Total Lateral Load Transfer Distribution

[dontlifttoshift]

My camber gain is more aggressive than yours and I run -2.7* static with about 7* caster. Yokohamas want more camber yet. Pic is on Goodyears and while it looks a tick positive, the tires wore well all weekend.



I would soften the front before I raised the rear roll center. In general I want to work on the end of the car that is not working......removing grip from one end to make the other feel better is not the way to go fast. If the front sucks, that's what needs fixing, then work on the rear to find more speed. However...



You already made changes so lets see what happens.

Car looks good in that corner. Rear is not rolling much more than the front. Outside front seems very happy. Inside front has a lot of camber to it.

This is close to how my car cornered before the change. Looks like your setup is stiffer than mine. My ride freq's are pretty low compared to alot of others, about 1.5Hz front 1.5Hz rear. This correlates to 600lb/in front springs and 185lb/in rear springs with my corner weights and motion ratios. Wheel rates: ~210lb/in front , ~100lb/in rear.

I essentially made the front a little stiffer, in addition to the camber gain improvement the car needed so I could run less static camber. I ran about -3° camber when I was on 245s. I went to less camber with the 275 Rivals to improve braking because the car would lock up the inside front badly before with so much static camber.

Why do you think the front sucks? I see it as the front and rear are not jiving well together.

Let's say my roll rate before was 3°/g front 3.5°/g rear and now it is 2.5°/g front 3.5°/g rear. The much stiffer front now could possibly be the cause of the understeer.

Now let's say your setup is 2°/g front 2.5°/g rear. Your setup is still stiffer than mine, but since the roll rates are more in line with your car's static weight distribution the balance is good.

So one could argue that by making my rear stiffer, I improve the balance of the car. This doesn't necessarily mean I am removing grip from the rear because my setup is still softer than yours.

Obviously the numbers may be off but I think this is what is going on. What do you think?
