What is the best mod to cut down lap times?

You've got some money saved. You have been thinking about modifying your car to make it quicker and now is the time to go shopping. If you're not sure what to get, the good news is that with track days and interest in lapping becoming more popular, you can easily find good resources online. Better tires are usually recommended as the best place to start and I couldn't agree more. If you want to improve the specs of your car, tires are definitely the best place to start. If you want to go faster, though, save your money.. Last weekend, I headed to the track for Atlantic Sports Car Club (ASCC) Time Attack #2, my first timed event. I've only been going to non-timed, lapping events for the past few years but I've wanted to start going to timed events for a while to make sure I'm moving in the right direction. The event included 5 sessions - a practice session and 4 hot sessions. I was planning on using my GoPro camera to film all timed sessions but, unfortuna

Mazda MX-5 (Miata) Defy Convention

Defy Convention.. that's how Mazda sums this ad. The ad starts out with a group of cars, all of which are convertibles faster than an MX-5 (Miata), lined up to set up for a drag race. The Mazda, an uninvited guest according to the ad, shows up as they're getting ready to launch and just before they take off, it starts "raining" (later in the ad you learn that a water truck starts dumping water on the track). As soon as it starts raining, they all "race" to put their top up before they take off and the Mazda gets the top up the quickest, takes off and finishes the 1/4 mile first. I have no problem with a good play on words for ads. I love creative advertising. In this case, "the world's fastest convertible" is the one that takes the least amount of time to put the top up. The problem I have with the ad is the selling message. The Miata has never been about features. It has never been luxury, speed or power. It is isn't even abou

2014 Corvette Stingray gets 30 mpg, rated at 29 mpg EPA highway!

How does it get 30 mpg, yet it's rated at "only" 29 mpg on the highway? Well, you may remember from an earlier post -  Corvette Stingray makes 460 hp!  - that one of the new engine technologies for the Corvette is Active Fuel Management (AFM) which saves fuel by shutting down half of the engine's cylinders under light load driving conditions. Many enthusiasts, myself included, were not too sure what to think about the AFM technology from a performance perspective. Will throttle response be delayed or dull to prevent firing up all 8 cylinders? Will the auto transmission shifts be slower or hunt for a higher gear on the highway to activate AFM? These are among the questions that were worrying me but, as it turns out, enthusiasts need not worry. At the live reveal of the Corvette earlier this year -  The Stingray is back!  - Chevy announced that the car will be available with a 5-mode Driver Mode Select (DMS) feature which varies attributes like active

Discount Tire Direct - A Canadian Order That's Tough to Beat

Last December, I bought light weight 18" wheels to replace the heavier 19" stock wheels. I had been planning on doing it this summer but I was forced to do it at the time (find out why here ). I always have several automotive parts website bookmarked. Whenever I want to buy something, I open up the related sites (in this case Tire Rack, Discount Tire Direct, 1010Tires, etc.) and decide (mostly) based on prices and shipping charges, the latter are often a lot for orders shipping from the US to Canada. I ended up on Discount Tire Direct  (DTD) because they had the best prices and they were very helpful over the phone. I was happy to find good service but was very disappointed that Discount Tire had the best prices.. let me explain. If you go to the home page of 1010Tires , you'll see "We are Canadian, Eh! All Canadian orders are shipping from Canada, Pay no duties, Pay no brokerage fees, etc." A clear selling message that if you're in Canada and you buy

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

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

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

Limited Slip Differential Types Compared

BMW M2 equipped with an eLSD - BMW © A few weeks ago, I posted about traditional clutch-type limited slip diffs (LSD's) and how they work. You can read about those in the previous post: How Limited Slip Diffs Make You Faster on Track . But as you might know or have learned from reading the article, they aren't without their faults, which means engineers are always working to get around those limitations. You may not be surprised to learn that something like the Ferrari 488 GTB doesn't use a traditional limited slip diff, but it's not limited to super cars, far from it. Cars like the Golf GTI, the Civic Type R, various Mustangs, Corvettes, and BMW M cars, and even the Lexus RC F and GS F, all avoid a traditional limited slip diff in favour of one of these technologies. To keep things simple, I'll focus on two wheel drive vehicles. The vast (vast) majority of principles apply to all and 4 wheel drive vehicles, but there are some subtle differences that I'll

2004 Audi TT 3.2 Quattro DSG Track Review

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
