So did you only add ballast to reach the min. weight? It has been a long time since I scaled my car, but to reach th 51% rear that I am at now, It seems like I have 300lbs added. Maybe I should try a little less rear percent, cause I have never had any forward bite issues.
I have seen these metric cars dominate with 500lbs added for rear percent, and I guess I figured rear weight could only help.
