Right now, I think the fact that Xtreme doesn’t require heat to install may be enough for me to go ahead and try it out. Thanks again!

“…The Original kit offers the best value for the money. The Xtreme kit controls vibration four times better than Dynamat Original and requires no heat for installation. Self-adhesive….”

1. The vibration dampening performance of Dynamat Xtreme is about 4 times better than Dynamat Original :

Original:
“…The theoretical maximum loss factor is 1 (no vibration). An undamped 1mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynamat Xtreme applied to that panel would increase the loss factor to 0.417 @ +68°F…”

Xtreme:
“…An undamped 1mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynamat Original applied to that panel would increase the loss factor to 0.14 @ +50°F…”

2. Bonding strength of Xtreme is about five times better and requires no heat to bond well:

Dynamat Original Adhesive Peel Strength (Bond strength):
8.6 lbs/inch (15N/cm) on cold steel

Dynamat Xtreme Adhesive Peel Strength (Bond strength):
42.6 lbs/inch (74.8N/cm) on cold steel

3. Thickness is about the same but the Xtreme weighs about 33% less than Dynamat Original.

Unfortunately Dynamat hasn’t listed any technical specs on the Superlite yet. I’ll probably use their Dynaliner product over the trans hump for heat reduction. I haven’t been able to test the performance yet since I haven’t started the car since the Dyanmat was installed. As soon as I get it on the road I’ll definitely give an update on the performance. Hope this helps.If you have any more questions, let me know! Have you been following the site for a while or did you just stumble across it?

It’s definitely rising from the ashes alright. Slowly, but it’s getting there. I at least hope to get it to a cruise-in this year. I know I probably told you the same thing last time we talked forever ago, hah! I certainly appreciate the encouragement. Get me some pictures of that car of yours. And get started on it already!
