How long does it take for the brakes to bed in? im itching to give them a good testing

@ newsh... u sure u know what u are saying? cause a lower car = lower sense of gravity = prevents car roll and helps traction to a certain degree ....

I was also referring to possibly the h&R springs wit bilstein arrangement .. would it be cheaper than the ones above?... if about the same ... which is better?

You can go for reduced suspension travel to give less roll but there is a trade off, the car will not absorb bumps so well and traction will be reduced on bumpy surfaces, better to use stifer ARBs.
Lowering the car will change the geometry, it will especially change the angle beween the wishbone and the road, if the wishbone is flatter to the road it can actually give you MORE body roll than if the car was not lowered, theres a very good article about this somewhere on the web.

You don't really need stiffer springs with Billies, they are stiffer anyway, air assisted..

Ill get saving, probably go for the koni and h+r setup as thats what i have on my UR and that works well.
@Dan,the tyres are 225/45/17. What tyre pressure should i run these at?

I have same as you, S4 with 225/45/17, 36 psi..
