So hot here, I can't think. Point is that the foam stops act as extra springs when they are contacted. I just hope my ride won't be too stiff with my 450/500 combo. Of course it will feel like a cushion after bouncing off the stops for several months. I have the stuff, just too hot to work out there.

Message-ID: <[EMAIL PROTECTED]> I was wondering how anxious you'd be to try three years of 12-schools-per-year again in the same now-out-of-warranty, 19-year-old 951. ;-) Chris Eck On 7/15/06, Phil Marx <[EMAIL PROTECTED]> wrote: > >Kathy Lyle wrote: > > > >I actually spent 3 years (1987-1990) running an '87 944 Turbo at drivers > >schools, an average of ~12 schools per year.
