Total Lateral Load Transfer Distribution

[Sleeper68]

I'm not an engineer, I think it's important to note that. I am a firm believer that most push on entry is driver induced and have beat that drum for years here.........but you say it's tight everywhere and worse since you made the change in roll center.

That's not a huge change in roll center and I would have thought it would have been offset by better camber gain. Conventional theory would be with the higher roll center the car would want less spring or bar or both to get the roll rate back in line with the weight transfer at that end. This is math I have never done but comparing lateral weight transfer on the front before and after the RC change should tell you what you want your wheel rate to be in roll and then you can make an appropriate change.

Understeer through the middle is the worst......can't mash the gas if you are waiting for the front end to point the right direction. In general, loose is fast, you just need fast hands to keep up with it. I don't have those so neutral to loose on throttle is easiest for me to drive.

I also thought the camber gain improvement (from -0.35°/in to -0.78°/in in bump, right off ride height) would offset the RC change as well. It appears I was wrong. Yes, I could reduce the front spring rate or front ARB rate to soften the front back up. My thought was to raise the rear RC up to match the front to get the balance back. The overall roll gradient would be less but not by much. The better camber gain curve should allow for less static camber with the stiffer total roll rate.

And yes, it was awful. The entry understeer made slaloms hard. Had to use alot of throttle and brake to get the car to rotate which made me sloppy.



The push in the pictures above was also annoying for the same reason you said. Made it hard to get in the throttle early. I tried to use throttle steering again which sometimes made me push out more than I wanted.
