Built-To-Order Suspension Kits Available at APEX

We know there's no one-size-fits-all for coilover kits. We also know that there's a difference between simply lowering your car, and actually improving its performance in a meaningful way. It is crucial that any coilover kit is built around a quality damper, which is why all of our kits are built around the JRZ RS Line. However, we all use our cars differently, so we offer the ability to customize a coilover kit using race-proven components to meet your specific goals and budget. Best of all, you can get it all from one place.

Why buy from APEX? It's simple. We use better springs and camber plates, we custom-build kits to your specs, and best of all, everything is in stock and ready to ship from our Livermore, CA warehouse. Not to mention, we've priced our complete JRZ coilover kits below others that are selling them with lesser quality components.

JRZ Suspension Engineering calls on over 60 years of experience in development and production of motorsport dampers. With numerous factors like track surfaces, weather conditions and tire compounds, the adjustability of JRZ dampers ensures you can utilize your car's full potential at all extreme ends of the spectrum.

Ground Control has been building world-class street, track, and full road race suspension setups since the 1980s. They have designed and built setups for hundreds of different chassis and applications. From no-compromise racing camber plates to refined, comfortable street plates, Ground Control's engineering and attention to detail makes them our camber plate of choice for any street or race application.

We chose Hyperco springs mainly because of their near-perfect (within 2-4%) linear rates. They're more resistant to bowing than most other brands of spring, and because of their highly developed design, the springs are able to maintain their original free length and rate throughout a near-infinite operational life.

Very interesting, great business concept and idea you guys are doing. Might really consider this over a premade setup from other big companies.

Here are a couple photos of the kits that were produced specifically for us in our last group buy:

[jns_e85]

Since there is another group buy on these available, I am considering the JRZ RS TWO and have a couple questions:

1. On the deal configuration, it lists a race camber plate option for Z4s and not Z4Ms. Is there a race camber plate offered for the Z4M in this deal?

2. The setup I am considering would include race plates and Level 1 spring rates since my vehicle is used daily and for autocross, as well as an occasional HPDE. How frequent would the dampers need to be rebuilt? (6,000ish street miles per year, ~ 15 autocrosses, and 4 HPDEs)

Jns,

In regards to the race camber plates, you will need to select the "Z4 Race Plates" option in the configurator. The race camber plate design for the Z4M and Non-M does not differ which is why there is only one single Race plate option for the Z4 chassis.

The level 1 setup is ideal for a dual duty car that is not running any aero or slick tires. JRZ recommends a rebuild interval of 24,000km (roughly 15,000 miles) to "maintain peak performance for racing applications". We see no issue stretching a rebuild to over this 15k interval.

With your current projections of how often you drive your Z4, you would easily be able to get 3 years (!) of use out of the dampers before we would recommend rebuilding them.

It's all in the details. Our helper spring adapters are designed to minimize stack height at all costs. Using a recessed mounting pad adds less than 1/4" to the overall height of the setup, while precisely matching the diameters of both springs and not allowing any play.
