who the hell told you that??? for ultimate grip during a hard launch you need to transfer the weight to the back of the car.. the best way to transfer weight is to allow the rear end to squat and the front end to lift.. thats why succesful drag bug use stock size torsion bars and 90/10 shocks up front.. if you make the rear stiff you prevent it from squatting.. thios means no weight transfer, which in turn means reduced grip. your guy sounds like hes got his advice mixed up.
setting up a car for drag starts severely reduces its roadholding capability though.. i would not recommend the above if you intend to go round corners fast... stiff is the way to go for that. my bug hangs onto roundabouts like you wouldnt believe, but at santapod my 60ft times were laughable! i span the tyres on a freshly prepped trackall the way up to 5k rpm in 2nd gear! ...not enough weight transfer!
