Ok, gone are the airbox and everything associated with it. I have a length of flyweight hose to a foam sock, the spare wheel, all turbo and engine heat shields except the one on the rear bulkhead, the turbo fan and all brackets (it didnt blow enough air to the intercooler to make up for the weight), standard exhaust replaced with ART straight through, engine cover and hinges,all the metal in the rear seats and all rear belts, all padding and bolts behind the rear seat and most of the padding from un der the centre console, rear speakers, both front belts replaced with harnesses (a bit lighter!), the metal brackets that hold the corners of the front bumper, standard battery replaced with teeny weeny red top race battery and a few other odds and sods of clips and brackets from the engine bay. If you are used to looking at a standard GTA engine bay mine looks very uncluttered.....possibly naked
Ive kept the stereo for the odd trip to work and for psych up music when I'm queueing for the start of events. (Kings of Leon being the best in my opinion!). I'd imagine the stereo and speakers probably weigh 3-4kgs....but I love my music!!!
