Back to the math class black board. But for clarification, heres what Herb writes.
For those who know more, this will probably be old news.
Total cornering force=traction available(from tire performance curve) divided by vertical weight. This will give you, in theory, how
many g's a car will be able to do.
Lateral weight transfer(factored at 1g)=overall weight x center of gravity height/track width. This will give you how much weight is transfered in a turn of 1g. Resulting in how much weight will be added to your static,at rest,corner weights.
Total cornering force is an average of the front and rear suspensions. If you apply the same formula to both the front and rear suspension separatly, you will see how balanced the car is.Using the numbers I posted earlier,(1.005g's front,1.125g's rear),says that the front will not take as hard of a turn as the rear,therefor on paper it will push. If these were
bass ackwards there would be oversteer. If they were equal or closer, it would turn better and probably faster.
I will be upping the spring poundage to around 550# and set up for the old reliable 1.25 front/.875 rear to start until I get more accurate corner weight and some tuning time.
Does anyone happen to know where I can find corner weights for an early Chevelle w/ BB or SB? Total,front and rear weights would be useful, for future reference also.
Thanks, Doug
