The BMW Z4 and Toyota GR Supra share a front lower control arm design with a factory bushing that leaves little room to correct camber after lowering or track alignment changes. This Whiteline KCA497 front lower control arm bushing kit uses a dual offset design to add positive camber adjustment range, helping optimize tire contact and improve overall handling.

Whiteline designs and manufactures suspension components engineered to sharpen handling while preserving daily drivability. Their caster and camber correction kits, control arms, and bushing sets use proprietary synthetic elastomers and precision engineered geometry to correct factory suspension compliance and unlock more consistent, predictable handling.
The KCA497 is a Whiteline front lower control arm bushing kit for the BMW Z4 and Toyota GR Supra that adds camber adjustment range using a dual offset synthetic elastomer design.
Why would I need extra front camber adjustment?Lowering the vehicle or making significant alignment changes for track use can push camber outside the factory adjustment range, and this kit provides the range needed to correct it.
How is this different from the KCA495?The KCA497 focuses on camber correction at the front lower control arm, while the KCA495 is a separate kit that increases caster and negative camber gain at the front radius arm.
Do I need an alignment after installing this kit?Yes, a full front end alignment is recommended after installation since the kit is designed to change camber angle.
Will this kit help with tire wear?Yes, correcting camber back within a proper alignment specification helps distribute tire wear more evenly across the tread.
Can I install this kit in my home garage?Yes, most installers with basic hand tools and jack stands can complete this bushing swap, though a proper alignment afterward requires shop equipment.
Will this kit work with lowering springs or coilovers?Yes, this kit is commonly installed alongside lowering springs or coilovers to correct the camber shift that comes with a lower ride height.
Is this kit front or rear specific?This kit is for the front lower control arm only and does not include any rear suspension components.
