- Excessive Weight & Poor Heat Dissipation: Leads to >15% power loss on the dyno.
- Inconsistent Cast Quality: Cracks and porosity increase warranty claims by up to 12%.
- Long Lead Times (8‑12 weeks): Delays production schedules and hurts ROI.
- Non‑Compliant Materials: Fail to meet EPA and CARB emission standards, risking penalties.
- High Unit Cost: Prices 20‑30% above market average without added value.
If any of these pain points sound familiar, you’re not alone. A recent survey of 150 US performance shops showed that 68% plan to switch suppliers within the next year.
