XLR8 Performance Engine Mounts - Acura TL '04-'08 ALL
Finally they have arrived.
XLR8 Performance’s Engine Mounts were engineered with longevity, performance and value in mind. Many Acura enthusiasts are having issues with broken motor mounts. These mounts are heavy duty mild steel mounts that have been coated with a satin black finish and improved polyurethane bushings that range in firmness. Controlling the durometer of the polyurethane inserts minimizes engine movement. We offer 3 different durometers of inserts, which are available at no additional cost. When ordering, specify whether you want: Street (62A), Strip (75A) or Race (85A) polyurethane inserts. The polyurethane inserts also have a lifetime warranty.
EDIT ADD BY ADMINISTRATOR RON A 18 JULY 2015: THE LIFETIME WARRANTY MENTIONED HERE HAS NOT APPLIED FOR SEVERAL YEARS. THE WARRANTY NOW IS ONE YEAR.

Can you show us a pic with the mount disassembled ?
From the assembled pic, the XLR8 mounts look similar to the Innovative Mounts. What design features do the XLR8 mounts have that will resist or prevent the donut problem ?
If a person initially purchased a set and then decided later that they wanted a different insert firmness, can a person change the insert without a press ? Will the polyurethane inserts be offered separately ?

The bushings are pressed in. If you decide you want to change the bushing you would need to use a small press or vise and press the center pin out and then use a punch to force the bushing out. Then you install the new bushings and reinstall the center pin.

Can u just explain the different stages that are available(62, 75, 85a) and what would be best for a fully bolt on TL 6spd w/o precats and s/c

Can you show us a pic with the mount completely disassembled, showing the inserts removed and showing the flat surface of the bushing ? Please This would go a long way in helping us to understand.
Will the polyurethane inserts be offered separately for those that wish to experiment with the different durometers ? Any idea on the price of individual inserts ?

Yes we can sell the inserts separately. I haven't priced it out yet b/c I've never had to sell multiple bushings to someone. Most ppl just buy what they want from the beginning and keep it in their car. However, I will get answers for you.

The 75a would be more for a aggressive driver than the 62a bc I wouldn't want the 62a to wear out on me. So it be safer to go with a 75 a?
Once again I'm a fully bolt on 6psd w/o precats and s/c.

62A is sufficient for most street setups. Those who demand more traction and less engine movement and don't mind the additional vibration should get 75A.
#19
Unfortunately I have all these parts at introductory prices so I can't go much lower. If you buy both I can give you a promo code to take $10 off the mounts.
I have also put up most of the funds to design these parts months ago so I have to recoup some of my costs soon. And if you buy both parts though you will get a reduced shipping cost.

... I've installed the Innovative Mounts numerous times and I'm well versed as to why oem mounts FAIL...
Looking at the first picture... You automatically see that the XLR8 mounts keeps the design of the oem mounts... Innovative did not and the mounts fail because of it
Josh... Looks like it's going to be a good year for the 3RD Gen Acura TL... You've come out with a load of goodies

We're also working on a clutch setup and some new brake-related items. When we have more info though we will post it up. Good things to come for 2010.

Can you explain more ?
When I look at the assembled XLR8 mount, it looks similar to the Innovative mount. So, I am really interested in what you are seeing different.
Now, I am sure that the XLR8 mount does have a different design on the inside. But just viewing it assembled in the pic.... I don't see what you see. Please help a blind man out

ok look at the pictures again... in the IM the bushing is "floating"... XLR8 the bushing is attached to the base and the bracket is "floating" (ie. as oem is)... you tell me which is better

Understanding how engine rock stresses are applied to the front an rear mount, I fail to see how these mounts won't donut out as well?
The fundamental design appears to be the same... the difference in these mounts seems to be the upper section of the front/rear mounts have the extra support "flap" that folds over the sides. They seem to be "inverted" IM design.
IM: Lower mount with side brackets, upper mount attached to cylinder
EX: Lower mount attached to cylinder, upper mount attached to side brackets.
Both mounts attach together with a single axial bolt through a poly donut.
Unless something is different on the inside of the donut, these mounts appear to be of a very similar nature, and will be subject to the same stresses that's causing the IM mounts to fail.
Seeing one disassembled will help...

I read that, but must confess I didn't understand... Pics speak volumes... and to your point above about the donut float, interesting, and likely true that it's better on the frame side (the whole unsprung weight in suspension systems), but I fail to see how that addresses the stress issue that's causing the failures in the IM mounts.
My point is innermost section of the mount, the metal sleeve inside the poly that the axial bolt slides through, is the stress concentrator and cause of failure on the IM mounts. Until we see one taken apart on that, I can't see the difference.
One way to think about fixing the IM mounts (which may be in these) is to machine a larger oval/flatttened inner steel bushing to spread the vertical forces across more poly... Just a though. Josh eluded to "flattened" above, but I'm not getting it.

You guys are brutal. When the Innovative mounts were released I didn't see this sort of scrutiny. However, in order to show how the XLR8 mounts are better for the TL we did dissect two mounts, one from Innovative and one from XLR8. Both these mounts are from a 2nd gen CL/TL - one is our prototype mount and the other is the Innovative side mount. Both mounts have 60-62A durometer bushings.
Here's a pic of both sample mounts side by side with the bushings removed:
Our collar had to be pressed out. The Innovative collar came out with some force by hand and a socket.
Pics of the bushings. Note that the XLR8 bushing is twice the width.
Even our collar is substantially larger:
Now here is why the Innovative mounts are doughing. I applied the same pressure to both bushings. The red bushing is the Innovative bushing; the black is the XLR8 bushing.
No wonder why the bushings are donuting b/c if I can compress it by hand, with my left hand which is weaker, then I'm sure a motor is doing much worse.
Also here is the pic of the inside of the XLR8 mount:
There is only a 10mm gap between the 2 bushings and that is so you have room to punch the bushing out of the mount.
Innovative makes a thinner bushing and therefore welds in circle plates on the inside of the mounts.
I sell Innovative mounts and I think for the most part they are good quality; however, we designed our mounts for the TL to improve on some of things we felt were lacking in the TL mounts, both for the 2nd gen and 3rd gen.

The XLR8 inserts do look more beefy than the Innovative. Plus, as you pointed out, the quality of the Innovative polyurethane material was questionable and probably greatly contributed to the doughing. Whereas, The XLR8 polyurethane material appears to be tougher.
I have a question regarding that inner disc in the middle. The hole seems small. It appears that the metal dowel would have little clearance inside the hole. Would the metal dowel make contact with the side of the circle in the middle disc when the polyurethane flexed? If the dowel is allowed to rest against that disc (metal to metal), it seems like a lot of vibration would be transmitted into the car.

We were young and naive back then. The IM experience has made us wiser and more cautious.
