If you are launching hard with a DSM / Eclipse W4A33 AWD Automatic or the rare AWD 3000GT GTO SR Automatic then you need these.
These are standard ratio.
Professional installation recommended, note these are straight cut gears and have a distinctive whine you can often here on our youtube videos @ youtube.com/rvengeperformancetransmissions
These often ship directly from Liberty Gear and there may be a delay before your order ships, particularly for international orders.
