Re: 156 Wheels and suspension?
Don't kid yourself that as low as possible will give better handling. It won't. Lowering is primarily good to lower the centre of gravity and hence reduce the roll angles the body experiences whilst cornering. It can help induce more negative camber on the wheels, but this will have an adverse effect on tyre wear and life due to inner shoulder wear.
When the suspension is very low, the springs and dampers are too firm in order to resist bottoming out, and tyres the have reduced road contact on a rough surface commonly found on UK roads. Very low is only useful for smooth tarmac circuit racing where the racing line does not involve taking kerb.
Most kits will lower a Sportpack car up to 25mm despite claiming 40mm. This is because it is true only for the non-sportpack suspension. Any lower means too large a compromise on spring rates to keep it from bottoming out. I would recommend minimal lowering for real world handling improvements. If you don't want a reduction in ride quality which you wiil experience when lowering the car, then Koni FSD dampers without lowering springs are the way to go. Eibach springs will also work with this setup. Failing that a Koni kit will help, but you will have more road shock enter the cabin.
I don't recommend wheels larger than 17. The extra unsprung weight and inertia will have a negative effect on handling, ride and performance.
