Ppf/diff brace ideas need opinions
Im going to make a diff brace that picks up on the stock ladder brace bolts (think kmiata ppf delete)
Going to be made from steel square tubing
Option 1: square tube from side to side, drill a hole in ppf, and through bolt ppf to square tubing.
Red dot represents bolt/nut
Option 2: square tube from side to side, weld on another square tube that picks up on stock ppf long bolts. Picture a "T" shape. Using the 2 stock ppf/diff bolts

They make one for NB2 as well:

Two reasons to just get that instead:
-No fab work or drilling into the PPF
-Triangles
Bear in mind any solution that braces the PPF to the subframe without bushings will induce NVH and gear whine.

Yes I've seen that but i want something more solid. I want to use the ladder brace bolts closer to the diff so the diff doesn't have as much leverage on the brace to move up/down

Im trying to solve wheel hop. Diff moving "axially" isnt causing my wheel hop.
Guess i shouldve made my title a little more clear:
"I want your opinion on going with either my option 1 or 2"

This brace also improves traction by reducing wheel hop, a must for boosted applications.
Your current design will actually be weaker. It will flex under load due to the minimal amount of attachment points. If there's anything I would suggest it's design #2 but at least with gussets reinforcing the "T". The PPF is already flexible enough as it is, no need to make it have more holes.
