Is tekno for x2 CRT lighter or RCM conversion?
 

Need some advise I m currently racing a x2 CRT with a x1 chassis.

I m wondering if the tekno conversion kit will make it better n lighter?

Btw I m also using rcm slip diff.

They are probably very similar in weight if they are similarly equipped. Clutch and mech brakes will add a little weight, likewise the Slipperential adds a little weight as well. Batteries play a huge part in your overall weight too.
