Maybe it's caused by stainless steel brake lines on my G because steel brake lines will not expand but rubber lines will. So I need to use more foot force and wait a little more time to compensate the expansion in rubber brake lines, I guess.

M5 : speed, stable, comfortable
GSF : precise, light, nimble
M5 is just like a speed machine which loves speed. The higher speed the better.
GSF likes mountain roads more.
So I think that's why very few people buy GSF. GSF has high power but cannot match high speed stability from M5.
In the other hand my GSF's handling is excellent. It is very good at mountain roads. Therefore buying 86, Miata, Civic Type R, STI, or EVO would be more making sense, I think...

So no matter how good your car is. The people who are not afraid to die are the fastest. (不怕死最快!?!)

By the way that driver in that truck must know that mountain road VERY WELL, I guess!?!
So the handling in Japanese cars actually is quite good. They just lack some good damping force at higher speed to stabilize their rides. If I can put better dampers like Koni, Bilstein (A grade) or KW, Ohlins(A++ grade) to stabilize my GSF's ride at higher speed, my GSF should feel much better, I think.

PS: I think Sachs dampers are only for ordinary European cars. To compete with performance cars like M5, E63 AMG, my GSF must be paired with better dampers. I don't think M5 paired with average Sachs dampers could produce that super stable and comfortable ride on the highway. That M5 must come with super advanced dampers(specially tuned by BMW engineers and only for M5), I guess...

Thank you. You are very patient in reading my POOR English.
This is only my thoughts. They may NOT be right!?!
I LOVE cars and like to talk about cars all the time. In reality I think no one likes to hear those detailed, tiny sometimes not correct comments.

Thank you again...

By the way after I've told my wife my review on M5, She seems to really want to drive one to feel the differences (She wants me to rent one)...

I had tested GT-R before. I think GT-R is much more stiff which is very good on smooth race track. However, on public roads(not perfect) I still think M5 should be much more stable and better... (I never try recent softer GT-R but I think BMW's suspension is not easy to beat!?!)
In addition I guess Porsche Panamera should be M5(high speed stability) + GSF (precision). I really need to try one to find the answer...

PS: In my opinion precision on my GSF is still the best even comparing with Porsche. Precision on my GSF is just like BMW's suspension. Both are NOT easy to beat, I guess!?!

That's why I keep changing my European coilovers every 3 years. Now PSS10 damping ability becomes weaker and steering also become loose a little bit.
I think those European coilovers are quite good. They actually can compensate the old and somewhat loose suspension on my old G. I never try any coilovers from other area than Europe with one exception. The exception is Tokico performance shocks which was adjustable like Koni yellow but I didn't like it at all and in my opinion it's inferior. So I cannot comment any coilovers other than Europe, (Because I don't want to bet on them. I may loose my money again...


I just replaced my Wife's M35X rear dampers with KYB black GR-2. In my opinion the new KYBs are worser than OEM Tokico because I think KYBs are much more stiff but don't improve stable ride. (maybe a little bit) Those KYBs are just cheap OEM replacement and not performance shocks. So I should not ask too much on them!?!
