Re: Heavy Ralley Wheels
If it were a drag car this would be a huge gain..
I have always been told for every 100 lbs of weight you remove from your car your 1/4 mile times can improve by as much as one tenth of a second. Every 1lb of rotational weight is good for 4lbs of static weight depending on the weight of the wheel X the force of the launch/acceleration.
Another thing to consider is even though you lost weight overall you gained diameter and more weight is concentrated at the outer diameter than before. In other words you likely gained rotational mass by changing to a larger diameter wheel/tire combo. It will take more power to turn the wheel/tire combo than a smaller diameter wheel/tire combo of the same weight.
Its a give/take situation.
