Do these wear at all? The ones from my old engine are physically just fine, but does the rubber wear and lose it's 'bounce'? I don't mind replacing them if I should, but I don't want to waste $80 either.

 

not resally. the rubber just tends to falla part and break. make them more sturdy by putting calking in it. makes the car faster i swear.

 

Over time, they dry out and bake. If the rubber has deep cracks, try prying up on the engine with a bar. You will likely find that they are beginning to seperate at the bottom. FWIW, most FCs I see have a broken passenger mount.

 

The old ones are out of the car right now - along with the engine. They show no signs at all of cracking or wear. Odd perhaps, but true! Like I said, I'm just wondering if they lose their 'bounce' and if new ones would lead to much of a difference in 'smoothness' inside the car. If not, then no need to replace.

 

I'm going to be replacing my engine/tranny mounts with the banzai racing polyurethane mounts. When replacing the stock rubber with poly mounts, the poly mounts won't degrade so they'll last longer. 8)

 

tell me how they work, because if I replace banzai, i will also change the transmission mounts...

 

I'm going with the engine and tranny mounts from mazda motorsports, ~$88 for all, and 40% stiffer than stock.

 

If the mounts are not cracked or seperated, then they're fine. They shouldn't bounce very much.

 

If you want stiffer engine mounts for your coupe you can get convertible ones, they are alittle bit stiffer.

 

I'm actually getting these because they're the cheapest non-solid ones I could fine (with the mazda motorsports membership discount thing).

 

If you wanna keep it OEM style we can get you the MazdaSpeed motor and tranny mounts too.
