better brake+tire

After a few months of work, I didn’t have time to take care of my vehicle, I finally have to get to the brakes and need help. Problem: When braking down at high speeds, I have the feeling that the front axle is flying apart. It’s incredible at the front and my box is hard to hold. I have a 9-3 aero01 with hibernating step2, but unfortunately still the original brake system. I want a reliable, well-packed Bre manlagen, which allows constantly fast driving and possibly also a short detour on the ring – my dream is to move the car there times. But only with correct brake, I by chance came across some horror pictures of Philipp’s racing and the empty brake line – so would my serial brake look after the first turn… Can anyone recommend me something? Maybe not exactly extremely expensive? (Two months ago I had an offer here from the Ru I would also be grateful for a tire tip on my Aerofelge 17”… Drive at the time 215/45 ZR17, Dunlop, but what exactly did I forget.
