Our cars are old and most of us have boosted the power and stiffened the suspension to some degree so I think anything that helps improve the chassis rigidity has to be a good thing.

I'm no expert but I would go for one. Haven't got one yet though
Funniest thing I have felt is when riding as a passenger in my car at Wakefield Park - when cornering HARD, I could feel the floor flex near the firewall Booong - floor pops up, then booong - floor pops down! Really weird I also agree with the 'opening' door frames when cornering ..... could hear the wind whistling through it on a windy day at Wakefield

no thanks, ouchy

mine took off .75 of a sec on the quarter mile!

no but seriously... rally cars have tended to cave in at the front over time due to small jumps encountered

so in that case the are very helpful

otherwise what other people have said, aguable amount of stiffness added to front

I made a very sturdy steel strut brace for my old coupe. Could not feel the difference when I fitted it at all - either before or after the cage went in. Its the only "suspension" mod I've ever done that had zero effect. And I've done silly little things at the track like loosening rear sway bar link pins 2 turns to help correct an oversteer problem - and you can notice something as small as that!

Strut braces? can't hurt, but probably don't help much either!

My 2 cents.........
Horses for courses.

I reckon a bit of body flex isn't a bad thing.
However, If you're regularly pushing hard then the constant flex can result in the chassis welds being fatigued. Possibly resulting in structural failure. $$$$$ Ouch!

This is where a strut brace comes in........
But. (there's always a but) If you're running poor quality suspension setup, I reckon a strut brace accentuates ordinary suspension performance by taking the flexibilty out of the chassis & forcing it through the suspension.

If you're racing regularly or just like a bit of bling.... Go for it, but I reckon they're not necessary for normal street use & the occasional track day.

i had a mate who fainted at the wheel and wrote of his 1600. He hit a brick fence with the front corner and the car crumbled but the strut tower brace held its own. Safety too! what more could you ask for?

it's not so much weakness in the strut towers that'll let them flex its the chassis ... or lack of in the case of a datsun ... that allows the motor to twist the body so much ...
all big hp cars will suffer from chassis twist under a big launch/acceleration, watch with drag cars, generally one wheel will lift alot higher that the other depending on chassis strength, the addition of a tower brace may help in the situation but they were originally designed as a suspension component not a body strengthener

I will have to go with Pierre with this one too. A racer friend of my dads told me the same thing about a tourquey motor distorting the strut towers.
I dont know weather my car will have any problems with it but I have made one up just incase "read 'showpony'".
It is made from two Falcon torneu? cover holdy upy things, so it has a nice curve to it. Ha, as soon as my engine bay starts to twist, my welds will probably all give way

engine bay bling my shiney ones are anyway

if you are pushing your car that hard thru corners with a damn sticky tyre, and still managing to keep it on the road, you may notice a little difference between with or without, if you rally and jump your datto regularly you may also notice a little less inward flex of the towers, and your alignment may last a little longer.
the firewall and the bulkhead will take the most of the twist ... how successful this is also depends on how much rust you have in the engine bay
