I guess this means you must be a GM engineer and a psychic.

Tell me Ms. Cleo with a PHD in engineering , why is the LT4 engine offset so far to the passenger side of the engine bay?

NVH of the motor is mostly absorb by the motor mounts; however, engine positioning is very important for weight distribution and driving dynamics....ask AUDI

Stiffer motor mounts will increase engine NVH from cold starts, spirited driving and put more flex on the mounting points and forward frame of the vehicle.

YOUR opinion is like public school on Sunday...no class...

A. You've never seen Billy Madison OMG!
B. No just a Bachelors degree
C. The engine is not offset
D. If you think you want your engine flying around the engine bay, why don't you just fully disconnect your motor mounts? Disconnect your sway bars while you are at it too. That will make your car ride smoother and move more weight the opposite direction just like YOU want.
E. Just stop

I installed my mock up engine with the mounts and it seems to be in the same exact location. I even emailed them to make sure before purchasing.

Just got the BMR mounts let see if I can install them this week.

I've had poly mounts on a 4th gen and C6Z. Didn't notice any added NVH. Wish I knew about these before I did heads/cam since they save a good chunk of weight.

NICE !! Remember to weigh them and compare to the stock ones.

And of course this too...

So the best deal anywhere is directly from RDP and there a a promo code BMR12D. Tbey have them in stock and ready to ship.

So I started installing the passenger side first because that is the side I had with no header installed.

Let me start by saying don't attempt to do the BMR mounts without removing the headers. It will almost be impossible even though BMR instructions do not mention to remove them.

BMR instructions are pretty good tbey are just missing a couple of details that they do not mention or show on the pictures.

You need to have a jack with a peice of wood so you can jack up the motor to relief pressure. I use a 2x6 of wood and a 2 ton jack worked perfectly. Also just to mention everything is done with car on a Quick Jack.

1. Removal of headers stock or aftermarket.
2. Removal of starter ( Don't need to but gives you alot more space to remove old mount)
3. Jack motor up a little
4. Remove a 10mm bolt that is holding coolant line, 3 - 15mm bolts from the mount to the motor ( don't reuse them)
5. Remove 2 - 15mm bolts to the subframe (SAVE BOLTS)
6. Jack motor up until you see mount loosen up.
7. There are a couple of clips that the BMR instructions don't tell you to remove that are clipped to the mount.
8. Remove the OEM motor mount
9. BMR instructions image 22 and 23 are tricky because they don't tell you to remove a 13mm bolt to a bracket holding wire harness. SO REMOVE 13MM BOLT AND ALSO THE 15MM BOLT FOR THE GROUND. DONT REUSE BOLTS.
10. Install BMR mount with loose aluminum spacer. Spacer goes ontop of the wire harness bracket not the ground bolt.
11. BMR instructions show wiring harness over mount I decided to leave it under so it can be further away from the headers.
12. Tighten the 4 long bolts provided by BMR. They are supposed to be torqued to 43ftlb but it's almost impossible to get a torque wrench in there. I tighten 3 out of the 4 with the torque wrench. Also I decided to put a tiny bit of lock tight just incase.
13. Install bracket to subframe with factory bolts and tighten. Don't tighten the BMR 24mm bolt yet incase you need to jack up to do driverside.
14. Lower jack all done now do drivers side.


Weight

BMR 5.5 LB
OEM 7.3

Both bmr mount 9.8

Soooo much more room with both the MM010 style and the headers removed

[Choda]

Looks like both top bolts on the passenger side has ground straps, is that correct? I dont remember seeing that when I pulled my motor.

Strong work, thank you!! Looks great too! ...Just to be clear on the weight, the OEM was the mount and the bracket?? I was under the impression there was more weight savings. Oh well.

Left bolt is just a bracket for wiring harness, right bolt is the ground.

Weight is mount bracket and bolts.
