how has the reliability been for your os giken differential after a few years of drifting? any expensive maintenance done that require changing out the clutches in it?
I also remember a DIY you posted on the ABLS switch. When I drift with the OE VLSD, sometimes I would see the ebrake light flashes, while the ebrake was not being used. Is this an issue with the ABS? I did not hit the brake during those donuts or figure 8. but as soon as the ebrake light flashed, my car started understeering and I am thinking it may be the VLSD unlocking the wheels due to heat.
