A comment several articles ago on quantifying ride evaluation (the ‘ass-o-meter’ as one commenter put it) lodged in my brain. It reminded me that I never expanded on the additional data acquired during this magazine test three summers ago. I’ll do that here, add a few words on the timed track testing and then give you hungry readers some enticing graphs, to balance out my verbose ramblings (wink wink!).

Apologies for the delay in getting the next article to ‘press,’ a few matters including a misbehaving back were needing my attention! Too much sitting, not enough exercise!
In the last article, we explored what influences a suspension to ‘feel sporty’ vs. actually deliver better performance. A great car rewards us with a sublime driving experience while many (most?) let us down in a various ways. As part of that article, I dove into fairly technical terms without much introduction, so I’m taking a step back to do an overview and define a few terms. Then, I’ll get into the real meat of Suspension Truth and why we’re on The Truth About Cars – more seat-of-the-pants impressions tied to juicy technical details and real-world test data like shock dyno graphs, 3-axis accelerometer results – even raw shock velocity measurements from our Aim EVO system! From here we’ll be able to give metrics for different vehicles and see what we like and what we’d like to improve.
Edit: Now with updated graph
So, what the heck does a manufacturer mean when they offer a ‘Sport Suspension’ and is it something you actually want? While I haven’t examined every version available, themes have carried through various makes/models, so what follows are safe generalizations. I even throw in a dyno chart!
Our newest segment, “Suspension Truth”, comes to us courtesy of Shaikh J Ahmad. An engineer by training, Shaikh is the owner of Fat Cat Motorsports, and a self-styled “Suspension Wizard”. Shaikh creates custom suspension components for a variety of cars, including the Mazda Miata and RX-8, the Nissan 350Z, Mini Cooper and Honda S2000. Back when I had my 1997 Miata, I ordered a set of coilovers from Shaikh, based on his reputation for creating suspension setups with a previously unheard of balance between ride and handling. The Fat Cat coilovers are one of the few products I’ve ever bought that were able to live up to the hype. Over the next few weeks, Shaikh will delve into the science of suspensions, and provide his own analysis of a number of production cars.
What’s your least memorable train ride? Simple question, right? If you’re reading this, I’m going to assume all of them. Unless a screenwriter threw you into an adventure film without your consent, it’s what we’d expect. This brings to mind a popular driving metaphor – ‘handles like it’s on rails.’ That’s our ideal in suspension tuning, to be glued to the ground and also as comfortable as possible. Easy when you’ve controlled every degree of freedom as with a train track and groomed earth beneath.
