Where are you racing? If its at BRR there are plenty of guys there that can help you that have that chassis. If its at the Grove I am pretty sure they are actually 1550 for VTA. I race at both but mainly BRR. I had an old HPI pro 4 that needed 225g added to make weight. Just get the stick on weights and place them as low and as centered as possible. I have some in front and behind battery and under steering rack. I have 5g behind the motor. My VBC Wildfire comes in at 340g at each rear and 325g for each front. The body weighs about 125g so that brings it to 1455g for legal ROAR VTA (thats what thry run at BRR). If I get back to The Grove, Ill just add more weight.
Good luck and have fun. Youll figure it out
