Buick Regal 2009-2017.
The coilover guide.
Shop the coiloversMatch the Regal's year range and chassis equipment before choosing suspension. Include driven wheels, front struts and any electronic dampers in the check.
One Regal generation, different chassis equipment.
BC Racing lists two front-wheel-drive applications for this Regal generation: ZH-02 for 2009-2013 and ZH-03 for 2014-2017. Start with the build details and original market, then identify the suspension fitted to the car. A registration year or Regal badge leaves some of that work unresolved.
The GS, cars with electronic damping and the later all-wheel-drive models need particular attention. Send the existing strut and damper details with the wheel sizes and intended use before agreeing a kit.
Buick introduced the New Regal in China in December 2008. The 2011 US model brought the four-door saloon to another market, with CXL and CXL Turbo specifications. Those regional names and model years help explain why the car's build details belong alongside the kit's year range.
The 2011 US brochure describes front MacPherson struts and an independent four-link rear suspension. Its optional Interactive Drive Control System on the CXL Turbo changes electronic damping alongside other vehicle responses. Identify that equipment on the actual car before discussing a passive replacement.
Buick updated the styling and equipment for 2014. The Canadian brochure distinguishes the front-wheel-drive car's four-link rear suspension from the all-wheel-drive model's H-arm rear arrangement. It also identifies HiPerStrut applications and the GS's Interactive Drive Control System. An exterior facelift photograph cannot settle those hardware differences.
The BC listings split at 2014 within this generation. Treat those references as separate checks, including engine, market and factory suspension. Older Regals and the later Sportback or TourX need their own application evidence.
Start with your Regal 2009-2017.
Confirm the chassis, year and existing suspension before choosing your setup.
2009-2013: check the early FWD specification
ZH-02 is BC's earlier Regal FWD entry. Include the original market, build year and engine, plus photographs of the front struts and any damper connectors. The US CXL Turbo could have electronic damping; the year range alone does not identify it.
Check my earlier Regal
2014-2017: identify the facelift FWD car
ZH-03 is the later FWD entry. Give the build details and fitted front-strut design, and say whether the car has electronic damping or eAssist. Confirm the mounting arrangement and supplied parts against that specification before choosing the later reference.
Check my facelift Regal
GS or electronic damping: identify the hardware
Include the GS specification, driven wheels and photographs of the fitted struts, dampers and connectors. Buick's GS material describes HiPerStrut and Interactive Drive Control. Agree the replacement hardware and treatment of the existing controls and warnings before ordering a passive kit.
Discuss my Regal GS or electronic dampers
AWD, eAssist or previous suspension changes?
Identify the drivetrain and engine equipment, then list previous spring, damper or mounting changes. Both BC application entries specify FWD, so they do not establish an AWD installation. Have an eAssist or converted car checked for its exact hardware and requirements as well.
Discuss my Regal's equipment and changesWhat do you want
from the car?
Road miles, circuit weekends or a car built around the lap. Start with how you drive.
Agree a height that leaves room for everyday roads.
Read the buying advice
Describe the surfaces, entrances and passengers the car needs to accommodate. Confirm the correct ZH reference and the springs and mounting parts first, then discuss usable travel and clearance with the fitter. The BR adjuster changes compression and rebound together. Use the instructions for the supplied assemblies to establish the starting settings.
- Confirm the year and chassis equipment
- Inspect retained mounts and worn parts
- Keep working travel and tyre clearance
Bring the tyre sizes and a realistic setup plan.
Read the buying advice
Discuss how often the car will visit a circuit and which tyres it will use there. Check the suspension application before choosing springs or settings. Record adjustments so changes can be assessed one at a time, and include the final alignment in the fitting plan.
- Include both road and circuit tyres
- Agree spring and damping settings
- Record the height and alignment
Choose the suspension with the car's builder.
Read the buying advice
Give the builder the tyre, wheel and changed-hardware details, together with any event requirements. Have the complete spring and damper specification agreed around that car and its available travel. The two road-model application headings do not establish race eligibility, an AWD conversion or a GS installation. Bespoke spring or hardware requests need a separate discussion.
- List changed suspension hardware
- Agree the complete spring package
- Include fitting and setup work
The rear spring has its own seat.
On a standard 2011 US Regal 2.0 Turbo GNC factory rear layout, the rear spring and damper are mounted separately.
Component layout only. Mounts, dimensions and adjusters vary by kit.The factory service illustration for the 2011 US Regal 2.0 Turbo GNC rear suspension shows the spring and its isolators at a control-arm seat, separate from the damper. Buick's later AWD H-arm arrangement needs its own check.
