I'm thinking of putting some 30mm eibachs onto my SE to hopefully get rid of the squidgy ride after fitting 18" wheels. What sort of costs would I be looking at to get them fitted? Ive had a couple of quotes ranging from £160-260 so I'm not sure what would be reasonable. I'll be warning the garage about the pinch bolt and to take the suspension leg off instead to save time. Apparently the rear springs are a nightmare to change??
