You may think it's too troublesome to keep changing the settings on Ohlins suspensions...

You don't have to do that... You can tune the suspension to even 1-2 click softer than my settings.

(it's still very good with softer settings)

However, I really want my Ohlins suspension be on the borderline between comfortable and too stiff... Why??? That's because I want my Ohlins suspension to be as fun as possible...

(also as refined/less bouncy as OEM suspension at the same time... Of course, it's IMPOSSIBLE but I will try my best!!!)

You may ask why Ohlins didn't adopt softer springs for their DFV suspensions...

If they adopt softer springs, then Ohlins suspensions could not be so much fun!!!

In addition, I think Ohlins are confident that their fancy dampers can be matched with those very stiff springs just fine!!! (we just need to get used to those higher natural frequency suspensions)

Believe it or not... In low speed city traffic, the big Brembo brakes with OEM pads from my GSF are not as good as my wife's M35X's much smaller brakes with OEM pads especially during the winter!!! (GSF's pads need some warmup)

The OEM pads from my GSF feel like Hawk HPS pads which are not as good as M35X's OEM pads in low speed city traffic but work better on high speed highways....

As my GSF is a performance car, it's really reasonable that Toyota/Lexus engineers more focus on high speed braking for my GSF...

Maybe the braking distance is not so much different between GSF and M35X...

However, I have to admit that the pedal feel from my GSF's big Brembo brakes is WAY better!!!

(It feels so solid and its free play is so minimal)

The minimal free play of brake pedal:
2017 GSF > 2010 M35X > 2007 G35S (M35X's brake is still very good but just not as good as GSF)

The below is FIGS Ohlins TTX suspension the price of which is about double of my Ohlins DFV suspension and mainly used for tracks...

FIGS Ohlins TTX

Is this TTX suspension much better than my cheaper DFV suspension???

In my opinion, the answer is YES and NO!!!

If you check the spring rates for TTX, you can find the spring rates(18/14K) are not much higher than my DFV's (16/12K)...

This TTX is mainly for tracks. However, the spring rates are not much higher than my DFV's. This means the damper technology used in DFV should be quite similar to that in TTX.

If the suspension is mainly designed for tracks, it should adopt much higher spring rates as race tracks are very smooth most of time...

However, this TTX suspension doesn't. (Its spring rates are just a little higher surprisingly!!!)

Believe it or not... In fact, even Lexus Racing USA uses these same TTX dampers in the IMSA racing RC-F GT3 platform... rock

(You can also see these TTX dampers at 1:55-2:00 and 3:18-3:30 in the below video)

You may ask why TTX is so expensive...

That's because TTX provides more adjustments and those additional adjustments could be vital in making the fastest lap time!!!

Of course, I don't need those adjustments because 0.1 second difference in the lap time is totally nonsense on public roads...

In addition, even though I track my GSF, the first thing I have to improve is my driving skill, not my DFV suspension... (My driving skill is not at that level yet, of course!!!

)

So, let's back to my question "Is this TTX suspension much better than my cheaper DFV suspension???" The answer is...

"Yes" for any professional racing drivers who try to make the best lap time.

"No" for at least 95% of the drivers who are average drivers like you and me...

Actually that no.14 RCF GT3 is quite good...(although it's not the fastest, it still got the 3rd position in the class at the last)

It also ran against some very expensive cars like Lamborghini, Aston Martin, etc. rock

After I watched those RCF GT3's videos and found how good it was with Ohlins TTX dampers, suddenly I think my investment on the DFV suspension is really worthy!!! 拇指向上

Of course, the engineers working on that RCF GT3 could put much stiffer springs and re-value the dampers but I believe the damping technology used in DFV and TTX should be at very similar level except TTX has more flexible adjustments!!!

Actually less adjustments are very good for ordinary people like you and me because less adjustments, less faults...

Of course, we should still keep the ride height and overall damping force adjustments as everyone's taste on them could be very different!!!
