ABT, Caractere, Rieger...they're all the most popular, but every now and then, people are gonna run into problems with fitment or something like that. Companies can make bad batches. The VW kit is typically not worth the money post purchase, but its a body kit, still an option. The kit thats probably most worth the money right now is Rieger. NA sells it for like 980 on sale, so not a bad route to go. Pick the one you think is the prettiest and save money if you cant afford it right off the bat. Its not worth buying something you dont completely like only because its the only one you could afford. Be good to your car and be happy with it.
