Limited Slip Differentials - The Basics

I'm finishing up a comparison post (link to introduction: Intro: Focus RS vs Golf R vs WRX STI vs Evo X ) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much. By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the

Car and Driver Lightning Lap 2016 - A Closer Look

Where did the time go? I unfortunately missed last year's feature. I did intend to post about it this year but haven't had the chance and it's already time for this year's feature. I thought I'd get this one done first and then go back to last year's (hopefully). The full article for this year's LL is here:  Car and Driver - Lightning Lap 201 6 . As always, my car picks aren't necessarily very quick or slow. They simply did much better or much worse than I excepted them to.  The Highs BMW M2 - 3:01.9 : Last year, a BMW M4 did 3:00.7. 1.2 seconds is all that separate the iconic M4 (an M3 coupe, really.. doesn't that sound better?) from this M2. And that one had the dual clutch transmission and carbon ceramic brakes. Opt for the manual, and you could very well be neck and neck. But you save *ahem* about $30,000 in the process, a little more if you're in Canada. That's what you need to get an M4 with the competition package, dual

2016 Camaro SS vs 2016 Mustang GT - Road Test

If you've come here for a new instrument head-to-head test, I'm afraid you'll be disappointed. Although, for the sake of those who do want numbers, here they are from the most recent Car and Driver comparison test: 2016 Camaro SS 2016 Mustang GT 0-30 mph 1.6 s 1.7 s 0-60 mph 3.9 s 4.4 s 0-100 mph 8.9 s 10.5 s 1/4 mile 12.3 s @ 116 mph 13.0 s @ 112 mph braking 70-0 mph 147 ft 157 ft 300-ft dia.skidpad 0.98 g 0.94 g 610-ft slalom 43.9 mph 43.3 mph For some reason, Car and Driver tested an 8-speed auto Camaro and a 6-speed manual Mustang, so figure you'll lose a tenth or two with a manual; the gap is still clear. The new Camaro SS out accelerates, out brakes, and out grips the new (now almost two years old) Mustang. And I'm not here to tell you otherwise. If you're reading this, chances are, you'v

Mods and Update: Focus RS vs Golf R vs WRX STI vs Evo X

Earlier this month, I introduced the cars that we'll be testing in a comparison. The cars included a Focus RS, a Mk7 Golf R, a 4th gen WRX STI and an Evo X. Unfortunately, the Evo X will not be making it, but the other three are still in, so I thought I'd take some time to post the update and shed more light on the cars. I wanted to have a 100% stock car comparison. I really did. Unfortunately, that isn't going to happen. Well, for most of the cars anyway. The Golf R and the STI are modified, whereas the RS is stock. If you're curious, the Evo X was also modified. All have very few modifications. The Golf R went the way that seems to be very popular - tune and exhaust. It also has an intake. I asked the owner to return the tune to stock, which he agreed to do, and said he might take the intake out too. Exhaust, though, is a lot tougher to get out. He has a full turbo back exhaust so he didn't want to take it out. I can't blame him. As a result, the car wi

2016 Porsche Cayman GT4 - Faultless?

Sitting in the Paddock lookin’ pretty. Picture by Graham MacNeil (Instagram @ns_streetscene)  Driving cars fast is similar to playing and composing music. You can’t produce good music in all genres in the same way. You have to pay attention to scales, beats, appropriate tempo, chords, etc. In much the same way, different types of cars like to be driven differently to reward you. Depending on the handling balance of the car (understeer, neutral, or oversteer), weight distribution, polar moment, yaw axis location, driven wheels, etc. Luckily, I had a chance to find what the Cayman GT4 is like. I was asked to come for ride on track on a lapping day I went to ( lapping day post here ) to ride in a Porsche Cayman GT4. Needless to say, I took it. Although there is a lot you can’t tell about a car from the passenger seat, you can still judge quite a few things. Plus, I have been a passenger in a lot of cars on the track, stock, modified, and built, ranging from humble SRT4's and

Porsche Cayman V8

Well, it looks like someone figured out how to improve a Porsche Cayman.. This could inflict some (very) serious damage. A buddy of mine said Porsche purists will begin to die (as a result). That's probably true, and for that, I do apologize. However, look at this way. Porsche took away the flat six out of the Cayman and stuffed a turbo 4 in its place in the new Caymans.. At least this is naturally aspirated and (I can say from experience) is beautifully linear, and of course powerful. What better way to stick it to Porsche than effectively removing the turbo and doubling the cylinder count?

Natal Day 2016 AFRA Lapping Day

I went back to the track earlier this week for a lapping day organized by the Atlantic Formula Racing Association ( AFRA ). Turnout was great and weather was nice. There were quite a few Mustangs, actually, something I haven't seen since the S197 Boss 302's were released. This Natal Day, there was a '13 or '14 Mustang V6, first time I had seen a V6 Mustang on the track. The V6 Mustang didn't sound bad at all and had quite a few modifications. Its pace was better than I had expected too. There were also two 2015 Mustang GT's, 3 Boss 302's (two 2012's and one 2013 - all white! The fastest colour, of course.), and there was one Shelby.. a GT350R. Beautiful car and it sounded awesome.  I (very unfortunately) did not get a chance to take a video to capture the noise since we typically were on the track at the same time (but different sections). I'll try to make sure to capture it next time. For now, here are a couple of pictures.

Falken Azenis RT615k+ Street and Track Review

Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax  set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f

2014 BMW 335i xDrive M Sport Review

Post-refresh 2015 F30 3-series pictured.  Which is better, an F30 3-series or an E46? The F30 has certainly taken its fair share of heat. But if you thought I was going to say the E46, you'd be dead wrong. The F30 3-series is better. Far better. It is quicker, faster, safer, more practical, more efficient, more refined, quieter.. the list goes on. A lot of reviews and people I talk to consider the F30 to be an abomination. Frankly, I don't see it. You'd have to be mad to think the E46 is better. Completely out to lunch. I don't know who in their right mind would prefer the E46..  Trouble is, since when were people buying sports cars in their right minds? Here, lies the real problem.

2007 Saleen Mustang S281 SC Super Shaker Track Review

"Who's your green student today?" asked a friend and instructor at the BMW Club Atlantic Advanced Driver Training (HPDE) weekend in June this year. I said: "The Saleen." The response was: "Oh, boy." Mustangs, generally, have a reputation for being more power than chassis. Mustang drivers have quite the reputation for.. how to put this nicely? Taking advantage of said power/chassis imbalance. To make matters worse, this particular Mustang was a supercharged Saleen, with a honkin' Shaker scoop sticking out of its hood. Did I mention it was also a convertible? And the owner was someone who's never been on track before but clearly has the speed bug. Having had a Mustang for years and driven a few on track, they don't scare me - generally speaking - but the combination of being convertible and supercharged with a new and excited owner worried me a little. Nevertheless, I shrugged it off and got excited about chatting with the owner to find

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
