I just called and spoke to a Brey-Krause Engineer about my car and what parts to order, he recommended the following for an e92 m3 with driver's side Recaro Profi XL.

harness bar - r-1203 x 1 total
sub mount - r-9258 x 1 per side (not on website yet but recommended vs 59 part no.)
seat mount - r-9281 x 1 per side <-- even though Profi XL states 430mm it tapers at bottom so this is the recommended mount
harness lower clip ins - r-9289 x 1 (driver side part no)

harness lower clip-ins - r-9288 x 1 (passenger side part no)
