The Motul Autech performs essentially identically, and if any tune works for those other GTR's, it surely works for the Motul, I promise. 👍
The Woodone is pure crap, comparatively. Needs a totally different tune as well.
Curious, what makes you go with max spring rates? Did it improve your times, or you just like the feel?
Yeah, I tested the Motul on a Road Course last week, while trying to develop that tune and it felt great, I was surprised. I haven't taken it to HSR yet, because knowing how the Stealth vs Yellowhat panned out, I can only assume the Motul will follow the same trend, but eventually curiosity will get the best of me.
Yes, the Woodone sucks.
Max spring rates at both ends, offered the best lap times, which could be potentially related to bottoming out. I believe I started at stock spring rates, and slowly increased front and back by 1.0 each test until I saw the trend that stiffer is faster. At that point I continued testing following combinations:
20/20 - 55.488
18/18 - 55.8xx
19/20 - 55.598
20/19 - 55.566
And some .5's in between as well, but 20/20 came out on top each time.
Granted, due to the extensive possibilities, there could be some leeway mixed with shocks sways and then softer springs that are better, but ever after all of the testing, I again went back to spring rates and tried to see how I could effect the overall balance of the car for the high speed corners, but there wasn't enough gains in feel, to justify loss in lap times. Perhaps if the ride height could go beyond 10, softer springs could yield positive returns, but it's unknown... Unless I remove the Full Custom Suspension... there's an idea...
From there, it was a quick test of camber at 0 all the way up to 2.0 where I saw a graph of gains until a peak point, and then a fall, a Sine graph if you will. There could be a point at which the graph Cosine's, but due to tire wear, I didn't feel the need to continue to 10.0, but I could.
After that was a test of 15-20 different shock combinations, where only the below could time in below .500:
4/4/4/4, 10/4/10/4, 2/4/4/4, 4/4/8/4(best feel), 4/3/8/4, 4/2/8/4, 4/3/5/4
Then sway bars were played with to reach the final lap time. What was odd with sways, is that nothing in between seemed to compete, the 2 fastest, were 1/7 and then 7/1. That interested me quite a bit.
I can admit one major thing I skipped in this test, and that was Toe. I made the assumption that tire wear, just got worse and worse as toe was increased, but... after the last 2-3 weeks of doing a lot of NASCAR, I've found that the right amount of toe actually DEcreases tire wear.
So, Toe and Chassis Rigidity are things I will be retesting in the future. I've already broken in the Chassis Rigidity car, and applied the same setup, I just haven't sat down and done the side by side comparison to see if there are any differences.
Downforce seemed to be where the majority of the testing took place. Trying to find the right balance, between front and rear, as well as aero and power. I believe 30/40 actually gave the best lap time, but it was much harder to drive, and since it was purpose built for 30 lap races in mind, I went with the easier and more consistent option.
Your FTO Super Touring Car, and Nissan GT-R Concept LM tunes are absolutely brilliant. Thank you.
Thank you!
