Why they exist
Lowering changes rear lower-control-arm angle. UMI markets relocation brackets specifically to restore/correct that angle and improve traction geometry.

Lower Control Arm Relocation Brackets
Relocation brackets correct geometry only when the bracket matches the rear housing and the chosen hole matches the actual ride height/use.
APPLICATION: Modified 1993–2002 Firebird / Formula / Trans Am rear suspension.
Rear-housing matters
UMI lists a separate relocation-bracket version specifically for Moser Engineering rear ends. Do not assume a bracket for the factory housing fits an aftermarket housing.
Bolt-in vs weld-in
Current UMI offerings include both bolt-in and weld-in designs. Installation method is part of the compatibility decision, not an afterthought.
DO NOT CHOOSE THE LOWEST HOLE BY DEFAULT
The goal is not maximum bracket drop; it is the correct control-arm geometry for the car's ride height, tire, power delivery and use. Verify interference and driveline behavior after adjustment.
FPV RULE
OBSERVE → MEASURE → ISOLATE → PROVE → REPAIR → VERIFY. Do not turn a symptom, DTC or catalog fitment label into a parts order.
