@ tasty kebab...
A decent set of Coilovers will be fully adjustable...
This means you can adjust the Ride height (Lowering), and Rebound (Softness/Bounce over bumps etc).
Therefore you can customize the suspension setup to your exact preferences.
Regarding Spacers...
I was told that Spacers are not a good idea, as they will never be perfectly mated to the rear of your Alloy wheels.
Therefore, when/if you hit a pot-hole hard for example, you can knock the Spacer off centre to the wheel, which can actually make the wheel not run true!
Am also tempted by Spacers, but still looking into the options out there.
Is it really true that the Front wheels (as factory), are set wider than the rear!?
