Hey Guys when buying the type r with 19"rages it crossed my mind whether it would impact performance or not with having a bigger rolling radius and I couldn't find any info on it! Incase anyone wondered the same see vid attached as you can see the rages actually give a slight edge over stock :D

I've looked in a few places and cant find any info about the size of the stock speakers in my car ( 2011 type s 1.4 ) just wondering if anybody here could help me out and tell me the right size/depth of the speakers so i can look into buying new ones, thanks
