I was wondering if the factory rear quarter windows on cup cars (997.543.112.90/PC) are fairly easy to get in and out. I would like to replace the glass quarters in my 997 GS car with something that I can pull more easily when I need access to rear suspension etc.

Thanks in advance!

Literally pop them out at any point - three round ends on the back side of the window that just press into rubber gaskets on the car. You'll be amazed how easy they are to remove and install.

Actually when you see how easy they come out, you will be afraid they will come out on you sometime. They wont. But boy does it make getting into the back of the thing easy. Changing suspension settings and removing rear shock is now stupid simple.

Awesome - thanks for the feedback.

If anybody knows of used/spares people want to sell please let me know before I order from PMNA (not inexpensive parts but not unexpected price either).

You are better off going new as these scratch easily. Another source I've found is plastics4performance.com

They have different thickness as well as color options as well as hardcoating to prevent scratches.

If you have street doors and glass I'd measure thickness so you can order a thickness to match So it's uniform still.

Thanks bmwtye - I'm only looking for the rear quarter windows that can be easily removed which is why I was looking at the cup parts. Plastics4performance would definitely be the less expensive option for non-removable for sure.

They have those with vents and without vents. I've talked to them about it and they install and remove just like the cup ones.

Great - thanks for the clarification. I'll reach out to them.

Exactly. Had me wondering if this was all gonna stay together next time I threw the car into T1

Be careful when you slide out / reinstall the window tho. While the rear part's secured by that half-screw going into a rubber grommet, the front has a metal tongue that slides into a bracket on the tub's B-pillar. Slide window towards the back of the car to remove. Don't yank it away from the tub... that metal tongue is *barely glued* to the underside of your lexan quarter-window... snap/break that and you'll have to resort to epoxy glue... wonder how I know huh...

Let us know what thickness you get and whether or not you got the hard coated.... I'm curious about this as well for no other reason than the suspension adjustment ease if its really that easy to pop the side window out.

Thanks for the tip CRex - we all learn from our...well...mistakes :-)

Blue Chip - will do. I am going to post a WTB for the Porsche quarters to see if anybody has a pair collecting dust. If not I"ll go with tye's recommendation.
