Interview: eSports Commentator and GT3 Racer Matt 'Sadokist' Trivett

If you aren't at all into gaming and online championships - eSports - you may not know who Sadokist is. In fact, I had no idea who he was when I met him either.  I just saw a "new" E46 M3 GT3 race car at the track that I had never seen before. I'm not exactly a "veteran" of our track - I had only been frequenting the track for about 5 years at the time - but it had been long enough that I recognized most of the regulars and the race cars. It looked like a proper build and the trailer was parked next to the other two local M3 race cars running whose owners I knew very well, so I went to chat and ask about the car.


I learned later that Matt is a bit of an eSports celebrity. You can't argue with Twitter. But you wouldn't know this just talking to him. He's very down to earth, so much so that he simply thanked me when I "welcomed" him to the track... even though he went to his race school as a wee lad 4 years before I even first stepped f…

How Limited Slip Diffs Make You Faster on Track

Over the years, I've found that limited slip diffs (LSD's) are some of the least appreciated performance parts you could get (or upgrade) for a car. LSD's make a big difference, though, because they can vastly improve how early you can get back on the power and, therefore, how good your corner exit is.

That last bit is very important if you're driving on track and want to get a good lap. You don't have to just take my word for it, though. F1 royalty Sir Jackie Stewart puts an emphasis on the importance of corner exit. When Captain Slow was sent to him to cut 20 seconds off his lap time (Top Gear Season 8 - Episode 5), Sir Jackie told him: "the exit of the corner is FAR more important than the entry of the corner, with regards to smoothness."


You really need to nail the exit. And to get a better appreciation for and understanding of LSD's, you first need to know how open diffs work and where they fall short. If you're not sure, brush up on Differe…

Why an Open Differential Doesn't Work on Track

I wrote a tech post comparing various open and limited slip diffs for a comparison and I found that a lot of people were asking questions. To simplify and make it easier to read, I decide to break them up for a future tech article about handling. Make sure to stay tuned for two posts on limited slip diffs this week!.

WHY DO YOU EVEN NEED A DIFFERENTIAL?

A differential's job is to allow two wheels on the same axle (or two axles in a 4WD drivetrain) to spin at different speeds so a car could smoothly go around a corner. Why do the wheels need to spin at different speeds? Each wheel on a car has to travel a different path to reach the end of the turn. You can see that for yourself every time you drive on snow covered roads or muddy trails.


If you take a turn, you'll see that each wheel/tire leaves a separate track (arc) on the road, which means they all have to travel different distances. And since they also have to travel different distances in the same period of time - the time…

Ford Finally Announces HP figure for 2020 GT500

Ford has been teasing the new GT500 for months now and many details are already known about it like specs and even top speed and downforce figures. But the one thing that remained a mystery is the exact horsepower figure. We knew it was going to be over 700 hp, but exactly how much wasn't known. But we FINALLY have an answer now in the form of a video. And what more appropriate way to announce a mad 700+ horsepower figure than a burnout video?


This figure puts it WELL above its primary rivals, namely the Challenger Hellcat with 707 hp and the Camaro ZL1 with 650 hp, but it is still shy of the new Hellcat Redeye with 797 hp, but it should be much lighter, to the tune of 200-300 lb. And while the Challenger Hellcat is a massively capable grand tourer for its size and weight, the GT500 should be in a different league on track, especially with the Track Pack.

Getting that much horsepower makes it the most powerful production Ford ever and the most power and torque dense V8 in the wor…

2020 G80 BMW M3 to bring more than 500 hp and AWD

The current (and outgoing) BMW M3 upset quite a few purists when it switched to turbocharging to boost power from a long line of naturally aspirated engines. It looks like the upcoming G80 M3 based on the new G20 3-series is looking to buck the tradition again by being the first ever M3 to offer AWD/4WD. That's right, it looks like the next M3 will send power to all four wheels according to a report by Auto Express.

Of course, it won't be the first ever M-car to offer AWD. That honour goes to the current M5 which was the first M sedan/saloon car, so perhaps that should have been a sign of things to come. It makes a lot of sense, given the competition. Fast Audi have been AWD for several generations and recently, AMG announced that the future of AMG is four-wheel drive.


Tough Competition

Audi is nearly synonymous with AWD and with AMG now switching to AWD, a RWD M3 would (unfortunately) be quite handicapped in terms of traction and objective performance. Competition isn't o…

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.…

Michelin PSS vs Firestone Indy 500 - Track Review

A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity.

Grip is noticeably lowe…

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…

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.
