I don’t have sources for the exact episode/page Vegeta says it, but the dragon ball wiki tells me that Vegeta says the effect of the suits is greater than Bulma’s gravity machine.
Weighted clothing are clothing fitted with built-in weights to make them heavier than ordinary clothes. Weighted clothes are used by several warriors throughout the series. Goku uses weights such as a black undershirt and later a dark blue undershirt and dark blue boots at the end of Dragon Ball...

The gravity machine currently goes up to 500 times Earth’s gravity.
Vegeta weighs 123 pounds.
123x500=61,500 pounds or 30.75
The suits are at least heavier than that
