help Ground Control Coilover Springs FAQ
What exactly is a Ground Control Coilover system?
Ground Control Coilovers are threaded aluminum spring perches combined with racing springs designed to slide over existing factory shock absorbers. This setup allows drivers to adjust their vehicle's ride height precisely without buying a completely new set of coilovers.
Do I need to upgrade my factory shock absorbers when installing Ground Control Coilover springs?
While Ground Control kits are designed to fit over many OEM shocks, drastically lowering the car will cause factory shocks to wear out faster. Because the compressed spring perch bypasses the bump stop, enthusiasts highly recommend upgrading to aftermarket Koni or Bilstein shocks for track days.
What spring rates are available for Ground Control Coilover setups?
Ground Control utilizes standard Eibach ERS springs, which means customers can choose from a massive variety of spring rates. Enthusiasts can typically select rates ranging from 250 lbs/in for street driving up to 700+ lbs/in for dedicated track racing.
Can Ground Control Coilovers be used for autocross and track days?
Yes, these systems are incredibly popular in SCCA autocross events because they allow drivers to lower the center of gravity and perfectly corner-balance the vehicle. By upgrading the spring rates over factory setups, drivers experience significantly reduced body roll and improved handling response.
