we didn't get the LSD on our UK rx7's is it a good upgrade? i.e. is it worth importing one from the US or should i just find something in the UK that may be better?

thanks

They are a clutch type and lock up nicely. I'm happy with them in my cars, I'm glad I swapped them in. The GSL diffs are better than teh GSL-SE diffs so if you are going to go through the trouble of shipping it over there you should look for a GSL...
Did Miata's have LSD over in the UK because the early miata diffs will swap in assuming you have the 84/85 large axle housing...

 

yeah they are good diffs but good luck finding a gsl diff with the smaller axle housing.

 

mine has the larger GSL-SE diff but not LSD, you say the Miata fits is that the MX5?

idk about the miata diff working but if you have the larger axles then the FC non turbo diff should be good on it

hell KAAZ even makes **** that will fit that car im jealous

click me for diff options

 

nice so a non turbo diff will fit the GSL-SE housing with out modifiying and they are LSD

the carrier from an FC will NOT fit an FB.

 

I was under the impression that the non turbo FC diffs are interchangable with the 84/85 FB housing. They are both 7"

 

thats what im interested in doing

 

i was too.

 

I posted this link in your other thread but I'll post it here too, its a miata site, but according to the article the 84-88 NA diffs are all basically the same and you can interchange them....