For the chosen BR kit, confirm the supplied rear spring, height-adjustment parts and damper arrangement. Use its exact instructions to set the spring seat and damper length where adjustment is provided. Have the fitter check retained parts, working travel and spring retention through the required movement before agreeing the running height.
Read about running height and spring preload
Check the existing hardware before setting height.
Have the fitter identify the front struts and inspect the mounts, joints and bushes the installation will retain. Include previous suspension changes and any electronic damper equipment in the order discussion. Agree which parts the BR RN specification supplies and which original components it needs.
Wheel width, offset and spacers affect the clearance check. Bring the tyre sizes for both axles and check the body and suspension through the movement the car will use. Set the intended running height before the final alignment and keep the measurements with the service record.
Front struts and retained mounts
Photograph the fitted assemblies and give the car's original equipment details. The listings describe BR RN with no front top mount and rubber at the rear; confirm the supplied and retained components for the exact car before fitting.
Electronic damping and GS equipment
Identify any Interactive Drive Control or electronic dampers, including previous removal or conversions. Agree the hardware, controls and any warning-handling work for the proposed passive installation. A GS badge alone does not settle the strut or drivetrain specification.
Wheels, tyres and working travel
Give the width and offset of both wheel sets, tyre sizes and spacer thickness. Check clearance through steering and suspension movement, with enough travel for the roads or circuits the car will use.
Drivetrain and final alignment
Both current BC application entries specify FWD. Keep an AWD enquiry separate, and identify eAssist or other engine equipment. After the agreed installation and running height are settled, have the alignment checked and record the settings.

Compare the controls and hardware included in each range.
The current Regal selection has BR entries BCR-ZH-02 for 2009-2013 and BCR-ZH-03 for 2014-2017. BC's application list identifies both as FWD with BR RN availability. The shop specifications describe no front top mount, rubber at the rear and default rates of 7 kg/mm front and 6 kg/mm rear; confirm that package for the car before ordering. BR combines compression and rebound adjustment. Exact struts, retained parts and electronic damping remain application checks, including GS and eAssist equipment.

Questions about Buick Regal 2009-2017 coilovers.
Check the details before choosing your kit.
Which BC references are listed for this Regal generation?
ZH-02 covers the manufacturer's 2009-2013 Regal FWD entry, and ZH-03 its 2014-2017 FWD entry. The current shop listings are BR specifications. Check the build details, original market and fitted equipment before selecting either reference.
Do these listings confirm fitment for an AWD Regal?
Both BC application entries specify front-wheel drive. Buick's 2014 Canadian brochure describes a different H-arm rear arrangement on the AWD car. Send its exact details for a separate application enquiry; a shared year range does not establish compatibility.
What should I check on a Regal GS?
Include the build year, market, driven wheels and existing front-strut design. Buick's GS material identifies HiPerStrut and Interactive Drive Control equipment. Have the mounting parts and damping controls checked for the exact car before agreeing a replacement.
Can I replace the factory electronic dampers with these BR kits?
Have the complete installation confirmed first. The 2011 US brochure describes optional electronic damping with CXL Turbo Interactive Drive Control, and later GS material also identifies a control system. Agree the mechanical parts and how the existing electronics and warnings will be handled; the kit heading does not answer those questions.
Is the factory rear spring separate from its damper?
The identified 2011 US Regal 2.0 Turbo GNC factory service illustration shows a separate spring at the control-arm seat and a damper alongside it. Confirm the actual car and replacement assembly; that example does not define every regional model or the later AWD suspension.
What does the listed RN specification say about top mounts?
The shop entries describe BR RN as no front top mount and rubber at the rear. Ask which original components the selected package retains and what new parts it supplies for the car. Have retained mounts and bearings inspected before fitting.
Which spring rates do the listings describe?
Both shop specifications describe 7 kg/mm front and 6 kg/mm rear. Confirm the supplied rates and spring arrangement with the selected reference. A different rate or a developed circuit setup needs an enquiry rather than an assumed selectable option.
Does the BR adjuster change rebound only?
BC describes BR as combined compression and rebound adjustment. Use the instructions for the exact supplied kit to establish its settings and adjustment procedure. Record changes and assess them one at a time.
What information is useful for an eAssist Regal?
Give the engine and eAssist details, build year and market, with photographs of the current suspension. Buick's 2014 Canadian brochure identifies an eAssist FWD specification, but a FWD kit heading does not separately approve its hardware or requirements. Have those checked before ordering.
Can I use this guide for an older Regal or a 2018 Sportback?
Those cars need separate application evidence. These BC entries concern the 2009-2013 and 2014-2017 year ranges within the saloon generation. Older Regals, the later Sportback and TourX are outside that scope.
Let’s talk suspension.
