just one quick Question.
Is it normal that my cars weight goes down to like 600 KG when I do a chassis swap? no matter what chassis I use, the weight goes down a rediculous amount.
no its not if you want to swap the engine and turbo. That brings you to 1500 HP or so, and a weight of just 600 kg, even with 4WD the wheels are spinning all day.
Its not bad if you're going in a straight line lol. My R34 has 1,600hp, 620kg. It does 285mph on Top Gear.
But the weight depends on the chassis. If you pick a lightweight race car chassis and do all the weight reductions, you're most likely going to get below 1k kg.
