This 4140 Billet Steel flywheel is built to be lightweight while strong enough to handle power and abuse for many years of operation. A lightweight flywheel gives the car the ability to rev up and down faster, your car will be able to accelerate faster in lower gears and thus be able to accelerate faster due to the freed up weight. They also will allow less strain on the crank and transmission due to their lighter weight and less parasitic drag. On turbo applications you can also reduce boost lag. The steel model is SFI certified and can be resurfaced, the aluminum version has a replaceable face but are more used towards race vehicles who need every last ounce of power. The Steel flywheels end up being more durable due to the strength of the steel vs aluminum.

Comfort and Great for Standing
Definitely the best shoe for standing on ur feet all day. I stand for about 7.5 hrs a day and this has changed things for me drastically. The foam makes a difference and the shoe is stylish as well.

Sturdy and slim yet spacious and comfortable
Color: Derrick Brown, Size: One Size
Very nice! Fit about 10 cards total as well as about 10 bills. Would like to see how it holds up as I just got it today but I like it enough to write a review! I really like this wallet. I’m a bit of a stickler when it comes to having things near my butt area, but this fits great in my back pocket. I know it’s a front pocket billfold, but hey, I live on the wild side. I can wait until corona passes and I can walk up to the bar and whip this bad boy out to start a tab. It smells like a cowboy but presents like a stock broker. If you didn’t know me, and I pulled out this wallet, you would be very mystified. “Is this man classy? I think he might be! Look at fossil Derrick Front pocket Billfold” “wait, is that Derrick himself?” I’m not Derrick, but thinking about switching my name to Derrick because of how good this wallet is. The leather looks like it was cut from a Waygu bull with horns too big for a Cadillac. I’ll tell you what, this SOB is purtttttty. Would recommend to friends, family, and acquaintances. I would never pull this out in front of my enemy, in fear he might get the same wallet as me. The fossil message said this wallet is one of a kind, so the odds of someone else getting the same one is impossible. So, if I am the only one who has this wallet, how will anyone in the world find this review helpful? I guess you’ll just have to take a chance at getting a similar wallet to mine.

Nice simple wallet
Color: Derrick Brown, Size: One Size
I purchased this for my husband. It’s one inch shorter than his previous wallet, which had us worried at first. However, it fits all his cards. It has a nice look to it and time of good quality. My husband says he’s happy with it and really likes it.

Expensive, but a well-made slim front pocket wallet
Color: Steven Medium Brown, Size: One Size, Color: Steven Medium Brown, Size: One Size
This is a review for the Fossil “Steven” Front Pocket Bifold Wallet. This wallet measures 4.5 inches x 3.0 inches. It is made with soft-touch leather all around (which feels fantastic), and the build quality is top-notch. It is definitely smaller than a typical wallet, but is still able to hold a good number of cards. I could easily fit about 12 cards into this wallet while still being relatively slim and compact. The wallet is discreet with only a “Fossil” logo that is embossed on the inside. The fabric lining of the cash compartment is treated with an anti-microbial coating. There’s more information about this coating on the manufacturer’s website, but it seems this is to protect against viruses and germs that maybe on cash notes. And while other wallets feature RFID Blocking, this wallet does not claim to do so. This wallet is definitely pricey. And you can easily find other slim wallets for much less. But, I suppose I’m paying for the brand name - and I do like Fossil products. So if you want a brand name wallet that is well-made and slim - this is a good option to consider.
