BC Racing North America stepped up to support the SEMA builds with their BR Coilovers. BC is the manufacturer in Taiwan that builds many of today's well known JDM name coilovers. Their craftsmanship is track proven worldwide and second to none. Just holding the coilover you can feel a weight difference compared to my old Standard coilovers.
BC even offers an "Extreme Drop" option for those that want wheel tucking madness. The development team in Taiwan were able to create that with the LS430 set, so let's see how low it can truly go.
