I'm looking to upgrade my S2 and have an opportunity to get the Turbo S springs and was wondering how much stiffer (if any) they are.

Thanks.

Thanks, that's just what I was looking for. I'm suprised that the Turbo S only has about a 30# stiffer spring than the S2.

You will also want to ensure that the turbo S M030 springs will fit on the S2 struts. The M030 springs have a slight taper to them, and may not work on S2 strut lower perches.

I am not familiar with the stock springs/struts for S2s, but I do know that the turbo S M030 springs do Not fit on standard 944n/a, S, and turbo struts.

springs really aren't that expensive by themselves, you might just want to look into get some aftermarket springs as the turbo s springs really won't be that much of an upgrade

944 S2 and 968 springs have the same outside diameter (106 mm) and can be swapped. Put differently, 944 S2 and 968 struts are physically identical.

NA/951/S springs have a bigger diameter than S2 springs and do not fit S2 struts (1st hand experience, but I did not measure the outside diameter back then).

M030 springs outside diameter varies between 110 and 124 mm so they won't fit S2 struts since their diameter is too large (at best, 110 mm > 106 mm).
