If you decide you want matched springs and dont mind going lower then Spax springs are available on eBay for about £180 .
Slightly less if you deduct the Nectar points X6 for a limited time only.
I've always found Spax springs to be slightly softer than other aftermarket jobbies and they work well with every gas shock that I've tried including KYB,Monroe Sens-a-trac and Bilsteins..
