JRZ is highly regarded in motorsport for its innovative approach to suspension technology, offering coilover lines tailored to both aggressive track use and refined street comfort. Two of their popular product tiers, the JRZ 11 Series and the JRZ 12 Series, each serve a distinct audience. Below is a breakdown of how they differ in adjustability, typical applications, and overall driving experience.
JRZ 11 Series: Straightforward Performance
Key Points
-
Single-Adjustable Design
The 11 Series generally features a single external adjuster that influences both rebound and compression simultaneously. This setup helps racers and enthusiasts dial in their vehicle’s handling without juggling separate dials. -
User-Friendly Tuning
Fewer knobs mean simpler changes at the track—ideal for those still learning to optimize suspension or seeking an easier approach to fine-tuning. -
Suitable for Dual-Purpose Cars
Whether you daily drive your sports car or occasionally hit the track, the single-adjuster format often strikes a sweet spot between comfort and improved cornering.
Who It’s For
If you want a bump in performance with minimal fuss, the 11 Series suits drivers who seek better body control and improved grip without diving into granular suspension tweaks.
JRZ 12 Series: More Advanced Adjustability
Key Points
-
Double-Adjustable Dampers
The 12 Series separates rebound from compression, giving more granular control over how the suspension behaves under varied conditions—corner entry, mid-corner bumps, and exit acceleration. -
Enhanced Tuning Precision
Splitting adjustments allows you to fine-tune the ride for specific tracks or driving styles. This can be especially valuable if you frequently chase lap times or face different course layouts. -
Track-Focused Edge
While it’s still possible to use the 12 Series on a daily-driven car, the ability to dial in stiffer or softer settings independently appeals strongly to club racers and pro-level users seeking a competitive edge.
Who It’s For
Enthusiasts and racers who crave in-depth adjustability, plan to attend multiple track events, or want the maximum potential from their coilovers will find the 12 Series a compelling choice.
Deciding Between the JRZ 11 and 12 Series
- Adjustability Needs
-
- 11 Series: Single-adjuster simplicity.
- 12 Series: Separate rebound and compression for more precise customization.
- Driving Style
-
- 11 Series: Balanced for street and occasional track use.
- 12 Series: More focused on performance tuning, ideal if you often refine setup for each event.
- Budget and Maintenance
-
- The 11 Series might come in at a slightly lower price point, with simpler maintenance due to fewer moving parts.
- The 12 Series can cost more, but offers a higher ceiling for improvement, especially in competition settings.
Final Thoughts
JRZ 11 Series coilovers deliver a user-friendly approach to upgrading suspension for improved handling and a smoother ride compared to stock, while JRZ 12 Series coilovers cater to those wanting to meticulously tailor their damper settings for each corner or condition on the track. Both lines benefit from JRZ’s renowned build quality and motorsport pedigree, so your decision rests on how hands-on you plan to be when tuning—and just how far you want to push your car’s limits.
