There is a bit of misinformation about the whole issue Devin, this started way back in v3 when we moved onto v4. Certain people thought that by simply lowering the chassis model (ingame mesh) it would alter your trucks handling. The fact is you have to modify the node/beam or values in the truck files (be is shocks2 or flexbody lines). Like I said above, if you have ever looked at Box5's node/beam that we still use, the shock node are less then half of the proper length they need to be (so like maybe 12-13" of suspension travel as a rough estimate). Most trucks today run 26"/26" or 26"/30". The lack of travel is even more compounded by improperly placed shock body and shaft models.
Yes it is a game and yes people should be able to setup their trucks how they like, at the same time, what is the point of making proper handling trucks when people will lower their trucks, reduce inbound and outbound travel so their trucks is easier to race? (*cough*SSRS Grave Digger 20*cough*) I almost wish we had proper breakables because then with all of this would be moot since trucks would break constantly from the lack of suspension travel.
