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, unfortunately,…

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 about handling,…

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 handling, throttle m…

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 from th…

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.…

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…

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.


The R32, R33, and R34 Skyline GT-R's used a system that looked basically identical to the traditiona…

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…
