California’s D3 Cadillac offers many upgrades for nearly all Cadillac models, from carbon fiber door sills to Borla exhaust systems. Unsurprisingly, part of D3’s inventory includes upgraded suspension components for the ATS, CTS, outgoing CTS-V, and CTS Vsport. Amongst these upgrades are D3 coil springs developed and produced in house. D3 has also teamed up with JRI Shocks to produce a very impressive coilover system that features over 1000 points of adjustment, allowing a driver to really fine tune the handling of their Cadillac.
D3 has already released lowering springs for the current-generation Cadillac CTS, but has not yet released a full coilover system. Prices for the springs vary from $389.00 to $429.00 depending on the model, and whether or not the vehicle is equipped with magnetic suspension. Height drop is dependent on the model as well, though the lowest seems to be a 1.5 inch drop for the front and rear, while the least amount of drop is 3/4 of an inch in the front and 1 inch in the rear.
JRI manufactures the coilover system designed by both JRI and D3. When engineering these systems, the two companies had the following points in mind:
- Reducing breakaway seal friction or stiction
- Reducing internal gas spring rate and rod force
- Reducing friction in running and side loaded conditions
- Increasing dynamic response in higher frequencies
- Reducing hysteresis
There’s also a setup for the ’09-’15 CTS-V, and it comes with a price tag of just under $5,000. That’s a bit of coin, but still cheaper than pads and rotors for a Z06 Corvette, and from what we can tell they appear to be well worth it for any driver hoping to track their second-gen CTS-V competitively.
