Since when is this a bad thing? I thought this was the cornering-forum?
I was oversteering way too much at Sonoma particularly at Turn 2 and 11 near the walls haha! Was able to dial it out though.
I'm pretty sure my weight split is still around 55/45 front/rear and want to shift more weight to the rear where it is the lightest. I don't need any more weight in the center as I have a 200 lbs/90 kg roll cage there.
Moving static weight towards the car's CG is almost always beneficial, if your weight distribution is reasonable. But yes, getting it off of the front in these applications is best. If you aren't familiar with it, you may want to look into moment of inertia (polar moment) and further understand how weight away from the CG is like a lever in turns, trying to rotate the car before changing directions. Weight in the center of the car is not as effective at changing weight distribution than in the trunk, but it is certainly better than it being out front.
