BMR Chevy SS and Pontiac G8 Motor Mount Kit (Polyurethane) RedEngine movement (deflection) is wasted horsepower, and that power is yours! BMR's suspension wants you to take it back with its polyurethane motor mounts for 2008 2009 Pontiac G8s and 2014 2017 Chevrolet SSs. BMRs new motor mounts (MM300) are far superior to the bulky, oil filled hydraulic stock motor mounts, which are designed for comfort, not performance.

Engine movement (deflection) is wasted horsepower, and that power is yours! BMR's suspension wants you to take it back with its polyurethane motor mounts for 2008 -2009 Pontiac G8s and 2014 - 2017 Chevrolet SSs. BMRs new motor mounts (MM300) are far superior to the bulky, oil-filled hydraulic stock motor mounts, which are designed for comfort, not performance. BMR manufactures its MM300 polyurethane motor mounts in its Florida facility from MIG-welded -inch plate steel with 6061 billet aluminum machined spacers and 95-durometer polyurethane bushings. The kit is completed with Grade 10.9 hardware.BMR's suspension designed the MM300 to be the perfect (100% bolt-in) motor mount for any power level or application (street performance, drag race, and road race) where engine deflection needs to be reduced. The factory hydraulic motor mounts are designed to dampen engine vibration, giving you the smoothest and most comfortable experience possible. Unfortunately, this does little to limit engine movement. This deflection means lackluster throttle response, slower reaction times, and less accurate shifts in manual-equipped cars. BMRs MM300 polyurethane motor mounts limit engine deflection, while isolating much of the engine vibration from the vehicles occupants. This means you wont feel a big increase in NVH. The reduction in deflection leads to more power transferred to the tires, improving your driving experience on both the street and track.This Part Fits:

Made of carbide steel material and has high hardness characteristic
The shank that fits into the drill has three flattened surfaces, making them less likely to slip in the chuck. Much much easier to use than hand reamers!!!
NOT AS DESCRIBED: The title says these are both carbon steel and carbide steel, but they are not the same. carbon steel and carbide are not the same; they are fundamentally different materials with distinct properties. Carbon steel is a metal alloy of iron and carbon, known for flexibility and toughness. Carbide (often Tungsten Carbide) is a ceramic-like, extremely hard, and brittle compound used for cutting, offering much higher wear resistance and heat tolerance.
These have the look and feel of carbide, and not carbon. In my expert opinion.
Most tires are "steel belted radial" and it is hard to ream through the steel belts by hand. I have spent HOURS trying to ream through difficult tire punctures by hand! These bits make quick work of the process. If needed, the sizes can be used gradually from smallest to largest. They leave a smooth sided hole which is less prone to leakage when the tire plug is inserted.
Excellent value for the money! Highly recommended.

Makes plugging faster
It makes to process of plugging a tire a lot faster. I think you need to use a drill with these. Unless you had a hand drill with a chuck to tighten down on the bits, you probably wouldn't be able to use like a t-handle because you couldn't pull the reamer bits out. Just in case you were thinking of keeping this in a roadside emergency kit. It turns probably a 30 minute job into a 5 minute job with a drill though. I attached a picture of the hole after I was done reaming with all 3 sizes up to the largest.
