Hi, sorry haven't looked at this thread for a while.
Have lost most of my old PMs in the recent purge. But going from all the others I've previously done, I'd estimate that depending on preferred level of comfort, you'd need a 700lbs/inch (120 N/mm) or 725lbs/inch (125 N/mm) spring.
If you're after a 120 N/mm spring, there's a guy on ebay currently selling a load of K-Tech ones that fit - I assume he's either a trackday addict or a racer! Search for 'Ktech Shock Springs 55-155 Multiple Rates Available' or type eBay item number: 186726839773
