E46 Dinan S1 BMW M3 - Track Driven

A few years ago, I was still a student and I had a class called Internal Combustion Engines. It was easily one of my favourite classes, as you can image. Studying engines, calculating hp, torque, efficiency, and exhaust flow for grades? Sign me up! It wasn't just the content, though, as magnificent as it was. The class itself was taught by the coolest prof there is. You may think you've had a cool prof, teacher, coach, or instructor, but I've got the standard by which all educators must be measured.

For one, he or she has to teach something that is cool.. does it get cooler than Internal Combustion Engines? (No, in case you're wondering). This one is also a true gear head, so much so that he sticks around after class and argues about cars, performance, lap times, and racing. And occasionally does so in the middle of class.. For one class project, I proposed comparing the engines and specifications of the C6 Corvette ZR1 and the Ferrari 599, in an attempt to "reve…

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…

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…

Koenigsegg Gamera: 4 Seats, 4WD, 3 Cylinders, and 1700 hp

Meet the Koenigsegg Gamera. This car brings so many firsts, not just to Koenigsegg, but also to the entire automotive industry. For Koenigsegg, it is the first car to have 4 seats, the first to have 3 cylinders and the first to have all wheel drive. Koenigsegg calls it the world's first mega-GT (gran touring) car, and I think they're right. For the world, it brings the first four seater, mid-engine, hyper car. Koenigsegg says it wants to bring the "exciting performance traits of a mid-engine two-seater megacar with the practicalities of a four-seater car with more luggage space" so the experience can be shared with "family and friends." Clearly, I need better friends...

With 1,700 hp on tap, you are sure to impress those lucky enough to be your family and friends if you own one of those. Of course, a three cylinder engine with 1,700 hp is likely to have all the driveability and flexibility of a farm tractor so Koenigsegg doesn't rely on it for all the …
