Hi, I have just ordered a sheet of 5mm thick Perspex to make myself a windblocker for my LE NA8. I was planning on attaching it to the twin hoop MX-5 Plus Rollbar I recently installed.

Here is what I am trying to achieve:
- Ease of putting in place and removing it (should not interfere with roof operation in any way)
- Nice appearance (obviously cannot lower the standard of my LE )
- Effective (so I can drive in cold weather with the roof down and not have my wife ask me to put the roof up )
- Safe (doesn't have the potential to injure in a crash)

Does anyone have any ideas tips etc.

I am trying to work out a few things. First does it matter how far back it can be. Obviously if I can place it behind the rollbar torque tube then it will be more secure in a crash. Secondly does anyone know what the optimal height is. Has anyone done a study on just how the wind flows into the cabin.

Maybe trial and error.

Maybe make a few mockups with cardboard and work out the size that works best.

Then of course transfer the final shape to the perspex.

About 250mm to 270mm should do!
I have a couple I made however the perspex is to thin, should give you a start
They are the correct width for the MX5 Plus bar
I can bring them to the Garage on Thursday or you can collect.

Here's a previous thread on this very subject:

The search feature really does work.

I did a search but found none of the design solutions worked for me even though some of them are very good and clever. I want try and hinge it backwards so it sits flat on the parcel tray, which is why I need to go back to basics and understand how the air flows and how high it needs to be. Obviously if it goes higher than a certain amount it will not fold unless it folds and drops....

what about this - any value viewtopic.php?f=28&t=38202&p=496701&hilit=windblocker#p496701
