Saw the part from Suncoast in their Sunday email. They don't list a PN, wonder how it compares to the part listed as $250 above...?

I plan on adding this R diffuser to my GT3(suncoast version), even if it doesn't add downforce, I can't see it pulling any downforce away. So for me I'm going for a visual look, I think chicks will dig it...In a Joey from Friends voice, "hey baby, you see my fins under there?" lol

The GT3 needs more rear downforce. I'm not sure how functional the R diffuser is but I'd say go for it.

Looks and more importantly functionality

I agree that there would be added functionality.

Dealer made a correction on the 911R diffuser quoted pricing. It is $795.00, and not as $250.00 as I suspected was in error. Sorry guys on the incorrect diffuser pricing.

Looks like the Suncoast pricing is cheaper then at $559.95.

Anyone has a picture of SunCoastParts' diffuser installed on RS with opening modification yet?

I think at the least, it will clean up the air travelling underneath.. Unsure if anyone could actually feel a difference, unless at the limit of grip.

I've offered back to back testing at Sebring tomorrow through Sunday, but no go.

Why will this NOT fit on a standard 991??? .. I need this to protect the engine pipes and pan from dirt road stones and curbs

how does it attach? look like a easy mod to get it working on a 2012 991 C2

Not a RS but on my GT3. Cell phone pics, sorry. Had to cut out for the PDK, it was a pain in the a** but I'm happy with it. Haven't tracked it since the install so no feedback on if it works or not with helping the backend being more planted.

Also, if you have long tube headers, you will have to trim a little around the front pipe area. These pics are with my old catted headers which were fine, but since installed LTH.

Joe731 has the 911R diffuser on his RS....PM him and I'm sure he can send a pic

Wonder how well it would work in conjunction with sport design duck tail cars etc. ?
