Over the last few years, the increase in popularity of Powerflex's engine mount inserts has made them aware of the lack of performance engine mounts suitable for both street and track use.
Listening to market feedback from BMW owners initially, the focus was to supply a replacement for the oil-filled, often soft and torn mount that wouldn't ruin the street driving experience by compromising NVH transmission, but would improve and increase engine control. Not an easy task, but a challenge they were happy to accept!
After many months of development, they are pleased to be releasing PFF5-4650, their 'tuneable' Engine Mount.
This mount is designed to fit 4, 6 and 8 cylinder 3-series BMW. Fitment includes E36, E46 and E9X M3 only. It will fit diesel models, however there will be a noticeable increase in vibration at lower rpm levels.
The black anodized body of the billet-aluminium CNC machined mount houses 2 polyurethane bushes with special fluting and shaping (Black 95A) to isolate the engine vibration from the chassis.
What Makes It 'Tuneable'?
Whether it's a daily driver, or track weapon, PFF5-4650 can be tuned to suit. It comes with 4 insert pins which can be fitted into the mount whilst on the vehicle. With the pins fitted, it fills internal voids stiffening the mount by around 25%. This makes it ideal for improving the car for the occasional track day, and when finished the pins can be removed without suffering any excessive NVH.
With the popularity of our Black Series parts with BMW owners, we are also offering the mount with Black 95A durometer bushes fitted.
With the pins included and this super-hard configuration, the increased load for the same given movement is a whopping 675% at 4mm over the standard M3 mount. As you would expect there will be a significant increase in NVH, making it suited to the hardcore enthusiast only.

Finally found the perfect backpack!
Color: Apricot, Size: 17.3 Inch
I’ve been searching for a backpack that could fit my 16-inch laptop and my other uni stuff since i commute, without looking huge on me, I’m a small girl, so most big backpacks just look bulky and awkward. I wanted something slim and sleek, not one of those backpacks that stick out and have that “belly” shape.
After a lot of searching, I finally found this one, and I absolutely love it! The material feels really high quality, and the design is just perfect. I got the 17-inch size, and it fits my 16-inch laptop comfortably.
There are so many pockets for organization, plus a separate padded compartment just for the laptop, which I really appreciate. It also has a handle that easily slides over my suitcase handle, which is so convenient for traveling (I travel a lot, so this feature was a must).
It’s comfortable to wear, the straps are adjustable, there are bottle holders on both sides, and overall it just looks clean and stylish. i got the beige color one. which i love.
I’m really happy with this purchase it has everything I was looking for. I’ll attach a short video showing all the pockets and features because it honestly deserves it!

Perfect and not bulky
Color: Apricot, Size: 17.3 Inch
Love this slim backpack, plenty of room for my laptop and so much more. Lots of zipper and mesh pockets. I like the separate compartments for the laptop. It’s well designed and very functional. I wanted something that was not bulky and this fit the bill, it’s really great. The material is nice and easy to keep clean. Seems well made, I’ll update down the road if that changes. I recommend this backpack.

Perfect work travel bag!
Color: Black, Size: 14 Inch
Perfect work bag! I was looking for something for a petite frame. Can fit a lot in it, worth the money, love all of the pockets. Can carry two ways - either with handles or wear on back like a backpack

Perfect backpack to use as a purse
Color: Champagne Brown, Size: 14 Inch, Color: Champagne Brown, Size: 14 Inch
I LOVE THIS BACKPACK! It's perfect as an EDC backpack used in lieu as a purse. It's small enough to use daily and to keep basic necessities in. It has a main compartment, a basic compartment for a laptop or iPad, and a small front pocket. There is a small area that closes with a snap where the handle comes out of that can be used for storage as well. I like to keep my sunglasses or vape in it. I like to wear a backpack when shopping, it makes it easier to have my hands and arms free and I also don't have to worry about my purse in a cart and someone dipping into it when I'm not looking. While I like to wear a backpack, I don't need an ACTUAL backpack used to carry large objects and this fits the bill. I'm able to fit my wallet, phone, 10" iPad, journal, tech kit, small makeup bag, keys, glasses, gum, coin purse, misc. pouch in it and it still has room at the top. The quality is excellent, as all Golf Bags are. The color is a beautiful neutral medium taupe (I got the light brown/cappuccino? color) but I would love this bag in black, blue, and beige! The blue color is such a pretty blue!
