Suspension and Drivetrain Advice Required Please

Matt,

it's your own decision to choose the right parts. Nobody else will know what's best for
you. Driving, steering, ride comfort - all a question of personal taste.

Coilover B14 or just B12? I don't know what's right for you but I'd go für the B14 then.

ARBs? I've chosen the 28/24 mm H&R, but if TÜV wouldn't be a problem I would have
done it like Rex did (26 + 24 mm) or I'd gone for the APR or Hotchkis (27/27 mm hollow).

H&R advantages:

- excellent Quality
- very stiff (28/24 mm almost 3 x stiffer than stock)
- Teflon lining bushings
- TÜV


Before I got the H&R I thought a stiffer ARB in the rear is more important.
So first I adjusted them soft front and stiff rear.

But this wasn't the best for my car and my taste. The stiff setup front & rear
improved turn in without disturbing traction too much.

But this is choise and my taste.  :wink:

It depends from the suspension as well. There will be a difference between
stock and a KW Clubsport.


As well important:
Whiteline ALK, TT arms and hubs, performance tyres like PSS or even semi slicks.

... I'm not sure about the TT arms: I don't see how you can avoid some uneven tyre wear if you add camber ...

RedRobin, VW advices camber up to -2.15' on the back. If they say this is normal, I don't think we should be concerned going to that value (even in the front). Also under cornering the camber changes and we get more positive results.

....Yes, but there are reasons why the Mk5 GTI has more camber on the back than the front.

I'm getting my car aligned and tracked on a Hunter rig next Wednesday so I'll report what I'm advised about cambers.

what he is saying RR is that if the cars can run -2.15' on the rear without accelerated tyre wear or uneven tyre wear then it will be fine to use that amount of camber and more on the fronts. 

and Ian has already mentioned why the cars run more rear camber normally

As I understand I have TUV for both bars instead of one for the whole kit.
I just didn't like the available kits and wanted something in between. And so I ordered the bars separately (this was more expensive, of course).
