I got my replacement rear springs in Friday and haven't had time to post the particulars, but wanted to do it for historical info should anyone read this thread fifty years from now....

The standard Ksport Koilover setup has the following spring rates on their units designed for the Porsche Boxster:

Front - 5.3 kg (stamped 10.5-205)
Rear - 9 kg (stamped 11.5-180)

Insite has recommended that anyone buying a set of Ksport Koilovers for their Boxster should order them with a special request for a different spring rate on the back struts that is closer to the rate of the fronts.

So, the change one would make would be to ask for the rear struts to be fitted with 7.2 kg springs that carry a factory stamp of 11-180.

I know the factory numbers between the 9 and 7.2's are very close (.5) but I verified this twice with Anthony in sales at Ksportusa just to make sure they are 7.2's and not 8's or 8.5's.

And that's all I have to say about spring rates right now. Bye.
