Does anyone have a reference to find the center of gravity for the '09 GT500s? After measuring the contact points for the rear suspension, it looks like my instant center is 84" in front of the front tire (I have 20" staggered rims - so the slope of my LCAs is surprisingly negative). I purchased Maximum Motorsports LCA relocation brackets and noticed they have three settings. The lowest drops the arms by 3.875", which will bring the instant center behind the front wheels and much closer to the neutral line. The problem is I can only guess the neutral line. I don't have four scales to weigh the corners to calculate the center of gravity - so I just guessed by measuring the top of the waterpump (24" high) and my clutch (89" in front of my rear axle). I'm going after good handling - not hard launches - so I don't want the anti-squat to be over 100%. However, if I'm wrong on the estimated center of gravity, my neutral pitch line will be wrong and my anti-squat ratio will be incorrect. Obviously, any reference out there would be for stock. I can adjust from that. The only Mods I have that weigh anything are larger/lighter wheels, BMR subframe connectors, and Shelby rear strut tower brace. Below is the graph after measurements. The only piece estimated is the green line (neutral line).
