Hey chase, I have an 07 aveo5 and if your looking for mods there is not really much, I've dropped an aem cold air intake and had to make my own exhaust system cause there is no aftermarket ones, I also have a set of 16" rims with low profile tread on mine, but as for the lowering springs the is at least 3 different companies that make some like h&r and eibach I do believe. There is a thread about nodding mk2 and mk3 golf coilovers on here somewhere and I think there is also a front brake kit you can buy from powerstop. There is also a company called ultra racing for strut tower bars and such but honestly just look around and keep digging you will find more I'm sure of it to get some ideas of the direction you wanna take your aveo and welcome to the forum
