UMI Performance boxed weld-in subframe connectors are necessary chassis upgrades when racing and hard driving habits are present. UMI Performance boxed weld-in subframe connectors greatly improve your car's handling ability, while reducing T-top squeaks, dash rattles, and quarter-panel flexing. Subframe connectors essentially tie the front and rear steel subframes together, resulting in a stiffened and strengthened chassis, allowing for better weight transfer and improved traction when launching. When strength is a concern, square tubing has greater torsion resistance over tubular designs. They will work with all aftermarket exhaust systems and will not affect ground clearance. Their weld-in style requires no bolts to tighten and offer less chance of flex when compared with bolt-in types.
