UMI Performance Tunnel Mounted Torque Arms
UMI Performance tunnel mounted torque arms are a proven fourth-generation setup designed to remove the front mounting point of the torque arm off of the transmission, protecting the tailshaft from damage. They also work great for transmission swaps when a clamshell torque arm is not feasible. These torque arms include instant center adjustment brackets and can be purchased with or without a front driveshaft loop. They bolt into existing floor pan holes with no drilling or welding required.

UMI Performance Boxed Weld-In Subframe Connectors
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.
