Hi Chris, the mid year 9000 flywheels are the same basic dimensions as the earlier 9000 and C-900 flywheels. They do of course have a larger bolt circle for the 238mm clutch but the other difference is that they are 3mm's thinner. The whole 3mm difference is taken from the clutch side but you can still remove quite a bit from the back and a little from the outside diameter. My overall opinion on lightening Saab turbo flywheels is that is does make a noticeable difference. In your application I lighten the flywheel to a safe maximum weight even though it's lighter than the early flywheels simply because your clutch is heavier than a 228mm clutch. I can send you spec's and pictures on where and how much material to remove. Take care, Dave
