Refined Performance USA, formerly know as Renick Performance, is grounded and founded on the idea of providing the highest quality performance parts for the Cadillac V-Series Community. 

In 2013, Cadillac announced its entrance into the Twin Turbo Performance World with the debut of their "V8" killer the CTS V-Sport. The car featured a brand new RWD Twin Turbo Engine deemed the LF3 solely unique to the Cadillac Brand. At this moment, we knew our purpose. With an extreme enthusiasm, we fully engaged our throttles with a focused intent fueled by passion— to be this Twin Turbo Platform's very first dedicated aftermarket performance company!

Shortly after this, Cadillac, then announced the forthcoming debut of their track weaponized Cadillac ATS-V! The brand soon reported that the ATS-V would as well feature an LF3 that would be modularly upgraded, and re-titled the LF4. It was at this moment that we now knew our focus was fully validated. In our minds, the outcome could only be a momentous one!

Ultimately, only three total models share this amazingly powerful high performance RWD Twin Turbo 3.6L V6 Cadillac Engine— the CTS V-Sport, the ATS-V, & the CT4-V Blackwing!

As of 2023, RP has continued to lead the way in precision LF3/4 aftermarket performance. Renowned, and celebrated for our die-hard commitment to extreme quality. We thoroughly pride ourselves on our in-house shop development, engineering & fabrication processes. Refinement & Precision has always been our strong well-built foundation. Our proven performance domination is just the logical result of our knowledge, integrity & conviction! As well, our premiere customer service has created very deep-rooted relationships with the majority of our wonderful customers, all of whom—  are the very reason that we are still rocking at full-throttle to this very day!

As the years moved forward, we expanded to add carbon fiber aero kits, blacked-out exterior paint enhancements, braking kits, lowering springs, suspension components & more! Not only for the ATS-V and CTS V-Sport but for other fantastic V-Series models such as the mighty CTS-V3! We have also broadened our parts catalog to now carry expertly chosen performance parts for many of our extended Cadillac & GM Family.
