I know this is a old thread, but in you pic of the rear SHP strut housings in post #7 it looks like they are about 16.5 inch tall.

Do you remember how deep the inside was?  16in?  What is the longest strut insert I can fit in the rear housing?

Thanks for your help

Decade bump! Actually, it's been almost 12 years since the original post, sheesh. This is still probably the best coilover DIY thread on the forum, though. Wondering if you're still running this setup and if you've made any more improvements to it over the years.

Also wondering how much droop travel is left with the shortened housings and what the ratio of droop to bump travel ends up being. Having a decent amount of droop travel is important on uneven roads and rough surfaces (a.k.a. the real world outside of race tracks). A wheel hanging in the air doesn't have any grip.

I actually havent done anything to them in 10 years!  They still ride fine, as far as I can tell.  Droop at the current ride height is around 3", so say you took the weight off the suspension, they would drop about that much.  Never measure how much up travel I have, but Im pretty sure Ive never bottomed out.  If I wouldve done it over, I would probably get KONI inserts and smaller diameter/easily available sleeves/springs like ground control.  I probably shouldve stuck with 7" long springs too, as a new wheel setup may interfere with the collar/perch up front.  I still feel shortened housings are the way to go since you have a bit more flexibility on inserts/valving.  I dont have to pull the whole setup off and shipped out for servicing.
