Hey guys, I just have a quick question. I'm in the process of switching to an m-sport rear bumper with iS diffuser. I have the bumper already, so all I need is the diffuser. I looked at realoem.com and checked the parts I need. I can see that I need the upper and lower diffusor. But I was wondering if I need the lower bumper guide as well or will my stock one work? Anyone has any experience with this, I would really appreciate the info, and it's gonna save me $18

P/N for lower guide: 51128044375
P/N for stock guide: 51127128248

They have different part numbers, so it seems like I might have to buy it, but I just want to be sure.

If there's any other parts I'm missing, please tell me. Thank you.

Exactly this ^^^^^^^

and yes, you do need the lower guide - it will be included with the kit linked above along with all hardware needed.

you will also have to modify your existing guide on PS under bumper to fit up with the new center guide. This is normal and instructions are included (just a couple cuts are req'd).

I used the exact same kit on my E92. You can get with dual exhaust cutouts and single cutout by choosing options under drop down menu

Alright, I guess I'll go ahead and order that one. Thanks guys.
