Frequently Asked Questions:
What are the advantages of C4 Corvette Coilover Conversions vs. Factory Leaf Springs?
The primary advantage of C4 Corvette coilovers is independent corner tuning. While the factory transverse composite leaf spring is lightweight, it "couples" the left and right sides of the suspension. Coilovers allow for:
-
True Independent Suspension: Better stability over mid-corner bumps.
-
Ride Height Adjustment: Precise control without the need for longer bolts or "lowering wedges." Must be aware of shock travel when lowering your Vette as there are limited shock lengths available for the C4 chassis.
-
Spring Rate Customization: The ability to easily swap springs for specific track or street applications.
What are the drawbacks of switching to coilovers on an 84-96 Corvette?
The main drawback is suspension travel management. C4 Corvette coilovers offer a shorter total stroke than the factory setup. When lowering a C4 Vette on coilovers, you must be hyper-aware of shock travel to prevent bottoming out, which can damage the shock valving or the chassis mounting points.
Are aftermarket composite springs better than C4 coilovers for street use?
Aftermarket composite springs (like those offered by Van Steel) are ideal for owners who want to maintain the original GM design philosophy while restoring ride height and not altering ride quality.
-
Pros: Factory style installation, similar to OE ride quality for Base model or Z51 suspension setups.
-
Cons: They offer limited ride height adjustability compared to coilovers and cannot be "corner balanced" with the same level of precision.
How do I prevent bottoming out a lowered C4 Corvette on coilovers?
To ensure longevity and ride quality when lowering a C4, you must:
-
Measure Static Ride Height: Ensure the shock has enough "compression travel" (bump) left. Use the o-ring at the top of the body of the shock to check for travel during initial test drive. Also see Van Steel's Ride Height Guide.
-
Use Aftermarket Bump Stops: To provide a progressive end to the suspension stroke.
-
Consult Van Steel Tech Support: We provide specific shock lengths tailored to your desired ride height to ensure you don't run out of travel.
