Purchased th BR series RH.. Th coilovers at first glance, seemed pretty strong n sturdy & of decent build..! Installation was done by a professional (so, while unable to comment on th process or ease of install), th coilovers did feel real sweet n steady!! Initial ride height immediately after installation was considerably higher than where me previous coilovers sat, and yet it still felt as sturdy! Regardless, another inch drop seems inevitable =) … Transaction with BC Racing was real easy, & I would likely purchase from again.. defs happy wif me purchase.. (..oh, & steer clear of XYZ and DGR suspension coilover kits; have used both, these are waayy so much better👍!! )
