when i press brake and thorttle same time its makes nothing and i want burnout :||||||| can i do burnout without brake ? :SS

That's because you cant press brake and accelerator at same time with your combined axis pedals!!! It's no use to make another topic if the problem is showed in first one.

i want to know can i do burnout without brake ?

Two ways:
1) Hold clutch (put it on button, since no 3rd pedal)
Full throttle. Let go off clutch.

2) Put gearbox in N. Full throttle. Shift into 1st

The XRG car from demo does not have that much power but still possible to do donuts this way.

it not makes ( why ? (( (sorry for my english)

Depends on the definition of burnout.

Short 1st gear and can wiggle around and smoke tires while doing donuts.

another demo xrt guy, gotta love it.

Maybe its because your setup. Try adjusting your tyre pressure to the max then put your gear to n, rev up then gear 1.

Demo XRT isn't super suspicious. If you have an older version of LFS (before FBM), the XRT was demo content.

take this set its for burnout only
