Subframe connectors for a driver/cruiser, necessary to weld to floor?

I have the Hoskins really nice low profile just welded the ends in I could have gone with the bolts but decided to get them welded in night to day difference in handling . The car feels well planted under power in sweeping curved roads , larger torsion bars are another great up grade as well for a tourer, not so if your using it as a strip car.
