Anybody actually used this kit? has it lasted or is this such a new product nobody has used it? Any rattles afterwords or anything? Im needing a front end rebuild on my A4 and I really would rather not shell out 1000$ for control arms on a car I paid 300$ for. This is like, the cheapest option for control arms and it seems like an amazing deal and not made in China from what im reading, Made in Turkey. Any opinion on them would be great.
