Sping life expected for 240?

Carl, same question as above, but for the Interpart Muhlhollands. I got a set a couple years ago as part of the refresh on my silver Z.

Carl,

How do you think your Euro Spec Stage I springs would work on a 240 with a set of NOS Bilstein p30-061 and p30-062 strut inserts?

The Euro Spec Springs are about 10% stiffer than US Spec springs - if you cut a couple of coils off to keep the same ride height - you'll be about 20% stiffer than stock - nonetheless that is still a relatively soft spring rate. I think the Bilsteins would be just fine with that...

Hi Bill:

If they work well with the OEM springs - they really should have a broad enough application range to work well with slightly stiffer springs, without blowing them out.

As I recall - BRE/Interpart used a couple of different OEM's to produce the "Mulholland" brand - the early one's were actually Koni's and the later one's were Boge. In both cases the OEM's part numbers are stamped into the body shell at the bottom of the shock. Sometimes that is covered up by the paint used to make them "Mulhollands"...

FWIW,

Thanks for the offer and info, Carl. I'm not too keen on cutting springs, so right now I'm leaning towards the Tokico spring/strut kit.

Does this mean that you will have the Bilstein's for sale? Also do you know what the spring rate is for the Tokico Springs? From my older notes, from Ken P. in 2006 - I have 120 lbs/in for the progressive rate springs and 140 lbs/in for the linear rate springs. Does the "kit" come with adjustable rate shocks?

FWIW,

Carl B.
