I think that is weak too high, there is not much real weight in the glasshouse, most of it is in the rails, motor, rear beam As an educated guess/rule of thumb, US front engined RWD V8's use the the centre of the cam shaft (in the Vee) So using that and considering we have allloy heads maybe the mid point of the motor, you would think it would be OKwithin 25 mm or so
I'm looking at structurally optimising a Mk2 Golf control arm, and as part of this require the torque at the ball joint. I am basing my CoG at 675mm from the floor*, and the centre of the ball joint is 175mm from the floor. As I saw you have mentioned earlier in this thread, T = F x D. With that in mind...my total weight of the car is 11359N and when braking, this force is trying to effectively turn around the ball joint. To calculate this: T = 11359 x (0.675 - 0.175) = 5679.2/2 = 2839.75Nm I am having trouble with my model when analysing the control arm using this torque figure - The stresses are massive and there is no way the part would be suitable, this is even before optimising. My question is, does anyone know roughly where the CoG of a Mk2 Golf is? I have based the weight distribution front/rear as 64/36 as I can reference this from a book I found. I understand how the CoG can be calculated but do not have time for this. Any help would be massively appreciated. *The CoG I have used of 675mm from the floor is around the main swage line in the door. Cheers

I was more apologist to invest in an ABF 16v, but what a project !! congratulations! I like all the details, that support gearbox even in total weight reduction .. eeheh
1986 Golf 2 GTI 16v 9A engine with ITBs Removed seat mountings, also rear seat bench. Lightweight battery in the rear. Lexan windows rear + rear sides. Full cage, fire extinguisher. Full tank: 989 kg. But it's already a few kg's lighter due to a smaller alternator and mountings.
