Frequently Asked Questions
Is this a full kit?
Yes. BC Racing coilover kits include suspension units for all four corners of the vehicle. Some applications require the original top mounts or rear springs to be reused, so the selected variation should be checked carefully before purchase.
Are the coilovers preset?
BC Racing kits are generally supplied at a moderate lowered height, with spring preload already set and damping positioned at a sensible starting point. Final adjustments can be made during or after installation.
Are end-links included?
End-links are supplied where the anti-roll bar attaches to the damper and the revised mounting position requires a shorter link. Original end-links can generally be retained where replacements are not included.
Can the vehicle be used on track?
BC Racing coilovers are developed with performance use in mind. Standard specifications are suitable for road and occasional track driving, while alternative spring and damper setups may be available for more focused track vehicles.
Installation
Professional fitting is recommended, followed by a full alignment once the suspension has settled. Available from Paramount Performance, vehicle tuning and performance specialists since 1986.
