I need to understand what interest there is for titanium springs for the Gen V ACR dampers (only ACR at this time). These are not off-the-shelf springs, they are custom titanium springs designed for the ACR dampers. The springs are optimized for the travel and load of the ACR with the intent to reduce weight, increase response, maximize reliability, and make them as cost effective as possible.
The benefits of titanium springs, beyond the optimized design, are an improved frequency response (quicker to respond over bumps, etc.), longer fatigue life than stressed steel springs, maintained extended length over time (steel can settle a bit reducing overall length with time), and maintaining spring rate regardless of temperature. These will be more consistent over time for ride height and spring rate.
Of course titanium does not corrode but I have yet to decide if these will be powder coated or not. The downside of powdercoating is the additional weight, the upside is it is easier to tell if there is significant rock/impact damage to the spring. The springs are not fragile but significant rock impacts could cause an issue so inspection should be a part of maintenance.
On to the details… the springs will be ~1” shorter than stock as part of the design optimization. This length is gained back by moving the adjusters on the shock back to the location required to achieve the desired ride height. All this means is that you ultimately don’t have the ability to raise the car to monster truck levels that are many inches higher than factory delivered ride height. This also means that you could potentially lower the car beyond what you could do with the stock springs. The bottom line is, beyond the initial adjustment on install, the shorter length will not be a factor at all in the real world, adjustability well above and below street/track heights are still available.
Weight savings will be ~2.2 lbs per corner in the rear and ~1.5 lbs per corner in the front. Cost will be ~$2,875 per set. I need to get about 10 people to justify the investment and get this pricing. It is likely this could be a one-and-done deal unless there is a ton of interest. We would be looking at January delivery.
Thanks,
Doug
