I have just taken the first rounds with the new X12 - approved.
I drove only 28 rounds, but make faster laptimes than I normally do on the first drive on the day
I started - chages from the xray start set-up - with 20.000 (speedmerchant medium) in the sidetubes, gold sidesprings, 171 mm width back, active castor 7,5 degree + 1 mm shim front and 4 mm of shims on the stering block to raise the steering rod.
Way too much steering - both off and on power - and very nervous. But way more stability straight line and entering the corners - both highspeed and low speed corners.
I will on next drive try 30.000 (speedmerchant blue) in the sidetubes, black sidesprings, black centerspring and remove some of the preload of the sidesprings. I have noticed that preload on the sidesprings add steering.
Kind regards; Jens
