After looking at various coilovers decided to go for FK Automotive which look great and use Koni internals. Have a great warranty too.
Found a place called http://www.performancedriven.co.ukwww.performancedriven.co.uk and they sell the non adjustable version for 480 quid, 630 for adjustables. Also for a limited time only they are offering free fitting which cant be bad and would save a hefty sum.
Gonna order mine this week but have to wait for delivery in January.
