Well it was nice out today so I got motivated and installed them in the driveway at my parents' place (Mom parked her car in the garage so Id fix her air shocks before I worked on my car again, sure outsmarted her hehe).
The height is about the same as my solid rubebrs were, maybe just slightly shorter, which is good. There's no problems with being a little shorter, in fact I think the stock mounts are a little shorter than the solids. Anyway, I started her up and it idles great with solid mounts, kinda lost some of the cam lope though
I yanked the throttle bracket a few times and the engine doesnt torque sideways at all, but it vibrates slightly when at idle. I took it for a drive, when I first sat inside with it in park it vibrated a little. When I put it into drive it rattled a lot. I can hear some of the dash brackets rattling around. The off-line response has improved greatly. Once the rpms are up a little, probably around 1000-1200rpm the vibration goes away for the most part, but you can still feel it.
I called Julian (T-bird4vr) over for a second opinion, took him for a test drive. He said he wouldnt get both mounts for his car, but possibly the passenger side one (which is cushioned more, as seen in the pics above) and that he wouldnt put them on a stock car if you're just upgraded because your mounts went bad, the solid rubbers are a good choice for that. He also said he wouldnt use them on a lightly modded car either, they feel great for a highly modded car though, street or track. I agreed with him.
So the concensus is, dont get these if you like a smooth ride, and dont get them just to replace your bad ones. Get them strictly for performance reasons. It might be a little more tolerable with just the passenger side, so I'd reccomend a rubber driver and this alumi/poly for the passenger side if you're looking for for streetability with a bit better torque response.
I'll keep marking my experiences with them for a few weeks to see if I get used to it or change my thoughts or anything. But these mounts are awesome in my opinion, I like them a lot, great design, great quality, very durable, and great improvement on torque response. When I get my 3000 stall converter I'll see how they do then too
and on a side note
- Julian returned the favor by giving me a ride in his car
He just installed the smaller pulley and raised top on his autorotor and is pushing about 18psi now. I seriously dooded my pants, he floored it and the 225/60/16 tires actually hooked, surprisingly, and I my cheeks touched my ears. I couldnt move from my seat. Deffinetely has mid 12's in it.
