Finally got round to changing the rears on the RS3 the other week.
The fronts were changed to MPS4S a year or so ago, but the rears were still on some Pirelli’s.
Whilst they still had 4/5mm left on them they were old and had started to crack a little.
Now the car never felt like it was a great handler, and I wouldn’t really expect it to be as it’s a bit weighty at the front and is more of a brute force and ignorance type thing.
But since changing the rears to MPS4S as well the difference is night and day. I wouldn’t say I usually notice a huge difference when changing tyres but it feels so much better now.
The car feels a lot more planted, less twitchy, and definitely feel it when pushing tighter corners/roundabouts. The rear always used to feel a bit sloppy, which made the whole thing feel a little wobbly/slidey, but now it just feels solid.
And they ended up costing around £135 a corner fitted, which for 19s seems very reasonable.
