This came out of my car as I've gone with a Modena torque biasing diff instead. This is just too aggressive for me on tarmac, it locks up very quickly and while it might suit some driving styles, it's not for me. Been advised it would suit a gravel setup more.
It was fitted by the previous owner and has only been used for 500 miles, some of which were competitive at sprint events but mostly driving to and from venues. Barely used as confirmed by the garage that removed it.
Can post at buyers expense, happy to arrange or collection no problem.
Looking for PS650.
Thanks
