Right quick update Boxster now sorted & sitting on an original Porsche Techquipment kit so new stiffer shocks, springs all round then stiffer front anti roll bar & rear anti roll bar. Oh & 4 new drop links as the old ones were destroyed to get them out & what a bloody nightmare to get out with the steel bolt bonded solid to the alloy hub unit & taking 3 of us wrestling with each corner applying heat & hanging of a 24" power bar & an impact gun on other side (steel & alloy?Not the best idea the Germans have had). Managed to do the rears without having to remove driveshafts etc so that saved some time.....
But all the effort was well worth it as car now handles like a dream

& should be even better once I get the geometry checked.
Ended up using Design 911 as their prices werent bad but their packaging of products is shocking!!
Thanks for all the advice given
