2017 Camaro ZL1 Beats Previous Generation’s Nürburgring Lap Time

The new 2017 +Chevrolet Camaro ZL1, expected in showrooms by the end of this year, just beat the benchmark set by the last generation ZL1. With a lap time of 7:29.60, it is 11.67 faster faster than the last generation and even beat the last generation Z/28's time of 7:37.9 - which was done on Pirelli P Zero Trofeo R tires, far grippier than the Eagle F1 Supercar used on the ZL1. The car used is unchanged from the one you'll be able to buy, aside from the installation of data acquisition equipment, a roll hoop, and Sparco racing seats with six-point harnesses. Otherwise, the car was production stock and included the following:

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 handlin…

Chevrolet 1LE & Grand Sport - How do they do it? Part 1

Recently, Chevrolets seem to have been punching far above their weights and a lot of people (myself included) are impressed. Sure, Corvettes have always been formidable track cars, but they're low, light, purpose-built, and didn't blow expectations - just provided excellent value. Now, all +Chevrolet  track cars, especially Camaros, seem to be overreaching and, combined with excellent chassis tuning, have been doing wonders for GM's chassis engineers' image. I decided to take the time and do some research to try and figure out what GM is doing that others aren't (or can't). Before I start, I'd like to point out that this is based only on my own understanding and research, not an interview or publication by GM, so take that for what it's worth.

Since I haven't posted about the latest of Chevy's track-focused models/trim packages, I thought I'd first take this opportunity and talk about what you get. Whether you're looking at a Camaro V6…

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 2016. 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 clutch auto, and car…

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 SS2016 Mustang GT0-30 mph1.6 s1.7 s0-60 mph3.9 s4.4 s0-100 mph8.9 s10.5 s1/4 mile12.3 s @ 116 mph13.0 s @ 112 mphbraking 70-0 mph147 ft157 ft300-ft dia.skidpad0.98 g0.94 g610-ft slalom43.9 mph43.3 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've already read plenty of other reviews so I will try to give a different perspective. The perspective of a guy who owns this type of car, enjoys it the way it was intended to be enjoyed…

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 will be…

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 Evos to Co…

How would a Mustang 3.5L EcoBoost compare to the 5.0L V8?

Ever wonder how a 3.5 litre EcoBoost might fair against the 5.0 litre V8 in the Mustang? Of course you have. Ever since Ford dropped it in the F150 (and perhaps well before), everyone has been wondering how it would perform. There are basically two camps; those who think it would be awesome because of tuneability and power potential and those who think it means the death of the V8 in the Mustang. If you are in the latter group, we seem to be good so far with continuous upgrades to the 5.0 litre Coyote and the brand new Shelby GT500 which still uses a supercharged V8 as it has been for over a decade and multiple iterations. But what if...

Well, it seems we are closer than ever to finding out the answer to that question. American Trucks recently got together two crew cab, short box, 4x4 F150's but one has the 5.0 litre V8 and the other has the 3.5 litre EcoBoost V6. There has been a few comparisons between 5.0 litre and 3.5 litre EB F150's, but this seems to be the most direct …

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.…

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…
