Suspension parts always choose carefully! You pay the price which a suspension is worth and B14 is worth its price: Knowhow from motorsport, but for all of us with TÜV certification for the street.
To buy cheap is totally inappropriate. Save up your money a little bit longer and don`t get angry on poor quality of a no-name-product. The trouble with a poor-quality-suspension takes more time than the joy of making a snatch!
