cool mod idea
 

what about sticky tires, i'm sure that a 3.8 engine with a high power gear ratio could go up a wall.

There are "soft" tires not sticky. and a 3.8 would not go up a wall. An Inline maybe, but never a wall. Also Torque is a big issue here and a 3.8 doesn't have much torque unlike some other motors.

ok, the mod idea was making sticky tires

in order for a BIt to stick to a wall, you would need tires that stick like some glue. But with tires like that, your car would not go anywhere even on a flat floor. SPEED is right there simply not enough torque on a 3.8 to climb anywhere.

Probably you need a Spider-Bit.;)
