Senna miss this stuff?!!
- Thread starter TURBO2GO
- Start date
The chassis WAS pretty weak when Senna first drove the NSX and made that comment (as did Honda's test driver Tamamura). They later stiffened up the chassis immensely during their testing at the 'Ring.
I think the rubber was probably a lot stiffer back when it was brand spanking new and under development. The front compliance piece though was probably understood as a system to help comfort and driveability (which Senna said was very comfortable)
Just how I have played this out in my head.

yeah I know the chassis engineers then fixed the chassis, but I am surprised he didn't say "the car is changing rear toe under pressure"... I mean were these bushings changed later? Are they different on the R which he drove? Or are we over-stating the problem to begin with? How is it these weak points survived anyone's scrutiny until maybe before Comptech racing?
Its a production street car designed to pass NVH tests. Your wealthy target market isnt going to go for a stiff ride with monoballs. Rubber gets old so your bushings were better 20 years ago. Even now, my old bushings are working great on track. I dont think anything was missed but rather the standard compromises for a production car.
Hey whose bushings are you calling old?!! Maybe YOUR bushings are old, mine are still nice and tight... :biggrin:
Dave, the car was designed to be a COMFORTABLE every day exotic. If you go back and read all the reviews from the early 90s, the biggest selling point at the time was how great of a daily driver it was. It was never designed as a GT3 type track toy.

We've been down this road before.

On-topic, you also have to consider that the OEM 205/225 1991-spec tires were putting WAY less stress on the suspension bushings and pivots than the far wider and far stickier rubber most of us track junkies are running around on today. Also, for all his talent and possible mechanical intuition, Senna wasn't an engineer. He would describe a behavior or feeling or tendency, then it would have been up to the engineers to determine what caused that, and then how to fix it if it was deemed an appropriate thing to "fix".
