octavia remap and suspension renewal

Ive just received my ecu back from Ecu Evolution and my god what a difference it has made.!!! I have been running a tuning box for the last 18 months and thought that that was good but this is something totally different for me.the car flies off the mark and the increase in torque is phenomenal (even tho its only a 90 bhp) so im really pleased with it. At the weekend ,I also fitted new front and rear suspension (shocks and springs) and it has lowered the car by around 30 mm,which has made it look more agressive.Ihave 225/45x17 tyres on all round but will I be able to carry 4 people with luggage ok , or will the arches catch?The rear feels quite stiff so hopefully it will be ok.When removing the rear springs I found that BOTH of them had snapped about 2 inches of spring off, so it was a good job I did change them
