Big power and competitive corners can bend your unibody vehicle like a pretzel! Build a better foundation for power with a set of weld-in subframe connectors from Summit Racing Equipment.

Big power and competitive corners can bend your unibody vehicle like a pretzel! Build a better foundation for power with a set of weld-in subframe connectors from Summit Racing Equipment.
Back in the 1960s and 1970s, cars like Mustangs, Novas, Camaros, Firebirds, and Challengers featured unibody construction, which was great for everyday driving. However, as hot rodders and racers started adding power, they found that the subframes would flex under serious load, resulting in poor handling, crooked launches, and even metal fatigue. Weld-in subframe connectors were developed to tie the subframes together, resulting in less flex and more traction!

Bolt-on subframe connectors are great for weekend warriors who may want to remove the connectors later, but for dedicated race vehicles with serious horsepower, weld-in subframe connectors are the way to go. They keep your tires firmly planted and your chassis straight, so all that power you’re making goes right to the pavement.
