RE: Best upgrades for manace .21
I think they are both 2.2, so you should be able to use the same tyres. Best setup is probably to drop the suspension by removing the spacers because it is a bit too high to handle well being a stadium truck, plus there are no anti-roll bars fitted. I wouldn't bother with the Venom road tyres from Schumacher; I have a pair and they are rubbish. Best to try another on-road tyre, or even a wheel & tyre set meant for the Menace GTR.
