Hi , New to this forum. I have a C43 coupe (2017) I currently have the 5 spoke AMG 18" stock rims with Bridgestone tyres on it and was thinking about upgrading to either 19" or 20 " . Not sure which size to go for and whether i will need spacers . I can go for a wider rear wheel too. Can anyone give me their view/opinion on this mod in terms of ride quality and which tyres I should look at . Also any advice an the rims themselves would also be appreciated. Thanks in advance .
