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.

Tin Soldier Racecars Low Prep 4-Link Kits

Tin Soldier Racecars Low Prep 4-link kits have taken what they have learned from some of the fastest stock suspension and 4-link small tire cars and combined them into one universal kit. The shorter upper bar allows the car to separate quickly on the launch like a stock suspension car, while keeping the versatility and strength of a traditional 4-link. It's truly the best of both worlds. The chassis brackets are laser cut from 1/4 in. thick plate and feature 1/2 in. staggered holes for all the adjustment you need whether on a radial or slick. The chassis brackets are notched on bottom for 1 5/8 in. tube and have through holes for a 1 5/8 in. tube on top (12 in. spread between). Each bracket has ProJack tabs incorporated into the bottom of the brackets. The axle housing brackets are designed around 275/315 or 28/29 in. tall tires, but still work well with larger tires. They are laser cut from 1/4 in. thick plate and feature 1/2 in. staggered holes for all the adjustment you need whether on a radial or slick. The axle housing brackets are made for 3.5 in. axle tubes and feature 6 in. of shock adjustment in 3/4 in. increments, while including ProJack tabs incorporated into the bottom of the brackets. Steel shock mounts are included. The bars are made from chromoly tube and feature 3/4 in. HD chromoly rod ends with zinc plated jam nuts. The bungs feature a hex adjuster and are constructed from chromoly. Tin Soldier Racecars Low Prep 4-link kits were originally designed for drag radial cars, but after much testing we have found that they really work well on no-prep to moderate prep on any small tire, slick, or radial. If you're looking to increase your traction and lower ETs these kits are for you.
