I´ve just bought one for my Focus 2.0 turbo because the standart mtx75 diff died after some 1/4 mile runs with toyo R888.

And was hoping to get enough traction without these semislicks, on the street/strip with the FRS box

I have 292 bhp and 430 nm (317 ft/lb),
and expect around 310 -320 bhp and 450 - 460 nm (330 - 340 ft/lb) as the limit my car i gonna get. So if you mean it can handle this im happy
