Still notably slower than the M2 though

They wrote:

  • that the damper setting was not stiff enough for a track setup,
  • difficult to handle on the limit
    • still a bit the haldex problem under power but what is new: when you lift of the gas pedal you can generate an unpleasant overstear reaction
    • Pirelli P Zero R02 had inferior grip
    • Brakes: even the ceramic discs fail on tracktest

all together you can not really capitalize on the power advantage

So what should be done IMHO is a serious brakes cooling (than you could stay with steel brakes?! -5000Euro), optional semislick (about 1000 Euro Nankang AR1?), optional superlight wheels (open end), optional trackday chassis setting (about 2-3000 Euro).
-> together about -4s on the Sachsenring?!

your suggestions don't really help with the balance issue though

If you understand balance as mid corner balance between under- and oversteer sure you can modify with spring rates and camber, tyre pressure, anti roll bar. It's not only a question of weight balance which is actual 58/42 % for the RS3 which is better than the old model (thanks to the lighter engine)

The haldex system will still create understeer. And the car will always create power-understeer.

This car is really two-faced. The engine is marvelous while the chassis, suspension, breaks and tyres are just mediocre.

I dont want to excuse the issues of Audi, just wondering if it could be optimised aftermarket. Given the fact that great FWD cars have a good handling on track (Megane RS Trophy , Golf Clubsport S or Civic) this should be achievable with a non Perfect hang on AWD I suppose.

But sure Audi should have taken the AWD of the RS 5 or similar for this RS3

1:40? Damn that's barely faster than the 335hp RS3 from a couple centuries ago, and slower than a Audi TT-S which has some 90hp less?

Added Hatch

It lost comparison against BMW M2 on Sachsenring:
M2: 1.37.77
RS 3 1.40.01

BTW: Peak Power and Torque is not on 1 RPM with modern engines:
Max. 294 kW (400 PS) 5850-7000 min -1
Max. NM 480/1700 - 5850 Nm min -1
