I want to remove the windscren on my MGF, but its been suggested that there is a lot of torsion strength in the screen, and that I should leave it in situ.

Any thoughts?

I will be adding sone of the later MG TF torsion bars under the bonnet, over the engine covers and between the tunnel and dash

I would have thought that a decent cross brace between the bases of the a pillars would be enough to equal or even exceed the strength of the wondscreen then any additional triangulation would just add even more strength.

However, if you;re trying to save a load of weight by removing the screen and associated bits (wipers, motors etc.) then you need to consider how much steel you want to add back into the car to make it worthwhile bothering.

Yep, the weight saving is the thing, but also I want the car look different as well.



this look would be nice

make sure its swedish steel !!

windscreens do offer a lot or torsional rigidity , but its only attatched at one end .

Do you have a midget yet, as Jacko's old one was still up at Owelly's last time i looked.

Modern cars use the screen as a stress member. Thats why they are bonded in to the shell.

I once heard it said the screen gave 40% of the torsion strength to a Sierra.

That quote maybe horlicks but I understand the bonded in principle of screens on modern cars.

I can understand that for a tintop, but was not sure how muchif any on a convertable.

Its only attached on one edge.

The side windows kinda just lean against the window rubber

Was hoping everyone would say chop it off cos its not needed.

Where can find how much, and if i replace it with fitting stuff elsewhere?

My Midget is off to it's new home next week!
Just chop the fekin screen off and worry about the rest later.....

how did i know you would say that.

anyway, do want to borrow the mg now its running?

I say just go for it, but it's not my car to take the risk on. Though I don't believe the screen adds much if any strength to a convertible, certainly less than a properly executed strut brace.

Here's a similar look in a spitfire.

Yep, i'm liking the look.

Its only a £400 car anyway.

I think I post something on the chassis part of the forum and see if anyone suggests bracing points.

The core MGF body structure - largely shared with the later MGTF. The green areas are the sill, A- and B-post structures that are key to the whole body's strength in torsion and bending. The yellow-coloured windscreen rail also plays a role, along with the bonded-in windscreen itself (not shown).
