Wondering if anyone has attempted to tune the 92 Nsx and noticed that the suspension does not appear to travel past 70 percent on the telemetry when softening the springs for grip even when all the dampers are set to 2.00 and the anti rolls are also set to 2.00?
I will admit that I did lower the suspension before starting to soften the springs so I am wondering if this is one of the few cars that you cannot slam the suspension on.
If it is one of those cars then how do I proceed in tuning the suspension considering that I usually soften the springs as much as possible in order to get best grip and compliance and have never tuned a car with this characteristic?
i never slam the ride height on any car i tune as it bottoms out and find that cars fully slammed tend to slide more in bends on entry and exit… thats my way tho and everyone is different i guess
no problem also with aero it forces car lower and doesnt allow enough suspension travel so have to accomodate with stronger springs or ride height, just another thought to try
I tried driving this car at Nordschleife using default spring rate (pretty high, ~700 lb/in) and it does not bottom out at all but drives extremely well. Usually the default spring rate is too harsh but the car was handling impressively.
‘Slamming the ride height’ seems to have no noticeable affect in FM which is mysterious. It is detrimental to the car as well as handling not to mention your spine but in FM series (and many other sims) the impact is hardly noticeable . . . curious . . .
I’m going to try softer springs and see what happens. It is not a fast car but handles beautifully.
At any ride height the suspension needs to be fine tuned to prevent bottoming out. Lowest ride height on most cars does not result in bottoming out provided springs and damping are tuned accordingly.
I need to revisit the nsx to check what is going on there.
Thanks for backing me up a little Eduardo i thought i missed a trick since all the previous posts are saying that they don’t slam their ride height when possible. I do it to lower the cars center of gravity and for the cars i tune i do feel a positive difference in handling.
So when i decide i really want to get the maximum travel and grip out of the springs i bring the car to a relatively flat track (Silverstone GP) run laps and make adjustments until the car is consistently hitting high 80 to low 90 percent on the suspension telemetry at both ends of the car mid corner when the car is not accelerating or decelerating with all the other factors removed (ARB/Damping). This car at the lowest ride height would not past 70 % on the telemetry when the springs were softened up.
Added to that the car had some extremely weird handling tendencies at the entry and exit stages of the corner but instead of diagnosing it as lack of suspension travel and the suspension hitting its limits at the lowest ride height i figured it was something else that i could tune out when i got to the handling stage of tuning the car.
Then i thought about it and figured it could be a ride height issue i decided to keep the lowest ride height and bring the springs back up just a bit stiffer… That didn’t work because to maintain the lowest ride height for this car the springs would have to be stiff to the point of introducing instant grip loss and harsh ride even though ive lowered the bump and increased the rebound to match.
I’m sure someone can tune it to behave while keeping the lowest ride height but i don’t have the time or patience
So i have decided to compromise a bit and bring the ride height up one notch … Car now handles up to 95% to my liking and based on the build this car is already shaving off some nice times off my personal bests.
So i presume this is one of the few cars that you cannot slam the ride height on and the spring rate needs to be a bit on the high side but overall the car works great.
I just wanted to know for cars like these that you cannot easily tune using the standard procedure (Softest springs / Lowest COG) what the alternate procedure would be. I Guess the only two options are to stiffen springs as long as its not detrimental to grip and handling or raise the ride height to facilitate softer springs and more suspension travel at expense of not having the lowest COG.
