In regards to that Glanza its awsome but that price is way to cheap for the year etc that should be close on £6k but its worth a view as that would be one of my dream Glanza's!! To really get the most out of the handling you would also need to get a anti-lift kit for the front and a rear anti-roll bar as they arent on the car standard Check Toby's ToyTuning store on this site for EVERYTHING you could ever need As for brakes there are lots of things you can do it just depends how far your budget can stretch The main thing in the weight loss plan is obviously rear seats, interior trim, and sound deadening. but then you could also get lightweight wheels and CF body panels etc More technical info wuill be along when other guys post Hope that helps bud ;)
