I have drift freaq mounts and love them so far. You'll have to see if he's still selling them. I have no idea of how else to protect them from heat, not many people online seem to talk about it. So I found my own solution, and it looks pretty clean too!
I had stock motor/trans mounts before I put on the drift freaq ones on. The stock SR mount on the turbo side has this triangular heat shield wedged between the mount, you can just take that part and throw it ontop of the new mount.
If you dont have that, I'm sure you can make your own similar metal heat shield on that side! Anything that just deflects the heat will help.
I would suggest doing this part too: I bought
these motor mount heat shield wraps (meant for a corvette?) that fit on the drift freaq ones perfectly. Then I secured them on with 2 wormgear clamps one top one bottom for both mounts.
This is how it looks on the turbo side so you get an idea, might be hard to see since I just stuck my arm down there for the pic
Hope this helps
