Rear diffuser installation - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Has anyone here installed aftermarket rear diffusers from eBay that sell for a couple of hundred bucks?

I jacked up my car and tried to install them after I got them and I'd barely get one bolt in the top (far too close to the muffler) and then I could not get any of the other bolts in place... it looks like the bolt receptacles in the diffusers are not placed in the right places.

I drilled a hole in the bumper where I thought one was off, and then had a look at it and I don't think they're placed properly.

The eBay listing said removing the bumper was highly recommended. Now I see why!

Anyone have any pictures of how to remove the back bumper?

Randall -

I did mine, pain in the butt if you do not take off the bumper but can be done.

Also good idea to fit them prior to painting, mine required a bit of sanding so they would fit "somewhat" flush with the bumper.

Give me a call if you like, always willing to help

Well, Ive got a pdf of how to remove the bumper. I cant figure it out though, maybe you can. PM me your email if you want it.

Randall,

Just wondering where you're at on this. I thought of going this route so your post got my attention. Hope you're having some luck getting them on.

I've done nothing yet... if I have to take to a body shop to remove the bumper and put on the diffusers, I have to put it off. The BMW 545 priced renovation work I'm doing in my home is sucking all the available cash we have in the bank.

Here's a pic to show the scope of the work. Sorry for the bad shot. I cleaned the lens and it still looks like this when I shoot a dark room with a flash (anyone know what I should do to fix it?)

Bogg - I have never seen a home in SoCal with a basement. It would be awesome to have one though
