I agree with you, however, spending an extra $2600 or so to get all the components and pay for fabrication is a huge expense. I'm tortured over this decision.fladoans said:To get any benefit from Mini tubbing the leaf springs, must be moved in offset) and the shocks mounted inboard of the leaf springs. So if you do all this, then yes you must run a narrowed gas tank. I am using the DSE mini tubbing kit (not installed yest - but I have it) and will probably use their gas tank, or one from ROck Valley. The 275 tires look okay, but IMO nothigg beats real meats out back. DSE claims you can run 335, but I am probably only going with 315.
