Daamn, wish I had a JCW bumper on my R58s to run that diffuser lol. That looks great.

 

Instead of posting another obligatory shot of the rear end of my JCW, here's what my smooth bottom looks like. I've got both the GP2 rear diffuser and the front undertray installed, which completes the aero package since all JCWs are delivered with the panels under the passenger compartment.

I like the whole system because it's cool looking, but it certainly will help keep the winter crud off the bottom of the car and protect it from road debris - plus I think there's a little less road noise. I've also seen reports that the whole bottom aero setup contributes up to 1.3 mpg on the highway, but I think that's way too much to realistically expect.

My rear diffuser came from ECS Tuning: best price, great service, everything necessary for installation and quick delivery.

 

looks great and fully agree.

What bolts did you go with just to the right and left of the exhaust? Still trying to match the bolt on the passenger side where there was an existing clip.

 

Sorry, I can't tell you about specific hardware because I had the dealer install the rear diffuser along with a 22-mm rear sway bar as part of a package deal. (Laying on the ground under a car on jackstands in my garage when the wind chill was 10 degrees didn't appeal to me.) The only thing I remember is that ECS Tuning included 6 hex bolts with washers in its "kit," so maybe you could contact them.

Update: You got me wondering, so I just went out and looked under my car. The bolts on both sides of the exhaust are exactly the same as the two that are on each tunnel, toward the back of the car. The single bolts on each side, farthest back and closest to the bumper cover, are smaller.

 

Great setup. I've been wanting to get the blackline tail lights too! I think I'll get the diffuser first, then the tail lights.

 

Yes- those smaller bolts that go into the bumper cover are the ones. The passenger side has an existing m6 hex head. I took the recommendation from another post and used a 1/4" hex head with a slightly lager washer (and a clip for the bracket). It would be nice to know what the actual part numbers for the bolt and clip are.

 

G33KGUY - Thanks

Hey ECS,

How about coming up with a package that includes all the parts to switch over from the standard R56 rear bumper to the JCW rear bumper plus GP2 diffuser?

I have been trying to figure this out, so far I have:

JCW GP 2 Rear Center Diffuser Retrofit Kit ES#2626525 Mfg#747330558KT $260.55
Rear JCW Aerodynamic Bumper Panel - W/O PDC ES#75494 Mfg#51120404110 $217.31
Center Grid Grille ES#75526 Mfg#51120413256 $19.11
Grille - Air Discharge - Left ES#75527 Mfg#51120413257 $22.32
Grille - Air Discharge - Right ES#75528 Mfg#51120413258 $22.32
Width Extension Black - Rear Right ES#75523 Mfg#51120413250 $25.65
Width Extension Black - Rear Left ES#75524 Mfg #51120413254 $10.41
Total: $603.32

But I haven't figured out the lights and some of the trim bits. Having a kit with all the right parts would be great. Thanks in advance.

 

Hello squaWSkiBum,
There is a little more into it. Dependent on year options / Rear fog lights or not / rear back up light or not. Painted arches so you can get the primed lower trims. And the year / model and then the hardware. Shoot me a PM and I can help you out with options and what you want.

Thanks

 

I just installed mine too, it took less than an hour. The hardest screws were the 2 on either side of the factory middle section. There is a Youtube video that helps explain it.

 

Installed the diffuser on my wifes JCW Roadster two weeks ago. Completely changes the look of the rear end.

 

Rum4 - post up some pics. Really look good on the roadsters.

 

tigerwong58,

The rear diffuse really looks great, nice strips too...

 

Yes the rear diffuser looks great on the roadster. But I forgot how bad the stock tails look. Find a picture of the Blackline rear tails. I'd post a picture if I had a good one, but I do not. OK just took a quick pic in the dark to give you an idea. Looks great on a midnight black roadster.

 

Have the same lights on my black R58, worth the bucks.

 

Where could I find an assembly instruction (pdf file) for the GP diffuser?
The local workshop would not put it on without instructions..

 

I did mine watching the YouTube video.
It's straight forward. There was no PDF when I bought mine from Outmotoring. Just share the video or find another shop.

 

Just finished watching the video, can you tell me about what the time-
frame was for the installation. Thanks.

 

I backed it up onto ramps, and it took about 45 minutes, it took the longest for the 2 original screws on each side. Also when installing the diffuser make sure all the tabs snap in. For the 2 brackets, just bolt them up first, there is no movement or adjusting with them so it's OK to tighten them up.

 

Thanks much!

Question on the the front GP 2 Belly pan retrofit kit. Does the entire panel have to be removed every time you do an oil change? Thanks!

 

Yes, unless you drilled a hole right where the drain plug is. The Belly pan only takes a minute to remove though so it's not bad.

 

Hello Champ.

Yes, and its easy. Take a Phillips head screw driver, hold the center of the very light plastic belly pan with one hand. Then with the other hand and tool work your way around the speed clips are made to come out with about half a turn. So you are not holding the pan and constantly turn a long screw. Lift the back down first and the front pulls back a inch out of the bottom and it comes out. Install in reverse. All the speed clips and hardware will stay in place as its retained on the pan, so no screw to drop or anything.

Its a really slick belly pan kit.

I have done many oil changes with mine and no problem.

Hope that helps.

 

Thanks for the quick response to Way Motor Works and ECS Tuning! Great vendors!
