Adjustable Dampers - Are they worth it?




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.

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one.
The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would …

Bridgestone Potenza RE-71R Track Review

For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are:

1. They grip as well or better than most R comps.
2. They don't wear as quickly as R comps if driven occasionally on the street.
3. They work better in the rain than R comps.

The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine.

In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman at Tire Rack who has gone faster on RE-71R's than NT01s. In a Mustang (his own, not…

Stock Suspension S197 Mustang With Square 305/30/19's

If you've had any doubts about whether or not they will fit, fear not! You absolutely can run square 305/30/19's. I had a lot of doubts before pulling the trigger, even more so when the wheels where on the car. The tires do poke out a bit and I figured rubbing is all but guaranteed at full compression but I couldn't be happier I trusted APEX and those on here who have run it.

Here's what you need:

1. Camber plates: I have MM C/C plates and they are maxed out at -2.3 deg with the stock struts. I have been running them for years with many track days without issue.

2. 1"/25 mm spacer: I have Motorsport-tech 1" spacers and they look like high quality units. There is maybe a 1/4 inch clearance in the back so you can't go any narrower than 25 mm. http://www.motorsport-tech.com/adaptec/car/ford_s and you want Design 2.


3. Elongated studs: your best bet is to get the FPP hubs with elongated studs instead of reusing the old one. Bearings are consumables anyway so…

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track loads.…
