Very confused

Your friend obviously has no clue how to tune or how to drive or possibly both.

A decent JRSC set-up just feels like a larger displacement motor, there is no lag, which tends to lead to people breaking the tires insanely loose off the line at the strip and running shitty times with decent traps.

Lag is a blessing in disguise for FWD

why is that. So out of no where ur front wheels start spinning out of control??

With proper traction (slicks) that doesnt happen.

i have been saying this since i got my setup,my shit ant spooled till 5600 rpm and i wouldent have it any other way

This comin from the pro lets not forget.
