Starting at low prices, AutoBuffy stocks multiple alignment camber/toe kits from top OE-quality brands. These kits provide adjustable bolts, eccentric bolts, shims, or cam plates that let a technician correct wheel angle to manufacturer spec. When camber or toe drifts out of range — from worn bushings, bent components, or a hard impact — tires wear unevenly and the vehicle pulls, costing you tires and safety.
The right kit depends on how far out of spec your angles are and whether the Buick Regal Sportback has a factory adjustment provision. Some vehicles have no OEM camber or toe adjustment at all, requiring an aftermarket kit to create that range; others have adjustment but need extended-range hardware after a lift, lowering, or collision repair. Match the kit type to your correction need before buying.
| Option | Best for | What you get |
|---|---|---|
| Eccentric/Cam Bolt Kit | Vehicles with no factory camber adjustment; quickest correction method | Replacement bolts with off-center cams that rotate to dial in camber or toe within a fixed range |
| Shim Kit | Rear axle or strut-mount applications needing small, precise angle corrections | Precision-ground metal or composite shims inserted at the mounting point to shift angle incrementally |
| Adjustable Control Arm or Lateral Link Kit | Lifted or lowered Buick Regal Sportbacks needing large correction range; track or performance use | Fully adjustable arms or links that replace fixed OEM pieces, offering broad camber and toe sweep |
| Camber Plate / Strut-Top Kit | Front strut suspensions on lowered Buick Regal Sportbacks; adds top-mount adjustment not present from the factory | Billet or stamped upper strut mounts with slotted or multi-position holes for camber and sometimes caster tuning |
Raise and safely support the Buick Regal Sportback, remove the wheel, and replace the stock bolt or mounting hardware with the new cam bolt, shim, or adjustable component. Set the adjustment to the midpoint of its range initially, torque all fasteners to the manufacturer's specification range listed in your service manual, and reinstall the wheel. Always follow up with a professional four-wheel alignment — home installation sets the hardware, but a laser or optical alignment rack is required to dial in the exact target angles.
