Road///Race FTW for most Lancer-specific mods

It's important to note that used Road Race parts aren't always available on ebay (especially when you have the money to buy it) and the generic stuff is hit or miss and may not have much of a real warranty. I say buy it from them directly so you get a warranty and you know everything is still functional.
