I have been driving a 1.2 Sport for six weeks and find the ride pretty poor and jumpy.I have 16 inch wheels.I am contemplating fitting Eibach springs which seem from other reports to help the ride and handling.I know this subject has been raised before and apologise for any repeat but would be grateful for help and comments to the following questions-1)Do they really make a difference? 2) Elite have quoted £312 to supply and fit-is there anywhere cheaper in East London/South West Essex? 3) Is it worth sacrificing the warranty on the suspension?
