Hopefully they lowered the rear perches! I just had to take mine out and move them! Im on Eibach but 26 7/8

also curious how much lower HR is..I’m also on winter wheels/tires that I believe have a smaller overall diameter than stock. Maybe measuring from center of wheel to fender might be more accurate?

Mine is at 27 1/8 in the rear from top of the fender to the ground with H&R springs on the lowest perch, 26 3/4 in the front.

Rear gap before on h&r springs with the perch at the highest setting was around 27 and 5/8ths inch. Afterwards on the lowest spring perch setting it was around 27 and 1/8th (1/2 inch lower). I did find a capristo carbon fiber diffuser for the 991.2 gt3, however it was like $2500...really didnt want to cut that one up! The oem can be had for just over $500 from www.getporscheparts.com (which by the way was AWESOME to deal with). Jason @getPorscheparts went above and beyond to get me taken care of and the product shipped right away!!

Update-I was able to take the car out this weekend to the DRT cars and coffee in south Florida. I attempted to get some pics of the diffuser but it’s REALLY hard to get a pic of it to show up under the car. Here are my attempts-but I can say it looks really good and subtle IMO

Also, I made an extension out of carbon fiber and mounted it up to give it some extra flare. I like the look and think it flows very well. Here are some additional pics




Tried at night with some light on it.

Looks awesome. Congrats.

The extra CF piece looks super.

Diffuser sure looks low. I cannot get away with it here in NY with all the potholes and speed bumps.

Thanks, yes it for sure the lowest part of the car for me. Thankfully I have not bottomed out over some large bumps and speed bumps as of yet.

Just took some pics-looks like at the lowest point it’s about 2.5 inches off the ground 😬

Here’s some additional pics of the carbon piece I added to the center. It’s a pair of carbon canards I had for my gt4, and I used a sheet of carbon fiber to join them together with rivets. It mounts to the stock center faster on the bottom of the bumper and on the other end it’s mounted to the 911r diffuser with a nutsert


The gap in the middle is where the oem muffler sits

Another angle

Test fit

One more shot showing the profile from the side. It matches up great with the contours of the 911r fins
