I’ve never seen an air deflector for MG TCs, TDs or TFs.

If you hear someone talk of a deflector for an MG TF, it is probably for the late model MG TF introduced in 2009. Like this one:

Never thought about it before. But I could imagine fabricating one out of lexan or plexi-glass.

Attach a couple u-channels to the left and right outer edges of the seat back. The inner measurement of the u-channels should match the thickness of your deflector material. Fabricate your wind deflector, tall enough to slide down in the u-channels, leaving enough exposed to extend above the top of the seat back as far as you think you need it. (Think side window channels in your “factory built” and you can picture what I am thinking of here.)

That said…we are so exposed in these cars, and they are so NOT aerodynamic. I’m willing to bet an air deflector will have no effect on your long haired friends, distaff or otherwise! I have at times driven my TD with roof up, side curtains off, and there is still too much wind for the long haired folk.

Pony tails and kerchiefs are still the way to go!

Funny story time: When my long haired daughter was about five or six, we were out for a ride. She had her hair in a pony. For some reason, she decided she needed to adjust it. As a hearty “Noooooo….” trailed off my lips, she pulled the pony out and that beautiful hair immediately wrapped around her face and tangled itself together in a manner that took a VERY long time for me to untangle (with no comb or brush!!!). She never did that again!

One other idea, if you are installing a roll bar, fabricating a removable insert would be apiece of cake.

The guy who sold his TF (’54 TF; real TF) deflector swore it worked awesome. He’d sold the car and the new buyer didn’t want it. Seems to me it would work pretty well. The buffeting comes from the vacuum created in the space behind our big, flat windscreens. I find that it’s reduced some when I run Bridget with the small Brooklands screens up and the main screen flat….

But anyway. The deflector holds the wind above your head and moves the vacuum spot to the back of the deflector. Use it and, I’ll bet, light stuff left unsecured in the well behind your seat will want to fly out of the car. But your hair will be much less mussed. I plan on making one as soon as I can find the time.

I made a prototype of the air deflector shown in “BDrivers” post above. I tried it at 14′” above the back of the seat, then at 12″ above the back seat and then removed it and found no difference. My wife didn’t notice any difference either.

1/8″ Masonite (I believe that’s what they call it. I wasn’t going to waste a nice piece of Plexi. If it would of worked I would of bought some 1/4″ Smoked Plexi.
