How much Noise should the TOP make?, Rub'n, shift'n and mov'n all of the " 'ns " Options

All Teeners,

Focusing on the things that bug me.

When driving down a bumpy road (which is every road in the Boston area) the top makes a great deal of noise on top of the sail.

I have all new 914Rubber front and back and all over the car BTW.

I have tightened the latches as tight as I dare.

Both doors are tight and fit well. I also have added Brad Meyers tub stiffness: https://914ltd.com/product/porsche-914-chas...-repair-panels/

Perhaps a few thoughts as to how to test for body flex longitudinal? Might this be the culprit, twisting???

Thank you,
CTC911CTC

Too high of expectation

These are not modern cars.

As previously stated by Mark, Silicone Spray and Armor All can help. Krytox is what the auto industry uses on certain problem areas like windshield surrond trim and what will be most effective of the targa rubber to body interfaces. There are all kinds of grades of Krytox ranging from

to more OEM versions that cost up to $100 for 2 oz but it lasts and it works and 2oz will do hundreds of cars.

If you really want to eliminate all squeeks and rattles, you're going to have to buy either NVH felt flocking like this

or anti-squeek polyethylene tape

Use at interfaces between trim parts that can move relative to each other.

If you've ever worked on a modern Japanese or German vehicle you'll have an idea of where this stuff goes.

Superhawk (Studebaker guy?) thank you!

Seems that both you AND I have too high expectations. How else would you know about all of these great remedies?

I will try them this weekend,

Thank you!

Nah, my expectations for 914's are pretty low. (IMG:style_emoticons/default/happy11.gif) But, my love of my 1st 914 and the time I spent working on it in my 20's is what motivated me to become an automotive engineer as a career.

I've spent way too many years of my life working on things like NVH, water leaks, powertrain noises, etc., but it has been a fun ride for the past 25 years. (IMG:style_emoticons/default/biggrin.gif)

We'll see how much longer I can go, but I supect the panicdemic is about to kill the industry along with many others that have already lost their jobs. (IMG:style_emoticons/default/sad.gif)
