Hah! Well I'd hope so Carbon ones are 1.5kg front and 0.4 rear (just inserts). Anyone know actual figures before I order some?
Ok so weighed passenger side this morning. Quite surprised actually! Mine had been stripped of sound deadening etc already but still weighs 3.9kg, so these will save 2.4kg a side and it's up front weight too. With lexan and motors removed etc that should be another 3 ish kg per side. Then if you were to swap to frp doors...another 10+ kg per side.
MC Racing in France or APMotorsport in the UK. I've bought mine from France as APM are just a reseller for loads of stuff.
