S3 8L - Handling doesnt seem as good as i'd expect

Morning all,

So ive had my S3 (2nd one) for a few weeks now.

So far its got/had;
- adjustable coilovers
- rear trailing arm powerflex bushes
- adjustable rear tie bars
- Front wishbone powerflex bushes (Rear)
- New ball joints

Thats all its got handling side of things, I'm getting it tracked today hopefully.

A few questions;

- What is the best set up for 4 wheel allignment.?
i'll hopefully do some track, like to be able to corner quick as apposed to long distance steady speed driving. would like not too much tyre wear though. Its only my weekend car

- The car feels disconnected at the rear, sometimes it feels more solid through corners but if i eed to brake on entry or lift off throttle a bit it becomes pretty unsettled...
My theory is the haldex is doing its job and adjusting amount of power to the rear wheels ?? but mid corner or on entry this feels poor. Maybe i just need to get used to it.?

-Any suggestions for getting a sweet handling set up would be much appreciated as my mates cupra r 225 handles better round corners and teh reason i went s3 is i thought it would tear round bends being temp 4wd

Cheers in advance

I dare say i contemplated a haldex controller and also thought about those horrible rear spring inserts ive seen to reduce spring movement ? :-/
