Hi all,
I'm looking at getting the Hinson Motor/trans mount set. I am debating between the oe height and the shortened version.

Is there any drawback to going with the shortened version over the oe height?
Is there any benefit aside from the engine bay clearance?

with the shorter mounts, the spring will rest against the oil pan when unloaded. nothing has happened, and nor i do not think it will. it is really the only thing to talk about in regards to these motor mounts.

amt did not have their mounts out when i bought the hinsons, for i would have certainly purchased those instead.

Hey, thanks for your input. I would like to clarify so I understand.
The spring you refer to is the leaf spring?
If so, have you confirmed that when the car is on the ground, the spring does not contact the pan?

Also, have you heard of any issues with failure of the shorter mounts compared to the OE height?
Did you notice any change in vehicle balance with the lowered center of gravity?
What were your overall impressions from this modification? Any regrets?

The spring you refer to is the leaf spring? Yes
If so, have you confirmed that when the car is on the ground, the spring does not contact the pan? No contact when on ground - that would not be a viable part. Contact is only when unloaded (on a lift, wheels hanging)

Also, have you heard of any issues with failure of the shorter mounts compared to the OE height? Never heard of a failure difference between the two.
Did you notice any change in vehicle balance with the lowered center of gravity? You won't notice this, the difference is too minimal
What were your overall impressions from this modification? Any regrets? It's the go-to mount. It is more rigid than stock, so you will notice more vibration transfer through to the chassis, but the consensus feedback is that it's only felt when idling at a stop.

I'll be getting a set myself soon too. You'd only want the shorter mounts if you're planning to add an intake that could use a bit more clearance, otherwise use the standard ones.

I'll let other chime in on short vs. OEM as I only have the OEM height, but I will tell you to wrap you mounts with a decent quality hi-temp tape or shielding. If you have headers these have been known to start to melt without some shielding of sorts.

word. same to everything above.

although i was in a hurry and did not wrap mine. i suppose i will have to check and see what they look like after three years...

Check out AMT Motorsports. Their equipment does not have heat related issues.
@Mark@AMT Motorsport will be able to help you out.

While we are on the topic I’m going solid aluminum so I don’t have to worry about heat. Anything else I should know before doing this job?

Apocolipse

Rumor has it knock sensors may be unhappy

I can tell you one thing that's for sure. I have the AMT mounts, and there is nowhere NEAR the amount of up and down play (engine/torque tube) when mating the trans/diff back up with the TT. It made it a litter harder, but ultimately we got her in.

I am very excited for this season with my AMT!

You may have trouble with the KSes and, unless you are building a track-only car, you will not like the noise and vibration when you're driving on the street.

10 4, understood.

should I do the trans while doing the engine mounts?

Apocolipse

You can only have 1 end with solid. Engine or trans. Not both.

spoon man

couldn’t you do the semi hard ones like Hinson and trans solid?

@Apocolipse i haven’t bought the mounts yet. I’m in the part buying phase and lining up the next two rounds of mods. One is a Dyno visit

Apocolipse

Awwwyeaaaaa best session for sure.

You can mix and match - the reason is you need driveline flex for thermal expansion. When the tube heats up it gets longer.

spoon man

Got it. Thanks man!

Just throw the oem metal shield on the top and they will be good to go.
