23kg difference. That's the weight of my youngest brother (minus 5kg). Can definitely feel it.
Weight reduction I couldn't feel: Foglight removal, shaved aerial, lightened headlamps etc.
I reckon about 20kg is where I start to feel it. It may be my imagination though, but I swear I can.
And no, I take them to Nandos coz I'm so baller I make minimum wage c*nts lol.
