Install them adjusted to a neutral position. Park the the car on a flat surface. From the strut bar, remove the circular end plates and install those first on the towers torquing those nuts to 34-46ftlb/47-62NM/4.7-6.4kgm. Then install the bar to the end plates, adjusting the threaded ends so the bar mounting hardware doesn't push out or pull inwards against the strut towers. Then tighten everything down in that "neutral" position. Now go for a drive thru some familiar twisties and smile.

These pics are from another thread on the subject as posted by Nd4SpdSe. They should answer any questions for a clean install.

Hey, i though those pics looked familiar :)

It's not done by a pro, just someone who wanted to install them and had some time :)
FYI, that's the Corksport rear bar

On mine it was my first actual performance upgrade. The car was still completely stock and I noticed a significant difference in cornering with the front one installed.

I will have to disagree with this statement. I have used many upper strut bars on many different cars and have found that preloading inwards on the bar is your best bet.
Remember that during cornering, most of the weight of the vehicle is on the outside wheels. Since the tire meeting the road is being pushed inwards, the top of the strut is being pushed outwards - preloading the strut bar inwards means less movement at the top of the strut.

When installing, I'm paranoid about over-preloading and affecting the camber. May be overkill but when I adjusted the bar-ends inward to tighten the bar fitment, I only snugged em as much as I could tighten by hand, and then locked the bar in place. How much preload would you say you've applied with good results? Might I not be getting everything out of these bars with my current setup?

do you drive nascar? just wondering because when you turn left, the centripetal forces are pushing the car towards the right side and when you turn right, centripetal forces are pushing the car towards the left side.

what i'm getting at is that the 'outwards' direction will change depending on which way you are turning, so a neutral preload is necessary for day to day driving. however if you only turn in one direction (ie. nascar), then ya the inward preload makes sense.

Actually, either way applies, it doesn't matter if you are turning right or left, the outside of the vehicle is leaning away from the turn (ie: turn left and the car leans to the right ; turn right and the car is leaning to the left)and therefore causing the same tire pushing in - strut top leaning out, peloading both struts inward works the same either way.

As far as how much to preload, I would always tighten by hand and lock the nuts in.

This is the best way to set strut bars.

And no, I don't race Nascar but I raced cars for seven years in the Atlantic Grand National Rally Championships and this is how everyone set their strut bars.
