Surely there has got be a cheaper, lighter and more modern LSD differential that can be used as opposed the rarer ford LSD differential???? My car is configured to receive a 7" Ford Differential until currently and with my power plant a Honda K20A Engine I need to something pretty tasty to put the power down.

Any ideas guys ???

The cosworth lsd will be about the cheapest option you can fit thats why so many kits use them. As for will it be ok with your engine ? if the diffs in good condition when you fit it it will not be an issue the k20 engine wont be anything like to much torque or power to damage it. People run lots more than you are going to without problem.

Sierra 7" with a Quaife ATB is the best choice for many.
