Motorsport AOS on MY 2002 ?

[ChrisZang]

Going this year to the track on R-comps I want to be ready for high g-forces in long, fast left hand turns (Thunderhill turn 2)

So to avoid hydro-lock due to an overloaded AOS I wanted to switch to a Motorsport AOS following the instructions here:
Will a Motorsports AOS work on a Boxster? - RennTech.org Forums

I quickly figured out that this is too tall an order for me, so I took the car to my very trusted mechanic and after having a look at my AOS he told me that the Motorsport-AOS from Porsche only works for MY 2003 and higher.

So is there a solution for MY 2002?

Thanks
