Before we get to the meat and potatoes here (there's not much to this section) if you have heard that your BK is "missing" a differential mount or that adding a second one somehow upgrades your car's performance, it doesn't. The car was designed that way. Adding a secondary mount will only result in additional ride vibration being transmitted through the body. Upgrading the differential mounts on this car offers next to no improvement (arguably), and that is why they are not covered here; so, moving on...
I will typically link to the mfr's website for these parts; order from the reseller of your choice for best pricing.
Engine Mounts
With two options, one cheap and one a bit expensive - you may be asking yourself - does one do a better job than the other? Answer: not really. OEM motor mounts, while not terribly stiff, are quite fine, and show no sign of failure or debilitating weakness up to 400whp. Stiffer motor mounts means less play in the motor as it torques, and less energy lost in transmitting power down the driveline. Therefore if you are adding power to your car it would make sense to solidify the motor's place in your engine bay. The harder the motor mount, the more vibration is transmitted to your cockpit, things that never vibrated before will jump around now. Bear this in mind; you may think it's cool at first, but alot of people eventually tire of their interior rattling and buzzing.
- CP-E Mounts (50 or 60 duro) - Offered in two flavors - hardass, and shake your fillings out hard. Quality products for sure, though a bit on the pricey side.
- Megan Racing Mounts (70 duro) - Good quality, no-frills design, very affordable. Megan is known and bears no introduction; this is not a cheap chintzy part that's going to fail, but it was not engineered to be any fancier than had to be. This means you save bucks; this is also a holy shit hard motor mount, which means if you are going for drift application, this is your mount.
Transmission Mount
Notice the singular case of the title. This component is arguably the largest soft spot in the driveline of the car in terms of mounts. The transmission experiences quite a bit of play due to the soft OEM rubber mount. There is one product available -
- Megan Racing Mount (70 duro) - See above; basic no-bullshit part. Also not built for comfort in any sense of the word.
You have one other option - that is to take your OEM mount, and fill it's voids with 3M Window Sealant Urethane. This is a common DIY from the old days when most cars did not have polyurethane bushings/mounts available, so folks pretty much made their own. If you do this method you can pretty much consider your mount now a ~60duro strength mount, and call it a day; personally I'd go with the actual built & sold product myself just for piece of mind that I got something that was at least sort of engineered, vs. a shadetree solution. |
