Adjustable Dampers - Are they worth it?

Image
By



Adjustable dampers are far from perfect. If they were, a car like the Camaro ZL1 would be Mercedes S-Class (or equivalent) comfortable on potholes, Camaro Z/28 (or equivalent) stiff on smooth tracks and infinitely adjustable in-between on mid corner bumps, road imperfections, speed bumps, etc. GM's magnetic shocks are excellent but, while they are one of, if not the best adjustable dampers available in any mainstream car, they're still a huge compromise between ultimate comfort and ultimate chassis control, you just give up less in performance and less in comfort compared to fixed dampers but get added cost and complexity in return.

The added cost and complexity aren't the only issues, either. Ironically, adjustable dampers put a huge roadblock on adjustability if you ever decide to modify the suspension. Every modern car now has stability control and adjustable dampers would have to be connected to and monitored by the stability control system. Buying aftermarket dampers would upset the stability control system since the signals from the stock electronic dampers would be missing. I know some people don't like stability control but they can save a very bad situation and can even be useful on the track by putting a nice safety net while someone is learning.

Moreover, a stability control system warning light will probably come on so if you bring your car to the dealer for service, it'll probably cause warranty issues. There may be a handheld tuner to disable the warning light and let the stability control system function properly, but then you get into issues with flashing the car's ECM (although that may not be an issue if you intend to modify the stock engine tune anyway). Basically, it's a huge hassle.




Are they worth it? Absolutely, but only if the car is appropriate. I don't think they are worth it on cars that can be considered track toys. Cars that are expected to be modified a lot for autocross and track days such as Focus ST's or RS's, Mustang GT's, a Camaro SS's, etc. But I would like to have adjustable dampers on a car like a Cadillac CTS-V for example, a car that I would track if I owned, expect to be immensely capable but should still be completely civilized in everyday driving. Now if the adjustable shocks are manually adjustable like the Koni Sports (Koni Yellows), they are a perfect fit for track toys.

2004 Audi TT 3.2 Quattro DSG Track Review

By
Before getting into this, I have to confess something... I had never driven an Audi TT before. Not until this one, anyway. But that hasn't stopped me from forming an opinion about it from the comforts of my own couch while reading and watching reviews online. After all, if you've never done that, do you even know what the point of the internet is? Now, we all interpret reviews differently. Call it confirmation bias if you will, but if you like a car, you'll read a review and look at the positives as what makes the car great and the negatives are but a few quibbles you have to live with. If you don't like a car, the positives are a few things the manufacturer got right while screwing up everything else. It's a bit harsh to put the TT in the latter category, but that's where it ended up for me... I never took the TT seriously. The problem with the TT for me isn't that it's a Golf underneath, per se. There is nothing wrong with a performance car sharing a...

Falken Azenis RT615k+ Street and Track Review

By
Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax  set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f...

Why an Open Differential Doesn't Work on Track

By
C7 Corvette Grand Sport... doing a burnout with a proper diff - Graham MacNeil  © I wrote a tech post comparing various open and limited slip diffs for a comparison and I found that a lot of people were asking questions. To simplify and make it easier to read, I decide to break them up for a future tech article about handling. Make sure to stay tuned for two posts on limited slip diffs this week!. WHY DO YOU EVEN NEED A DIFFERENTIAL? A differential's job is to allow two wheels on the same axle (or two axles in a 4WD drivetrain) to spin at different speeds so a car could smoothly go around a corner. Why do the wheels need to spin at different speeds? Each wheel on a car has to travel a different path to reach the end of the turn. You can see that for yourself every time you drive on snow covered roads or muddy trails.

GTR vs Evo X vs STI: which has the best AWD system?

By
A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky...
