Product Details

BC Racing ER Series Coilovers (Front Only) for the 2004-2006 Pontiac GTO (VZ) feature large external reservoirs in the front and rear, separate rebound and compression adjustment, and a twin-piston design. The external reservoirs hold more oil than conventional coilovers, allowing the unit to operate for much longer before overheating. Additionally, the external reservoirs hours the secondary piston that allows for the adjustment of compression. This is the perfect coilover system for the driver who wants to fine-tune their setup using the separate 30-way rebound and compression tuning dials.

Features

  • Dual piston design (1 in reservoir, 1 in shock)
  • Full height adjustability through the shock body (not the spring)
  • 30 levels of dampening adjustment (rebound on top of shock, compression on reservoir)
  • Adjustable rear camber plates on certain applications
  • Custom spring rates available as well as Swift Spring upgrade upon request
  • 2 year warranty against manufacturer defect
  • Completely rebuildable and individual parts are available separately for purchase

Please note that not all vehicles use camber plates in the front and/or rear. Some vehicles reuse OEM upper mounts.

Reviews / Q&A

FAQs

Please read our FAQs page to find out more.

How much will BC Coilovers lower my car?

On average, Standard Drop allows about 1-2 inches of drop range below factory ride height. Extreme Low allows about 2-3 inches of drop.

Can BC Coilovers achieve factory ride height?

No. In most cases, factory ride height cannot be achieved.

What is a custom build vs off-the-shelf kit?

The stock level displayed on our website reflects the availability of standard “off-the-shelf” kits, unless noted otherwise in the product description. Selecting any custom options—such as Extreme Low, custom spring rates, Swift Spring upgrades, or top mount changes—will result in a custom-built kit. Please note: all series except the BR Series are built to order, with the exception of select popular DS Series kits that may be in stock. Also, some popular Extreme Low kits are in stock as well. To identify these, look for "Extreme Low" in the product title.

Will the struts be valved correctly?

Yes! The shocks and/or struts are always valved to match the spring rates you choose during a custom build. There is no additional cost.

Can they be rebuilt?

Yes, all BC Racing Coilovers can be rebuilt by purchasing individual replacement parts. For example, if a strut leaks, you can simply replace the shock cartridge.

Is there rush shipping available?

Rush shipping is not offered, but all in-stock kits ship very fast— most by the next day.

Customizing the coilovers in any way will delay the shipment by a few weeks on average.
