ok had a chat with supplier this morning
4x 14-9.5 gaz with 4x any rate 8 or 9" springs would be £264.08+vat and 10 p&p (i make it £326.89)
kit quoted was cheaper as springs suppied are cheaper as thay are shorter and not in the same price bracket
thay would have been happy to keep the kit same price as long as the all the bits where the same price
all shocks in that size in stock and guy seemed to think spring rates would be in stock in most rates
