I just recently installed Prothane engine and trans mounts.

Definitely more solid and the vibes aren't as bad as most reviews I've read about.
I do get the feeling of low end "loss of power" but chalking that up the smoother is better. The speedo still climbs just as fast. (from what I can tell)

My question is: is the trans mount taller than stock, should I shim the bolts with washers? Ive read mixed reviews on the trans mount mount being taller and possibly throwing off the pinion angle?

Any thoughts on this?

 

If you don't have adjustable upper control arms I wouldn't even worry about the pinion angle.

 

Ok, thought I was reading too much into it. I just needed confirmation. Thanks.
