At Dežru Suspension, we get a lot of questions about coilovers, suspension design, and which setup is best for different types of driving. Here are answers to the most common questions enthusiasts ask—so you can choose the right system for your build.
General Coilover Questions
Q: What are coilovers and why are they better than lowering springs?
A: Coilovers replace both the spring and damper with a matched suspension system. Unlike lowering springs that often overwork stock shocks, coilovers provide height adjustability, optimized travel, and tuned damping for real performance gains. [Learn more → Lowering Springs vs Coilovers]
Q: Are coilovers good for daily driving?
A: Yes—when engineered correctly. Dežru coilovers use Bilstein digressive pistons and HyperCoils springs to balance comfort with control. Systems like the Spec-S or Spec-RS are ideal for street use with the option of weekend track performance.
Q: How long do coilovers last?
A: With proper maintenance, premium coilovers like Dežru’s can last as long as OEM suspension. Our systems use globally sourced components (Denmark, Japan, England, USA) and are assembled in the U.S. to strict quality standards.
Street & Track Use
Q: Which coilovers are best for daily driving with occasional track days?
A: The Spec-S is ideal if you want comfort during the week and sharper handling on weekends. For added adjustability, the Spec-RS offers 1-way rebound tuning and optional external reservoirs for more serious track use.
Q: What’s the difference between 1-way and 3-way adjustable coilovers?
A: 1-way controls rebound only—perfect for simple tuning between street and track. 3-way adds low-speed and high-speed compression adjustments, allowing for full motorsport-level tuning. [Learn more → Spec-R 3-Way Coilovers]
Off-Road Use
Q: Do coilovers work for off-road vehicles?
A: Absolutely. The Spec-G coilover was designed as a 2” lift suspension system with inverted long-travel dampers and bypass piston valving. Unlike spacer lifts, Spec-G increases articulation, droop, and stability on rough terrain.
Q: Are lifted coilovers comfortable on the street?
A: Yes. The Spec-G was designed for the everyday driver and casual off-roader. It delivers comfort during commutes while offering stability and clearance when trails get rough.
Track & Competition Use
Q: Which coilovers are best for dedicated track cars?
A: The Spec-R coilover is built for track enthusiasts who demand maximum tuning control. With 3-way external reservoir adjustment and Bilstein COB digressive pistons, it provides professional-level suspension tuning.
Q: Why is digressive valving preferred for performance driving?
A: Digressive valving gives stability and chassis control at low piston speeds (braking, cornering, transitions) while allowing compliance at high speeds (curbs, bumps). This balance makes it superior for both track and spirited street use.
Installation & Setup
Q: Do I need a professional to install coilovers?
A: While experienced enthusiasts can install coilovers at home, we recommend professional installation to ensure proper preload, alignment, and torque specs. For maximum performance, follow up with a performance alignment and corner balance.
Q: How should I break in new coilovers?
A: Drive 300–500 miles of mixed daily driving to allow seals, springs, and oil to settle. Then recheck ride height, alignment, and corner balance. This ensures your suspension is dialed in for long-term consistency.
