what lsd is inside the dinan diff?
manufacturer? setup? ramps (power/coast)? number and coating of clutches?
i am experimenting with lsds here as well. i currently have os giken, drexler (bmw ms m3gt4 unit), titan and zf for my m3. of course it will take a while to have them all tested in detail.
the first os giken setup (standard spec-s) completely failed. now i will get some different parts from japan to hopefully get it to work properly.
finding and setting up the perfect lsd for someones driving style is an exciting thing. :-)
