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

You don’t need any of Them, just keep driving!

A car needs to hook and have some good power before it will need frame connectors. If you have a mild 360 you won’t have too much power, and if radial T/A tires you won’t have much traction on the street.

Vega? WTH?

Scamps and Darts are much better cars that that junk. With a mild small block and street radials it’s not needed. How many thousands of A body mopars are out there without them?

I wholeheartedly disagree, even mild street going cars will benefit from subframe connectors. The may not be "mandatory", but the improvements they offer can be noticed even with a mild street car.

I know that because before I installed my subframe connectors I was just running a tired 318/auto and 225/60/15's. After I installed them I went to a 400+ hp 340 with a 4 speed. The chassis was stiffer, despite the upgrade in power, then it was before.

And you have to consider what the factory design was intended for. The chassis wasn't even engineered for radial tires, they were designed and left the factory with bias ply's. So while I may poke fun at the "hockey puck" hard BFG T/A radials, they're still a BIG improvement over the factory tires. Which means more traction and more flex than what the factory intended.

And the other thing people overlook is this, the factory doesn't as a rule do what's "best". Sure, there are great engineers involved, but there are also bean counters involved. In most cases, you can count on the factory to do the cheapest thing that they think will sell and won't run afoul of any regulations. So just because the factory sent these cars out without subframe connectors doesn't mean they aren't better with them installed. Remember, these things were supposed to last ten years and then get tossed.
