XRAY - Model racing cars

Hello,

How to prepare the perfect tyres for Race ?? Ive heard that one have prepare his tyres there are faster 0.2 sec of one Lap ?

And how fill the perfect diff with putty. Some peoples fill putty with silicone oil ?

Thanks for Help !

0.2 seconds a lap improvement, from tyre prep would be possible by the best drivers in the world but look at your times from start to end of a raceday you will improve from just learning the track,
I've always found it a feel thing and sometimes only cleaning the tyres means more consistency but at another track full additive for 20 mins is the way,
