This Evo is also equipped with Ohlins DFV... Does it ride similarly as my current GSF does??? 笑到噴淚

(I also believe the ride frequencies of this Evo and my current GSF are similar... Just like many other cars with Ohlins DFV!!!)

PS: Actually I believe my current GSF should be more comfortable as I upgrade my GSF tires' to +2/+1 sizes(increase sidewalls) and also lower the tire pressures...

This is a Panamera Turbo S which is the most sporty 4 dr car from Porsche... (It is definitely not as bouncy as other supercars)

Panamera Turbo S

This is a stock GSF... (Both my wife and I think this hardcore Lexus should be firmer than that Porsche!!! i.e. more bouncy)

GSF

This is EVO 8 with Tein lower springs(15-20% stiffer than oem) and oem dampers... (only 15-20% stiffer but already as bouncy as supercars!!! 嚇到吃手手

)

This is EVO 7 with Ohlins DFV(150% stiffer than oem)
So, the ride frequency of this EVO is much higher than the EVO 8 above and also more stable!!! (still bouncy, though)

PS: I also believe the ride frequency of this Ohlins EVO could be as high as 911 GT3's!!! (just like many other cars)

In addition, 100% stiffer in springs = 41.4% higher in ride frequency...

This is an EVO 9 with Ohlins again...

(You may wonder why this EVO didn't bounce like my current GSF??? That's because this owner also changed the seats which should be a bit harder than OEM seats . So, the driver and the camera bounced simultaneously with the car!!! 笑到噴淚

I just found this very interesting video about Ohlins vs stock suspension... 拇指向上

In the video you can see the ride frequency and the gain(body movement).

-- Medium bump --
Stock: frequency = 1.75, gain = 1.5(avg)
Ohlins 2F/2R : frequency = 3.125(avg), gain = 1.5(avg)
Ohlins 20F/20R : frequency = 2.5(avg), gain = 1.75(avg)

As you see...
1. The ride frequency increases by 40%-80%. (Very stiff damping could also increases frequency)
2. The body movement could be maintained like stock, if Ohlins dampers are set at very stiff settings. However, those very stiff settings are very uncomfortable and unpractical on public roads. Except those very stiff settings, Ohlins will always has more body movements than stock as its spring rates are so high... (just like bouncy supercars!!!)

PS: Please ignore the shown numbers on frequencies in the video. The real ride frequencies are definitely not that high. You can only focus on the changes for frequencies...

Now I think I know why those supercars have short lifes...

That's because the suspensions of those supercars are very stiff. Running your engine at a very high rpm on a very stiff suspension... Of course, those engines will not last long!!!

I have to say this again... These Japanese cars are really amazing!!! My son's G35S has been equipped with a very stiff suspension since 2010. Now, its mileage is over 200K kms and its engine still don't eat any oil!!! 嚇到吃手手

PS: You may think I'm lucky... Actually I had done the same thing on my previous car, 2000 Maxima... Same amazing!!! (I will also do the same thing on my current GSF... Time will prove this... AGAIN, I believe!!! 笑到噴淚

Now I understand why my wife didn't like an almost brand new 2010 M35X in 2011... 笑到噴淚

The H&R springs in 2000 Maxima were only about 15-25% stiffer than OEM springs(the ride frequency should only be a little higher). However, I did set those Koni Yellow dampers to 85%-100% stiff!!! 嚇到吃手手

(I was dumb!!! 笑到噴淚

)

Therefore, very stiff dampers could increase the real ride frequency in that Maxima a bit like 2.0.

You may think 100% stiff Koni Sport dampers could be very uncomfortable. Actually it's not that bad... I drove that modified Maxima and did a lot of long trips around Taiwan and my wife and my children still slept like a pig during the trips!!! 笑到噴淚

(So, the seats from that Maxima should really feel like couches!!! 笑到噴淚

)

The below videos is from Koni... They say "There is no best settings for Koni Yellow dampers!!!" It all depends on your "driving style"!!! rock

I prefer the stiffest setting... (I was fooled by those comments like "Japanese cars are too soft!!!")

However, this guy prefers the softest setting!!! (he think his Japanese car is TOO STIFF!!! 笑到噴淚

)

-------------------------
This situation is similar to the below...
In the past, Japanese cars were lighter, many people said "Japanese cars are too light!!!". Now, Japanese cars become heavier, many people say "Japanese cars are too heavy!!!" 沒有不敬的意思
