Why is there such a big difference between the weight of each part produced from the same blueprint?
The chassis is the worst offender in this case, as in 15kg heavier than what is stated on the blueprint.
The other parts can show between 1 & 2kg at times, (depending).
I don't mind 1/2 kg here & there, but producing a gearbox at 45kg & the next one is 47kg from the same design is totally sackable in F1. lol.
Now that i have just upgraded my chassis & all 4 that were produced from the design are quite heavier than what is stated in the design.
2 of them are 14kg heavier than the blueprint weight, 1 is 15kg heavier & the 4th one is almost 20kg.
What is going on?

I have to agree, while slight variations in weight are acceptable some of those i have seen so far have been pretty insane. Maybe the variation needs to be adjusted a little as without adding ballast i cant see how any chassis can be much more than a couple of kg heavier than the design...

That said i dont work in F1 or racing so may be missing something completely... lol!

I agree. There should be some allowance for how go your mech is who is making the parts. But really they should be fairly close

My current theory about the weights is that it is a percentage that the weight can vary. When you are working on a 12kg suspension for instance a few % won't make much of a noticeable difference. The chassis however is over 400kgs so even if it is say a 2% variance then you are looking at 8kgs+

Does the difference that weight makes vary depending on the part? Will a 10kg heavier chassis have the same impact as a 10kg heavier suspension?

Yes, 10 kgs is 10kgs no matter where it is placed on the car. Based on someone else theory and I have tested this a bit a 10 kgs car is at least .500 slower.

I think you can simple test this by fuel weight added to a car to control the data that you get back, but I believe it was .500 seconds

I've noticed as you improve the parts the weight improves and the variation in weight is less too. - so sorta like refining the error margin i suppose, not really realistic but i can live with it
