I have 2 slightly older cars in my stable and both are having similar issues. We have a 2001 MR2 Spyder with 72k miles, and a 2002 Honda CRV with 230k miles. The CRV recently got new shocks and springs, new lower front control arms and front compliance bushings, and new front ball joints. While it now rides a little bit better, it still crashes over bumps and just feels like an old worn suspension even with all the new components. (Read More…)
I own a 2000 Audi A6 2.7T that I bought 3 years ago. It has been a surprisingly good vehicle to me – comfortable and fast. I even track it on occasion with no complaints. It’s been fairly reliable; the most major issues were having the ABS controller rebuilt and replacing the valve cover gaskets myself, which were not a big deal. As long as nothing catastrophic happens, I plan to keep the car for many more years. (Read More…)
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!).
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.
Hey, it coulda happened!

I love the column and I’m a daily TTAC reader, though I rarely comment. We have been a Panther household since the mid nineties, and have had great luck with our vehicles thus far. My parents had two ex-Budget rental Town Cars, a white ’93 with blue interior, and a medium willow green ’96 with that greyish-beige. I had a pearlescent silver ’91 in high school with black interior and a black canvas top (I added ’02 Cartier wheels , P71 front springs, and a dual exhaust with turbo mufflers). All were zero-problem vehicles. Which brings us to our current Town Car, an ’07 Signature Limited, fresh out of warranty, which is also an ex-rental, but I do not know which company.
I have a 2006 Mazda5 GT which has blown it’s second rear shock in less than 87,000 km. My question is whether I should just replace it with yet another Mazda part, or whether I should go aftermarket and replace both rear ones at the same time. My concern with this option is whether or not the ride quality will be maintained. I do not want to end up with a harsh ride with an aftermarket part. Does anyone have any suggestions? What is a good brand for shocks? Does anyone have any experience with the Mazda5 or have a suggestion for shocks? I am also tempted to just rid of the car altogether :( This would be the fifth repair related to the suspension in three years of ownership.
