Race car build - weight loss

[Jerry Can]

Can anyone give me some specific examples of how much weight they were able to remove from a hot hatch/saloon type car whilst turning it into a race car?

I'm specifically interested in a post 2002 car that would have had more modern secondary safety items like door bars and air bags as well as A/c sound deadening. Is 150kg possible?

After gutting the interior etc or after that stage? Easy to lose well over that amount starting from a road car. Don't forget you'll be adding a fair bit of weight back in with a roll cage but 150kg should be no problem. My 1998 Puma is nearly that under standard and didn't have half the bells and whistles of the new (2009) car I'm building. I swear the seats alone weighed 150kg between them with the electric and bags in them.

Sound deadening is always the shocker. I didn't weigh with the new car but with the Puma it was nearly 30kg.

From standard road car to the point of adding back in a cage. Yes I could imagine the seats are heavy.

It is a power to weight formula, 145bhp/tonne. Road car is 1080kg and power 138hp. Not far off, I reckon I need it down to about 950 exc me, and a small power hike to get to the number.

thanks for the replies, food for thought
