UMI Performance LSX poly engine mounts bridge the gap between factory GM rubber and UMI solid engine-side mounts. These mounts are a great choice for builders wanting a high performance mounting solution without committing to race-oriented solid units. Dimensions are based on GM 22179268, as used in the 1998-2002 GM F-Body and as seen in the UMI '99 Camaro with Pace Performance LS3. Recommended for use with: UMI 2320, 2321, 2330 and factory K members, as well as 2406 and 2410 LS swap mounts used in other platforms. Additional notes: * LSX poly engine mounts are a great choice for high performance street driven vehicles * Direct replacement for GM factory rubber engine mount 22179268 * Designed to place the engine in stock location * 3/16 in. laser-cut steel construction using US steel * Gloss black powdercoat * High-quality flanged fasteners included (torque to 45 lbs.-ft.) * Re-use factory thru bolt (not included) * Notch indicates top of mount * If solid mounts are desired, use UMI 2323 and 2328 * Polyurethane mounts balance performance and quietness

Reinforce your car's chassis with these UMI Performance driveshaft tunnel braces. These braces replace your weaker, stamped factory brace that is able to twist with the car, creating excess force in unwanted areas. UMI Performance uses full-machined endplates that bolt into your factory locations, joined by rectangular tubing that is fully MIG-welded for added strength. Topping off these braces is either a red or black powdercoated finish that shields them from the elements. Protect your car from the twisting effect caused by weak factory parts and replace them with these UMI Performance driveshaft tunnel braces.

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.
