Don't you also have the STMPO front/rear brace? The ration of 600/500 is a bit skewed towards the rear but I let Billy address those details :wink:

It is amazing indeed to see how much effect moving the rear Dali 1" sway bar by one hole can make a difference. I found out that a few years after the first session with the 1" sway bars.

yes, I do have both the STMPO bars. But I can't adjust them. :tongue:

And 600/500 is pretty damn close to the type R spring rate ratio. 120% F -R. It's the same Chris @ SOS is running with the Moton CS on the white NSX. I know Comptech Pro is MUCH more front biased. 166% F.

WHEEL rate is what matters. Having a similar F-R spring rate % isn't exactly the same.

Does the NSX-T have a different wheel rate than the type-R? Why? Is it the weight difference?

No, it's the same:

EDIT: You do have basically the same wheel rates as the NSX-R. I had the wrong formula table up when I was making those earlier comments. I still think the rear bar might be too stiff.

The fact that the rear wants to come in the front at constant speed or slight deceleration in a turn is not really inspiring me. Even if it could induce some understeer, you took a good decision to relax the rear sway. I think you can compensate the little more understeer by tailbraking. Regarding the spring rate, I never understood the idea that a coilover X with 120 % rear bias in spring rate will overteer more than a coilover Y with 120 % front bias as it is nonsense to compare without knowing other parameters (compression and rebound of the shocks, weight balance, etc.). I have Tein Flex and never got (to much) oversteer despite the 10/12 spring rate.

Springs and swaybars affect steady state balance while shocks primarily affect and control roll during transitions. Shocks don't really affect steady state cornering much.

Trailbraking would most often lead to more oversteer on entry, unless you overload the front tires with so much braking and turning input to cause them to slide (understeer).

While its important to look at the system as a whole (tire size/compound, vehicle weight/distribution, alignment, prings, and swaybars, shocks don't have a huge effect on steady state balance.
