2012 Mustang Boss 302 - Stock vs Heartthrob Flowpack Axle-Back Video

Image
By




As promised, here's a video comparing the stock axle backs to the Heartthrob Flowpack units I installed a few weeks ago. The video shows start ups, both cold, and a few revs after the car had warmed up. The video doesn't do the difference in volume justice but you can tell the difference in tone with a good set of headphones or speakers. For a full review, go the original post: 2012 Mustang Boss 302 - Heartthrob Flowpack Axle Back Exhaust.

2004 Audi TT 3.2 Quattro DSG Track Review

By
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...

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

By
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 load...

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...

Michelin PSS vs Firestone Indy 500 - Track Review

By
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 l...
