I play on blackwood and I am too slow...
I appointed 2/4 f/rear wing , 0 on f/r toe
my top speed is 216 with 24.20 in 1 sector...
I think with that downforce I should drive about 220...
so I need new gearbox plz help with that

Try a shorter top gear (and probably shorter other gears too)to improve acceleration down the straights.

But it's most likely you are too slow out of the previous corner, and lose time all the way down the straight.

You know, 4 kph are not much. I am on 214 at the straight and i am competative. To increase top speed, increase tire pressure.

4 kph are a lot if you are racing against evenly skilled drivers.

I have maximum tire pressure
I feel that all is in gearbox, all time I use gearbox made by vincent .
through telemetry you can see that he drive 214 with 6/7 on wings ...

Posting a replay (spr) would probably help.

nah, look at the wr. even he is driving with "only" 215...
