Replacing my worn out engine mounts, need purchasing advice

The rubber has worn out on the engine mounts of my stick shift '07, so I'm going to replace them. I've been looking on the interwebs for a good deal on parts, but I have some reservations on non-OEM parts and used parts. I of course want to save money, but I don't want to buy garbage. Can anyone tell me if any of the following are reliable parts?

MotorKing

Also MotorKing, apparently

Used Mazda

Also, is this a fair deal for OEM Mazda mounts?

left mount - $177.48

right mount - $166.48

Can across these, as I'm looking to replace my mounts as well.

Motor Mounts by RX-8 Performance | RX8Performance.com
http://www.rx8performance.com/produc...m-motor-mounts - Light-weight option +$15

Might be a good option if you want a better than OEM but also save money (>$50 replace just mount's bushing in the future)....
IMO the BHR mounts are probably worth the investment tho

I have these: http://raceroots.com/index.php/products/mazda/rx8/transmission-and-accessories/engine-motor-mounts.html

They are decent for the money but I have two gripes. One, the bolt goes through but the head on the bottom is able to spin, so you have to tighten them with the engine raised, then hope you got the angle right when you drop it back down. I got around this by putting them on hand tight, dropping the motor and sticking a piece of steel flat bar in the opening to hold the bolt head still.

Second gripe is you have to tighten them more than what's in the manual. If you don't, the bolt head can move up and down enough that it'll tap the subframe when you hit a bump or transfer enough weight in a sharp turn. This causes you to spend hours pulling your hair out checking suspension and steering components.

What is the torque spec from the manual?

Actually they are not exactly the same Charles. Brice at Rice Roots knocked off my design and he didn't get it right. I have been offering these since 2010 and with over 1500 sets (3000 mounts) in the field as of 1/31/16 when I finally saw the first failure I called the customer to find out how it happened and offered to make it right.

Yeah I won't comment on any other similar designs because I don't have first hand experience with them.

The torque spec is "tighten the but nut until there's [I think] 1/8" of thread showing". I've probably got 3/8 or more and it still taps a bit.

I have a poly-filled used set from my low mile car (26k miles iirc).

Nothing wrong with them, quite nice actually, I just wanted a bit stiffer mount.

Atkins has the right at 161 and left for 156. But when i bought mine from the dealer, i got the right for 108 and left for 106! Hope that helps! Its worth getting to know your local dealer if you have one!

I've got a fair cross section of the BHR parts and I'm happy with my BHR mounts.
