Hi Ian
Yes, losi oil.
I considered changing the wheelbase too... but didn't get around to trying it !!
I too am interested in the long versus sort front link characteristics.
I do though think that the main setup aid, that has not being discussed that much in this thread is WEIGHT ! I bought some 1.5mm brass plate and cut a piece to sit exactly along the chassis / battery area. It's around 92g so as the losi lipo is around 30g lighter I'm running an extra 62g under the cells in real terms, then the 50g on the rear too.
Loving the car though, if I'd had a clear run, or 2 yesterday I would have put it in the A, as it was my heat was tricky with lots of 'Jam' cars I had to lap a number of times that only needed to catch me out once, then it destroyed that run, still put it in the B though
