Good tyres help, along with the rest of the set-up, but it's honestly not as bad as it sounds on paper. I was a little mortified when I found out they didn't do a rear, but it works well with their coil-overs (and all the rest...)

I guess it depends on what you are comparing it to...to me...that isn't a nice set up.
The S3 really needs a bigger rear ARB than front...and they both need to be bigger than standard...

Running a lower front and higher rear pressure should give you an understeery set-up? As will an uprated front ARB.

Uprated front ARB gives understeer. That's it....FWD, 4WD or RWD...the results are the same...less turn in, more understeer.
The opposite with a big rear...tends towards oversteer. On RWD it oversteers...on 4wd it tends to neutral...on RWD it oversteers.
As for tyre pressures...lower front = deflects more and grips better = better turn in (within limits of course)
High rear pressures reduce rear grip...assisting turn in...makes it want to turn in easier...= less understeer....on FWD and 4WD.
I have never ever got more understeer by running the front pressures slightly lower and the rears significantly higher...on any car I've ever set up....including the S3.

34psi all round does quite nicely, and there's only really turn-in issues if you do silly stuff into round-abouts. Otherwise it's very neutral.

Ahh....but to someone with a penchant for doing silly things on roundabouts, I want the extra turn in you get with higher rear pressures.

Looking forward to it, just a little unsure of mixing an Eibach ARB and a Neuspeed one. Hopefully, it'll be all good.

There are no issues with mixing different makes of ARB...as long as they are quality makes.
It's the simple spring action of the bar in relation to it's size and make-up give linear results regardless of who makes them...you'll be fine.
...and you'll love the feel with the big rear ARB.
