[quote="shawnp"] Don't get me wrong, a 4-link car is also a good option but the swingarm car will not allow for side to side movement when racing the finish line. Watch a 4-link car that has a wishbone. You can watch the scoop move side to side when ripping the throttle or even when lifting. A swingarm will not do that. For the price of cars and knowing the economy, I would think that you could hold out for a newer car. quote]
Shawn is dead on with the swingarm not allowing any side to side movement. I've had hardtails, slipjoints, 4 link, swingarm and now dual suspended car. The swingarm is the best IMO
I purchased a slipjoint car last year and had it redone, if you do get it and want to backhalf it, get ahold of Diamond Race Cars he does more backhalfs and updates then any dragster builder out there.
