The eg6,ek4 and ek9 r not bad.Out of three i will chose ek4 for
road use becos it got a well weight balance chassis,but in the
track i will use ek9.Over all is depand on how u mod ur engine,play
with gear ratio,weight lighten and most important is wherever u mod
ur engine u must do a dyno test,ensure ur car is set properly.
