Excelerate Performance : Motor Mounts V2



Hey Acurazine

As some of you may have heard, we've run out of our XLR8 motor mounts! The last set left the shop early last week, and it was bitter sweet.

The question now is to make, or not to make; so we're curious who out there is interested.

Pricing? We're not quite sure yet. We hope to keep them around the $300 figure they were at before, but, a new design may bring new pricing.

If there's enough interest, maybe we'll work out some details for a group buy. What's everyone think?

My motor mounts are starting to show their age and I intend on replacing them sometime in the next six months.

However, I'm looking for something more along the lines of the OEM firmness. Maybe a bit more, but (from what I've heard) even the 62a mounts are much firmer than stock and aren't overly enjoyable for daily driving purposes.

All I want is something that doesn't fail as quickly as OEM, at a reasonable price ($300 was just fine). Maybe a wee bit stiffer.

Sounds good to me, thanks for the input! Perhaps we'll have something for you when the time comes to replace your current ones!

Would like a more durable option for when my OEM ones go out again...seem to last 2-3 years or so.

~1 month '04 6MT owner here and I'll likely be replacing my mounts within a year, but I haven't even checked them yet. First owner put a casual 67k on the car, so I'm thinking they're okay, but maybe not. As for the feel I'd be looking for- probably something near stock but a little firmer/more robust. Comfort was one of my primary reasons for getting the car, but I'm also a canyon carver, so there's that. Willing to spend <$300.

Also, it should be interesting to note that @sockr1 in another thread mentioned something about using all mounts from the set minus the rear mount which had a tendency to create more vibrations than the other mounts. I think he ran 3/4 from a set (not sure which atm), and a stock rear mount. Just thought I'd throw the info out there. Hope it helps.

I would be interested in the design aspect.
the factory mounts are the worst designed mounts ever for a tourqey v6

I agree with tacobell. I am running XLR8 62 (front and side only) and kept the rear OEM. Once I replace my axles, I will see if the vibration settles down more, but before my axles went to hell, vibration was noticeable.

Something in between OEM and 62 but with durability and minimal vibration would be perfect for the daily driver.

aftermarket mounts are almost a necessity on the 3G so i hope more are made available

but to keep costs down (to both customer and supplier), xlr8 should offer just a front and side set. there are way too many vibrations introduced when adding an aftermarket rear mount. with the AC on, i was embarrassed to have anyone in the car (that was with 62a also). i've now been running 75a front and side mounts for about 1.5 years now and the rear on oem. this would help costs all around.

my other suggestion is to make the inserts fill the entire inside of the xlr8 mount. right now there's surface area not being used and it could be better at distributing the load.
another suggestion is to put some kind of vibration damper (such as a rubber bottom layer on the underside where the mount sits) on the bottom of the mount to dampen the vibrations between the mount and the frame it bolts into

Side mounts sold with an OEM rear is an interesting thought..

I'm also interested in something that is as similar to OEM as possible but also being durable (if this can be achieved). I've now owned two 3G's and its become annoying for both me and my wallet having to replace the damn things. I'm not an engineer or anything, but my guess is that the stock passenger side motor mount design is poor and doesn't control the torque of the motor that well, causing all the other ones to bust. The high under the hood temps too accelerate the wear. Hell, my sister's slow and weak Nissan Versa had a better looking/designed side motor mount - it was an arm that ran parallel to the length of the car and was attached to the firewall rather than something that looks like the nub of an amputee.

Would it be possible to then offer, say, the side and front mounts as they are (either 62a/65a and 75a), but then make the rear one out of a much softer material? I suppose OEM is an option for the rear mount, but we all know it'll fail all too soon again.

I'm wondering what kind of engineering (or even pin pointing why the rear mount creates so much more NVH) would be required to get the rear mount up to a happy medium for daily drivers. It sounds like you could even reuse your design for the front and side mounts and really focus your attention on the rear.

I do like the look of the aftermarket mounts for the TL. They seem to clean up the bay nicely.

Sucks, I was planing to upgrade my motor mounts real soon looks like ill have to wait. Im new to the 3G TL scene and I am sure interested in a set of aftermarket mounts. Count me in. What do you think the turn around time frame is when new mounts can possibly be available?

So lemme get this straight. You're suggesting a price increase, to cover the additional cost of fixing the issues with your 'design' ?

​​​​​​Sleeved polyurethane bushings MIG welded to some 1/8" steel plate. Materials cost can't be more than $50.

The $250 price that some of you paid from out Honda/Acura storefront is a discounted price (the MRSP was $300) since we're thankful for all of our continued support on the forums, and would like to say thanks by passing along some discounts!

We're still not sure what we're going to do, so the $300 was just a rough idea; nothing is certain yet!

I'm looking forward to seeing the mounts you create yourself, for $50.

How do we check if they're bad, in other words, what are the symptoms? my 08 TL is making clicking sound sometimes, I don't think it's from the axle.

I too had to remove the rear mount and keep it OEM for a less vibration. Front and Side mounts at 62A have little to no vibration. Was thinking of upgrading to either 65A/75A later down the road as I'm either use to the vibration or don't have any.

Rookie question. What are the noticeable driving symptoms of the OEM mounts going out? I'm at 138k, 2nd owner, bought the car at 96k & the previous owner was very easy on it. Lately I've been noticing cabin vibration upon throttle application in the upper gears and starting at about 45 mph. My first thought was wheels. Trouble shot that out. Second thought was tires. New tires have not solved the problem. (needed new ones anyway) Was now moving onto axles.

I am wondering why people would want a soft rear mount and harder side mounts. In my integra when I used to race the rear mount is the one I always broke. I upgraded to a solid rear mount but the two front mounts were soft and never had an issue again. I am actually looking to get the hardest rear mount currently for my TL.

A visual inspection is the best way to go about it, if the bushings are torn or have excessive rotting then you have your answer! If you can get an extra set of eyes to watch the engine while it's under load (and there's quite a bit of movement) then that is usually a pretty good indicator as well!

Also, if you have a manual then get on the throttle a little bit and let off. Sometimes if they're bad enough you can see extra movement in the shifter.

Good luck!

that sounds exactly like axles

so far it's working for me! i've ran this setup for over 16 months now and no issues (front, side stiffer and rear oem) and i have about 290-300 hp to the wheels (not normal stock power). the vibration from the hard rear mount was too embarrassing for me to drive people and turn the ac on at the same time...

It was not bad, it didn't vibrate the car nor the dash board. The engine did feel more solid when shifting between gears, it used to buck before. When I went to all solid motor mounts that's when everything vibrated. Even loose change in my cup holder area, which was pretty annoying.

Do you have the mounts anymore? My front one tore up pretty good, only thing I could find on the site were the 6th gen mounts. Someone came online to assist me, said she'd get a sales rep to help, no one joined the chat after about 10 minutes. Asked if they could contact me by email, said they would but never heard anything back. Ended up ordering the Innovative mounts.
