Default Interesting difference between stock WRX clutch & OEM Exedy replacement...

I tried doing a search & came up empty handed on this one. I recently installed a new Exedy OEM clutch kit in my '02 WRX. One thing I noticed is that the old disc had a sort of double spring setup with one small diameter spring inside of the larger one. The OEM replacement just has a larger single spring setup. How will this affect drivability / performance / feel, etc?

The OEM clutch has a finely tuned spring rate that they achieved through using two springs. The Exedy replacement only uses one spring to get the same effect.

I'd put $5 down that I wouldn't be able to tell there was a difference between the two. I don't think there will be any difference in driveability or performance.

Could it explain the annoying deceleration noise that some people get? Including me.
