Gap is too wide to make it worthwhile. Can be done but not optimal.

They're too small gap is too wide to weid.. They're heavy but I'm guessing people do it.

I'm pretty sure the shape has a subtle difference too than a roof sans sunroof so they can tuck under. Very subtle though. I can check this and confirm.


The way to go imo is with one of the stamped panels using

*3M impact resistant structural adhesive (3M-07333) $65) which you can weld set in place also.

Then you heat it to 80F and it sets in 30 minutes. Stronger than welding.

Front and all rear glass out, door glass stays put.

Tape off glass openings.

Then with finest flap disc remove paint on roof and down the A and C pillars for blending paint. Feather paint edges toward glass opening.

Fill roof seam, sand, repeat, feather it out (PITA) and shoot epoxy primer once nice and smooth. Use light and guide coat to check. Allow days to cure (shrinkage) repeat.

Then fill primer and start sanding again until you can paint and blend color coat and clear halfway down the four pillars.

Drilling out the sunroof assembly and installing the panel are the easy parts imo.

Then you need to reinstall the headliner which isnt too bad.


Good luck!

Matt

I struggled with this during my build. I love the clean look of a deleted sunroof, but I couldn't get rid of it. I like the option to open it once in a while. So I ended up keeping mine.

Seems like a ton of work to make your car look almost the same. I think with sunroof delete some value of the car is lost. Sunroof is nice on a warm spring day. But then again, I like my sugar scoops just fine.

Agree,

I asked a very intelligent, well regarded and well known in the Porsche world..75 year old ex Holbert's and Brumos racing mechanic (with many SCCA trophies) what he thought of sunroof delete on 911s.

He said; "noone uses them anyway"

He owns several 911s and maintains historic factory Porsche racing cars for a living still.

Case closed in my book.

I never used mine, and if you do, it is simply a small hole in the roof not an open air vehicle. The damned little felt strips were also a royal pita after a time.....and...the big and...I had to look at the damn thing that ruined the cars lines every time I got into it not to mention that is the dumbest place in the world for weight in a sports car...as high as one can get.
It also reminded me of the Euro's concept of what Americans want....superfluous weight gain.

Other than that they are fine

Actually...a little here....a little there...and strangely enough it has lost about 400 lbs....
Holy smokes! Fully wet....500 dry....if that is meaningless to you then cruise on...

Just saying a 2014 Subaru wagon is still faster after all the effort. The roofline looks the same with the sunroof , A Targa does not.

Objection! The roof-line does NOT look the same. Also, subaru wagons 2010-2016 show 0-60 to be around 10 seconds.

2016 Subaru Outback 2.5iⓘ
9.30 sec 17.20 sec


My base model 911 with no mods from 1975 is faster than that. :-)

don't overlook what the lack of a sunroof does to the lines inside the car. if you don't care, that's just fine. there is a considerable difference in a car with no sunroof aesthetically, performance be damned.

but i'm biased, and i'm removing the sunroof from my '74. that car should weigh around 2100 lbs when i'm done with it...

I love my 85 911 and the way it smells and drives and corners. That is why I have my car. I’m just saying that removing AC parts, sunroof delete, back seats will just not make your car that much faster . And when it’s selling time, and we all sell in time, buyers just may want all that stuff. I sure would on a Porsche classic. Why do all this stuff when a mustang GT with 460 horsepower will
Pass us like we are standing still.

Now Now boys, didn't mean to strike a nerve......

I appreciate all the feedback. I'm collecting parts to do a 74 RS (IROCish) conversion on my recently acquired 86.
I expect the sunroof will go away and it looks like a formed panel with 3M adhesive will be the path forward. We'll limit the welding to the 930 flares recently purchased from another pelican member.

When completed I'm sure this will be the slowest car in my garage....but I expect it to be a pleasurable driving experience,

Nick....it is like a fat guy losing weight....being nimble...digging out of corners....much better feel and responsiveness...
No one ever bought a 911 for 0-60...surprised one has to articulate that...as to selling...I could care less about that...but all the parts are stored...but, I really don't care...again, I didn't buy it for resale. I'll probably give it to a nephew anyway.

Hey looks great! I'm about to have my bodyshop do this to my '82 SC. I was going to get the Rennline panel (here) but I'm struggling with what is needed in the headliner area.

Do I just need new headliner for cars without sunroof (obviously), and then the headliner rods sold by Pelican (1 through 4?) and the accompanying rubber ends? Do I need new headliner clips? Anything else?

Thanks!
