Does the car go straight on the launch



Thats a difficult question to answer.. most of the time it will go straight, but every once in awhile, it will want to veer off to the right..

Anti Roll Bar in the rear.



I was told that anti roll bars do not work on ladder bar set ups..


I would scale it first but if you think its goes
straight most of the time it should be close...if
the car flexes (which its doing), then yes a anti
roll will correct it but the anti roll is covering
up flex... if it wasnt flexing you wouldnt need a
anti roll(the ladder bars would hold it level)
