The Hidden Solution to Your Most Frustrating Automotive Challenges
Have you ever walked away from a restoration project because that one crucial part was simply nowhere to be found? Or watched your racing ambitions stall because your competitor’s design gives them a persistent edge? According to a recent J.D. Power study, over 40% of classic car restoration projects are abandoned due to parts availability issues alone.
These seemingly insurmountable obstacles – the discontinued components, the performance limitations, the skyrocketing costs of OEM parts – have left countless automotive enthusiasts, manufacturers, and race teams in a state of perpetual frustration.
What many don’t realize is that there’s a sophisticated engineering approach that addresses these exact challenges. At RDS, we’ve helped hundreds of automotive professionals overcome their most persistent roadblocks through advanced reverse engineering techniques.
In this comprehensive guide, we’ll reveal the seven most common automotive problems that reverse engineering solves, backed by real-world examples from our engineering team’s experience. These aren’t theoretical solutions – they’re proven methodologies we apply daily in our work with automotive manufacturers, restoration specialists, and performance shops.
Problem #1: Discontinued or Obsolete Parts
Perhaps the most widespread challenge in the automotive world is the disappearance of critical components from the supply chain.
Why This Happens:
- Manufacturers typically discontinue parts 7-10 years after model production ends
- Tooling for older components is often scrapped to make way for newer production
- Smaller production runs become economically unfeasible for manufacturers
- Company bankruptcies or acquisitions can orphan entire vehicle lineages
- Original suppliers may go out of business or change business models
According to the Automotive Parts Remanufacturers Association (APRA), over 500,000 unique automotive components go out of production annually in North America alone.
How Reverse Engineering Solves It:
Through a systematic process, reverse engineering creates accurate reproductions of discontinued parts:
- 3D Scanning: Capturing precise geometry of the original component
- CAD Modeling: Creating a digital recreation with identical specifications
- Material Analysis: Identifying original materials and suitable alternatives
- Manufacturing Method Selection: Determining optimal production approach
- Production: Fabricating exact replicas using modern manufacturing techniques
At RDS, we recently helped a restoration shop recreate the die-cast aluminum vent window frames for a 1950s luxury sedan. The original manufacturer had been out of business for decades, and the remaining NOS parts were selling for over $2,000 each – when they could be found at all.
Using our structured light scanner, we captured the exact geometry of a damaged original, reconstructed it in CAD, and manufactured replacements that were dimensionally identical to factory specifications. The new components cost less than 25% of the market price for originals and are now available to other restorers facing the same challenge.

- Material Evaluation: Assessing suitability of original materials
- Design Modification: Strengthening vulnerable areas while maintaining fitment
- Validation Testing: Confirming improvements through simulated and real-world testing
At RDS, we worked with a fleet maintenance provider facing frequent failures of a transmission component across multiple vehicles. Through CT scanning and metallurgical analysis, we discovered:
- An internal corner radius that created a stress concentration point
- Inadequate case hardening depth for the applied loads
- Porosity in the original casting affecting structural integrity
Our redesigned component featured:
- Optimized geometry with improved stress distribution
- Enhanced material specification with deeper case hardening
- Modified manufacturing process to eliminate porosity
The result was a 300% improvement in service life while maintaining complete compatibility with the original system – saving the fleet operator over $120,000 annually in maintenance costs.
Problem #4: Rising OEM Part Costs
As vehicles age, the cost of original replacement parts often increases dramatically, sometimes reaching prohibitive levels.
Economic Factors at Work:
- Decreasing production volumes drive up unit costs
- Manufacturer pricing strategies for legacy components
- Inventory carrying costs passed to consumers
- Reduced competition as alternate suppliers exit market
- Currency fluctuations affecting imported components
The Automotive Aftermarket Suppliers Association (AASA) has documented average price increases of 8-12% annually for components in the later stages of their lifecycle.
How Reverse Engineering Creates Affordability:
Cost-effective alternatives emerge through targeted engineering:
