Folks - I have had the Suplex front for the past 3 years and actually would not have a Mog without it -- for my style of driving, and I stress, my style, it transforms the car and ensures that the front goes exactly where I point it on bumpy Irish secondary roads.
So--- I have just had the rear Suplex fitted and, while it is early days, I am delighted with it -- again for my style of driving and for the roads on which I primarily drive, the ride is much more compliant and the car handles just as I like it. I agree that for those who really push the performance - mine is a Plus4 - it may not be "visceral" enough, but for me it is a really good step forward.
Thanks to the Williams boys who seem to have the installation and set-up nailed -- they took great care - and even vacuumed my car out when they finished!!!!!
Cheers!
