After an unsuccesful attempt at using a Cusco 4 point lca brace:

I was motivated to install my Progress 3 point brace. I have had this in a box since the group buy over a year ago. Installation was actually pretty easy, since I already had the car on the lift to remove the battle scarred Cusco unit. Used a tripod to support the crossmember, and and attached the center bracket using the crossmember rear support bolts.

Kimmie took that pic laying on the floor looking straight up.
Adjusted the end links as instructed and used the new longer lca bolts and locknuts provided by Progress.

Clearance is good around my wrapped 2.5" downpipe. You can see the Progress front sway bar and lca brace almost touching the header on both top and bottom. Clearance would be better without the wrap, but it still just clears by about 1/4" on both top and bottom. I think a 3" downpipe might rub, I'll post up pics when I finish my SE-R. It will have a VE with one of Charles headers which has a 3" collector.

No chance of road interference here

Even though I sell Cusco products, if you have a B13 I can't see any reason to go with any other lower control arm brace than the Progress piece.
