JCW jcw gp 2 diffuser
#126
I believe there are 8 screws that are mounted into the tunnel brackets (4 in each) There are included in the kit. There are those 6 additional threaded clips on the other end if the tunnels brackets that don't have screws (2 on the metal and 1 on the plastic of each piece) that we seem to be short. I don't have a part number and I believe the screws that were given by the mini dealer to the one guy who installed it were not the correct screws but they seemed to have fit.

I forgot all about those four holes on the very end of the metal piece because I don't have that cross member on my 2009 factory JCW. Those four holes are not attached on my setup. I was talking about the 3 holes on each that screw into the bracket. I wish I had that cross piece because it does indeed look like you reuse the screws from there to bolt the very end of the diffuser to the car.

the rear part of the muffler (cat back) has a hanger on each side that attaches to the chassis with two bolts. You can see them in the picture above where the heat shield has the two cut-aways in the middle. You undue the bolts, slide the bracket underneath, and re-attach the bolts. I did each side one at a time, and I was laying on the ground. It will be much easier up in the air. It will all make sense when you hold them up there. Just use the right one on the right side - left on left. I made sure I matched up the part nos. correctly.

If you look at the picture above on the Roadster - there are braces that come from either side and meet just forward of the muffler. They meet on either side into a rectangle piece that has two screws on either side. I don't have this piece or that bracing on my hatchback. I think it may be bracing for the Roadster because it has no roof. It looks like the rear two holes on each tunnel may screw right into those using the existing screws in the chassis.

I've had my 2009 JCW on a lift before and as of kfmuller confirmed, the cross braces shown on the Roadster above are not there.
Maybe the GP2 has the necessary bolts underneath the car already attached to something. Doesn't it also have flat panels running under the car to smooth out the air flow making the diffusers more effective?
Just making a guess as to why the necessary bolts are not included for some reason.

That explains the two holes on each tunnel on the very end, but I'm not sure why they didn't include six more screws that attach the tunnels to the brackets and screw into the included clips. However, since you can take a clip and a screw and get something from the dealer or hardware store that matches the screw in length and that will thread into the clip - it's not a big deal, and ultimately, a really easy install.

Of particular note to me is the Skid plate like ground effects up front. I've glanced over realOEM without luck so I'm not sure if this part has made it onto the production GP's or not. Pretty cool.

Here ya go! I grabbed these from a MINI promotion video for the GP after its reveal. Their not the greatest shots but might help a bit.

Just wanted to attach this image (posted earlier in this thread) that kfmuller used successfully in his install.

I'm no aerodynamics engineer but I don't think performance would suffer as a result.
You can buy the under panels though from Mini if it's a concern. They aren't new as a part of the GP, they were originally included as part of the Aero body kit option (not the JCW body kit).
From what I recall they're not expensive and it's also an easy install.

I think someone should email MINI asking them for installation instructions and what screws should be used to mount the tunnels and the brackets. The person (probably customer service) might not know the answer, but see if they can forward it deeper internally to the department that deals with parts. It seems like they forgot to include additional screws.

I could certainly be wrong but I know of two individuals who've tried to order these through their dealer and when they input the part numbers it required at GP2 VIN. The GP1 did require a VIN number for exclusive parts. MINI may intend to sell these parts to whoever wants them. Lets hope so but I know BMW's logistics system is a huge lumbering beast and it may just take time for them to catch up with it.

I picked out a few. Could it be anyone of these?
