Unsprung mass - Wikipedia, the free encyclopedia View attachment 4687

That may help - basically think about a push bike - the wheels are what you need to move with your own legs via the pedals/chain and if they are light it's a damn sight easier
Yea I had a read at that, it's not unsprung weight but rotational. From what I've read...

"Rotation weight loss is great as your car will rev easier, not necessarily gaining any horsepower but it will be more efficiently transferred to the ground with less weight having to be initially displaced.

The trade-off here is that you'll loose mass that transfers into motion, F=MA and when you subtract any amount of mass your overall force will be lower and thus initial torque onset will be lower until in motion."


Any ideas how much the stock cat back system weighs? I've heard its pretty heavy....

Mine was one balled and has since gone - but when I picked up the two Milltek boxes they felt loads lighter so sorry no real data

Someone might have a old one to weigh

I'll stick up stock Mani/Cat and a few other bits tonight

Oof @ the glass roof :/

Any idea how much more it weighs than just the standard metal roof?

Also, anyone got the weights for the standard 17" MCS alloys and/or a runflat tyre?
