So I just upgrade last weekend from a fairly fresh set of stock (27) Nivos to the Euro Nivos (25) or lowered chassis R suspension. I am running TME lowering spring with Koni sports set to full stiff and WOW I can defiantly say that there is a big difference in ride. These Nivos seem to be well paired with the Konis. They are stiffer than the 27 and I can say for sure that they don't sit lower then the 27 either... I'm not sure if it's just cause mine are brand new and need some time to settle down, but my car seems to sit at the same height as before with the TME spacers.
I've mentioned in the past was I felt the TME springs in the rear were too soft and had always guessed that with the 25 would feel better and I was right, they seem to be very well matched to the shorter TME spring. I still might want to install a stiffer spring but for sure I wouldn't want to go much stiffer as I did with the 27.
One thing I had noticed since Hussein had posted about his TME set up squatting under hard acceleration, is that the 27 would squat noticeably bad. Enough that it would bother me. Well with the 25 I can say that it may still squat but nowhere near as bad as the 27... The cars just feels better planted when I take off. And I used to feel the back end compress and bounce a little over heavy dips on the hiway and that is virtually gone.
So if you are in need of new Nivos and have a stiff front suspension, the 25 are a very good match for them. I just wish when I got my last set of 27, I knew about the 25 as they are what I've wanted in since I lowered the car...
