - Amber (same as ATE Super Blue without the dye)
AP 551
All of the brake fluids above are great and most drivers will never be able to tell a difference with fresh fluid. The key is keeping the fluid fresh. Brake fluid is hygroscopic and absorbs moisture even out of the air.
Once a bottle is open, use it or lose it.
Throw away any open containers regardless of how much is left.
Do not leave the reservoir open any longer than it takes pour in the brake fluid.
Flush the entire brake system regularly. (I flush every 5000 miles or 3 track events)
The higher end fluids do tend to have less compressibility which translates to better pedal feel, but are also more hygroscopic than the others. The higher up the food chain you go (Brembo LCF600 vs. Brembo EVO500) you will need to flush more often. Also, if your vehicle sits for long periods of time without use, you should ignore the idea of judging mileage or track events and flush the sysetem before any big event.
