The only one's I'm aware of for an S53/S54 tranny from a 5s-fe are Kaaz and TRD. Those are quite pricey...any other brands?

Hey



those are probably the lowest prices for LSD's


got one for the eclipse and it was 850 from Kaaz

so is there any for the ST?

If there is, its probably gonna say its for the 4agze or something to that extent, but it'll probably work

To my knowledge there aren't any others that are made specifically for that tranny but several others can be made to wrok. If you're really serious and want to spend the money, have a Quaife made for it. They are the best all purpose limited slips available hands down. If you don't have much money and don't expect your car to launch like a maniac (although still much better than stock) then check out Phantom Grip. They've quoted me some very low numbers in the past. They don't have an application for the ST so you have to take apart the tranny, pull the diff and send it off to them. If I remember right its $275 + shipping of the diff 2 ways. The quaife will probably be $1100 just to purchase the carrier and anywhere from a few hundred, to a thousand to have it machined and adapted to the ST tranny.
