93-02 UMI Boxed Subframe Connectors (Weld-In)


Model Number: 2000
UMI Performance

Minimize chassis flex and increase performance capabilities on your 93-02 GM F-Body with boxed style weld-in subframe connectors from UMI Performance. Subframe connectors are a must chassis upgrade when racing and hard driving habits are present. They 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 better weight transfer and improved traction when launching. When strength is a concern, square tubing has greater torsion resistance over tubular designs. Will work with all aftermarket exhaust systems and does not effect ground clearance. This weld-in style requires no bolts to tighten ever and less chance of flex compared to bolt-in types.


  • Built using 2.000? x 2.000? x 0.120? Mild Steel Square Tubing
  • CNC Machined 0.188? Thick Mild Steel Mounting Points
  • Uses Control Arm Mounting Point for Increased Strength
  • Precision MIG Welded Construction
  • Brilliant Durable Powder Coat Finish (Red or Black)
  • Will not fit convertibles

Weld-in only, installs in approximately 2 hours, all necessary hardware and detailed installation instructions included.

    this was on my list for a while and now i know why they should have been the first thing done… they are NOT for people that cant WORK with metal, but after the install the improvement was amazing… no body rool the whole car is super stiff, handles great now n looks good, also dont be stupid buy only weld in and NEVER round tube. but overall this is the best thing done to date…

    FINALLY had these installed over the weekend…definite difference in handling. only downside is expect to pay 2 hours labor for install 🙁 …unless you already know how to weld, than good for you! ;P i think these are the perfect balance between strength and weight…the 3 points are to heavy and pricey, tubular sfc’s arent as strong as boxed (in my opinion) …and dont be a fool and get bolt on because you dont want to pay for welding!
