DSC Sport Controller: 1800 Mile Impression

I have just spent 1800 miles on this controller over the past week since I received it and installed it. I’ve driven through various terrains from well paved highways to unpaved twisty mountain roads to cobble stone streets.

I was skeptical at first when I plugged it in. Initially, I was expecting to get some placebo/fake validation on the $1200 I spent on a plastic box in the trunk. I drove on the road with the bumps. It felt exactly the same. I drove in the neighborhood with speed humps. It felt no different. but about 30 min later, I was driving back home and reached a low speed right hand turn that has a road sign suggested to take at 20mph, where I took it a bit faster normally everyday. It was right then where I felt the difference. It was this low speed turn where I noticed the planted-ness of the car (not a real word, I know). This makes me think that the statement of the oil in the dampers needed to “warm up” holds true. Any pogo feeling or skipping that I think some owners have experienced seem to be gone.

Although the suspension felt good and I was feeling a bit better on selling some early crypto gains to get this electronic suspension tuning box, I wasn’t 100% convinced. I figured I’d notice more with more miles. The rest of the 1800 miles I’ve spent included a road trip from S. Florida to North Carolina with majority of it on normal mode.

I’ve driven in the streets of the oldest city in the U.S. where you wouldn’t expect the most wonderful streets. The cobble stone was still rough but better than I would have expected, but I really can’t say DSC did it’s job since I was going about 15mph.

Rough highways with uneven pavement was as expected. I finally got some more fun with on/off ramps because S. FL is devoid of any fun cloverleaf interchanges. I enjoyed these much more and felt more confident at higher speeds than the on small ones I get to drive at 60mph max.

Paved and unpaved mountain roads of North Carolina were fun. Transitions from left to right on curves, switchbacks felt great with much grip. The unpaved roads of the Cataloochee valley on normal mode seemed fine. I truly can not imagine how it would have been with out the active damping.

Some overall notes and things I also noticed:
I’m one of those folks who didn’t complain about the ride quality for DDing, but I later noticed I’ve been blessed with commutes with very decent roads.

I’ve taken the RS on a road trip before and managed to wake my wife up on the rough parts of the highway or construction. This time, she slept through continuously through similar conditions until I had to brake more suddenly when we reached traffic and even then she apologized thinking she woke up from her snoring.

Although it is agreed that the stock sport suspension is unusable in most conditions, I like it as a gimmick laugh mode and was scared I would loose that with the DSC installed. I have switched back and forth to see if I would get that sensation and noticed on some roads it was no longer the silly party trick and was more improved when at higher speeds >50mph. Although, I was driving on SR 202 East to Jacksonville Beach and noticed the rough bumpy road in normal mode and decided to see if sport suspension would bring back that laughable suspension feeling back, it did. I guess on some roads, the stock dampers and DSC just can’t handle it, not that Sport would have been the mode of choice for the road anyhow.

Thinking back to one of my original road trips, I did feel a bit that the stock suspension felt over damped but was able to brush it off despite the complaints from the wife. This time I didn’t notice it as much while driving on some bumpy highways.

I can’t wait to get this on autocross. Unfortunately this might make my car faster, but not make me a better driver. I’m thinking that this controller will punish me much less for bad braking, racing lines and upsetting the car’s balance around corners. It feels like there will be more grip for me in the future.

After owning the RS and over damping my adjustable Konis in previous cars, I don’t think I could get another sports car without active dampers. I really like knowing that these dampers can still be tuned. I can’t imagine what this controller can do when tuned to the Tractive dampers with better tolerances (or any aftermarket adaptive dampers) vs the stock Tenneco ones.

I’m running 18×8 OZ Racing Omnia on Yokohama ADVAN A13C 240/35
Stock suspension at 21k miles
I’m comparing my stock suspension experience with 2 track days, and a full season of Autocross on bumpy parking lots that corvettes fear.

TLDR;
I was skeptical at first with the DSC controller and after 1800 miles later on various roads, I’m very happy with it and think it’s a great first suspension mod for those lazy/inept/with fat wallets to do on their stock RS to improve ride quality and more grip on less than ideal road surfaces.
