i found the BEST set-up for polished wood so far (in the way of tyres)
on the front;
used minipins with white inserts
on the rear;
BRAND NEW mini pins with white inserts
the grip goes after about 5-7 mins of driving, but for the heat, or even better the final it is great
it gets a bit / a lot of understeer, but the back end is like it is on rails (i couldnt slide the back end with a WOT and 19T motor, but i could after the 5-7 mins)
