Precision Reverse Engineering
3D Laser Scanned

Having spent the last 8 years testing different laser scanning hardware and software in-house has allowed us to develop a proprietary engineering work flow that produces extremely precise fitting products. We have invested hundreds of thousands of dollars in purchasing and testing the best equipment to produce higher quality products for our loyal clients.

Designed with intent
Engineered with you in mind

It's one thing to talk about using CAD (Computer Aided Design) tools to engineer your parts, but that doesn't mean you are good at engineering parts. RSC has focused on engineering body parts in CAD since 2009, and our engineering team has over 20 years of OEM engineering experience. Each RSC product benefits from our ever growing experience from engineering large organic shapes such as complete replacement bumpers for Lamborghinis to highly intricate load baring products like replacement door handles.

Exceptional Quality
Premium Materials and Workmanship

We start with making better molds by using premium tools manufactured from Carbon Fiber or Aluminum to ensure logevity and consistency in each part. We use the finest pre-impregnated carbon fiber to provide a maximal strength to weight ratio. Our craftsman ensure the weave is consistent in direction and free from defects. We cure our parts in state of the art autoclaves despite the added cost. Finally each part is painted 5-10 times with a deep clear coat providing outstanding depth and clarity that will last for years to come

The rear is all most people see of a C8 and this makes it look great.

The rear diffuser looks awesome and really pops in bright sunlight. Fit was perfect and it arrived well packaged and in perfect condition.

Defuser Impression.

Happy again. Something this size, and complexity I didn't know what to expect. After inspection I didn't find any flaws. It was installed today 09.22.2021. Installation went smoothly. All holes lined up. The defuser game with a bag of fasteners. You can't beat the beautify, Pricey, but you get what you pay for. Carbon flash on a 100K car, I don't think so.

RSC Rear Diffuser adds the finishing touch

The rear diffuser adds a very classy touch. The fit is perfect and the style is subtle yet bold. I use RSC for all my carbon accessories on the C8.
