soft loc or advanced launch question

L79, that's right, tires should be same +or-1/4lbs. If they are 2-3 lbs higher then you are hazing them long ways down track.I think they should only increase 3/4-1 1/2 bls once the cae is working properly. Measured circumference at starting line pressure should not be more than 1/4-3/8" on short tire. If you need new tires, make sure buy matched pair. From the video it looks like it is spinning most of the 330, and I think some of that is chassis. If the idea is to make the car launch better on a budget, I think I would be trying different bar settings, shock settings, maybe loosen the front some, since that doesn't cost much money.Adjustable shocks would allow you to tighten up for street use. Sometimes weight in the right place makes a car quicker and more consistent on the launch. Maybe retard 1st gear with microswitch on shifter? I sucessfully ran the same clutch you have(with some mods) before moving on to ADV. Since you already own this clutch, use it up while you sort out chassis, the maintenance on any of the centrif clutches is more intense and expensive. Then go buy ADV when you have the money. Joe.
