My car ran at Taplow at around 1700g and yes, to achieve that weight, I did have to 'tune' (
) it using some weight.
The small LiPo is about 100g lighter than the saddles I've mainly used during testing. All I did at Taplow was to use additional weight to bring the car back up to a weight I felt comfortable with.
It would be possible to run the car very close to the minimum weight limit at about 1500g if you should wish to. I've run mine at different weights between 1600g and 1750g - sometimes depending on conditions, sometimes just to see what it would do.
My fastest single lap in testing was achieved with no added weight but I wouldn't be able to hold onto it for 5 minutes like that (although I'm sure Bloomers would be able to)
I'm sure some will like it lighter, others heavier. All I have found (as with every other car I've driven in the past 4 years) is that adding weight helps me become more consistent as my reactions are not what they once were
