Great, you are welcome.

Wanted to make sure you have enough.

Post up some pics when you get it all done. Very nice looking mod.

BTW the R59 looks great.

They will fit, at least, an R56 without the aero kit. I put them on mine before putting only the aero bumper on. Hope that helps.

Does the 2013 R56 JCW come standard with the underbody panels?

Honestly, I'm not even sure if that panel made it on to the final version of the GP2 as you can see the car in the pics/video is a prototype with camo, etc. and even the diffuser panels lack the aluminum bracing parts showing up on the final version of the car. My parts dept. guy has his eye out for this piece and if I hear anything I'll certainly post it.

As for the underpanels, they are a cinch to install. My JCW Coupe came from the factory with them installed but I've removed them several times to work on the car. It can be done with the car on jackstands. I've even done it with the car on the ground and my Coupe is lowered though it was a pain feeling for where the fasteners go. Once you slide the panels in place they screw to the underside in several places with little square headed plastic threaded fasteners. I believe a 7 or 8mm socket will do the trick. Don't quote me on the socket size though since it's been awhile since I've done it.

Glad to hear. The GP2 diffuser should fit nice.

It's high time for me to try this mod on my R59. I've had the GP2 rear diffuser installed for over two years and just recently discovered that the upper side of the diffuser is a collection point for stones, sand, and even standing water. I'm thinking the side panels and front belly pan would help mitigate this, along with the other obvious advantages.

For the side panels, is there a break-out anywhere that shows which fastener goes where around the perimeter of the panel?

There is a diagram on the first page and then they talk about the mod.

Here is the link to the diagram and the # corresponds to the locations of hardware.

Much appreciated. It's not very specific about the 10 cap nuts per side...I suppose one just looks for the logical locations of the studs.

All of the right-side panels showing as discontinued is a bit confusing.

Yea, the screw nuts just mach up to the studs already on the underbody, peak your head under the car and you can see them.

The left and rights are available.

They SS to R56 parts to the R58 parts for the main panels . Here is the part for the R56/R58 models. ( * To fit to the R59 model )

OEM MINI Part nubmers : 51752759385 & 51752759386

Gary, Did you survive the Iowa Winter ok this year? Down here in Des Moines, we didn't have much of a Winter, really. A couple of snows, one in the 7-10" category, a few days of cold temperatures, but our Lil Guy trucked on thru. Yes, I drive it everyday, it's my transportation to and from work, so it has to go. It's never really bad, as I live only 1 1/2 blocks off of Grand, and that is one of the first streets cleared completely in the city.

Two weeks ago we had a sampling of Spring and today it's suppose to be 70, so the top may come down on my way to work at 2:30. It's already feeling nice, so maybe that top may come down sooner than I thought. Keep in touch, and have fun with the r59.
Bill

Which part number is for the passenger side? It only says left or right on ECS. Im not sure if left is passenger or right is passenger.
Heard a loud clunk on the freeway today. Jacked up the car and found a nice crack and a hole on the passenger side underbody panel. :(

Thanks

One more question...how does the side panel fasten to the rear diffuser?

On the first page of this thread pics are posted with the GP2 rear diffuser and the JCW underbody panels.



Thanks

Yes I've studied that pic, which shows what is apparently a metal-head fastener through the inside diffuser mounting point only. The RealOEM diagram isn't any help, as that fastener doesn't seem to match any of of the listed selections.

There are main screw to hold it on with the bracket. Then trim comes preloaded with black screws.

http://www.ecstuning.com/Search/SiteSearch/51747330558/ES2626525/




Looks like some people are using other screws to front section. But some guys are not doing this because the main 6 bolts and other preloaded screws hold it on.




Might want to ask Blue Toy ( Steven ) he posted on the first page.

Thanks

I think I solved another pre-installation mystery that's been bothering me. The OEM diagram below shows the two small asymmetric brackets (Item #5 for the right panel) attaching to the panel with a hex bolt (Item #7)...



...but the brackets I received didn't have have a hole to accommodate a hex bolt; instead, they're just like the previous pictures in this thread with a welded screw post on the bottom...



I thought perhaps that the brackets might have been modified since their inception; however, the OEM part numbers appear to have never changed. Anyway, I'm deducing now after a test fit that a couple of plastic nuts, vice hex bolts, should be used to attach these brackets to the panel (and I have a couple of spare hex bolts that I don't really need).

Finished this install on my R59, including the GP2 Belly Pan. I'd post pics but they'd essentially look identical to BlueToy's (appreciate his path-finding for the Roadster adaptation).

Other notes:

I used four stainless steel fasteners to secure the rear edge of the side panels to the rear diffuser. Just seems to make it all more solid.

I'm not completely happy with the two rear speed screws on the belly pan. They just don't have that satisfying lock with the final turn. I'm going to try new clips and screws to see if I can get them to behave better.

In retrospect, it was easier than I had anticipated. A lift, vice doing it with jack stands while laying on my back, would have made it even easier.
