I really want LSD installed on my car and I don't want to get a new 6MT car. Instead I contacted Quaife, they can take custom order ranging from 5~10, price would be approximately 1000USD per one custom LSD (subject to change). As I only need one LSD, I just want to know if someone is interested in getting one for their Aisin tranny. Quaife also needs one open diff inside our gearbox as reference and will return the unit
