FK-AK for comfort
JOM for more stiffness
Reason of how why I know this, me and a friend on here (S-l-i-x) had coilovers fitted at the same time

I went JOM, he went FK-AK. FK-AK is an improvement over stock and still retains comfort, at any point if you want to stiffen up, just lower the car

I know shocking eh?
With the same drop the JOM's are a lot harsher, personally if its a daily and you want some improvement followed by comfort FK-AK is the way to go and for around £165 I couldn't fault them.
