Last weekend, I put my GT3 on corner scales, and saw that the corner bias was at about 53%. I assume it would be pretty simple to adjust to 50% with the coilovers.
I’ve had the alignment fine tuned by an excellent tech, to factory specs. I’ve done a couple track days, and plan to put on Pilot Sport Cups for more track use.
How important is corner weighting to these cars? What about ride height considerations?
Thanks for any advice.

You might want to check you alignment in addition to corner weight.

When using track tires you want more negative camber. But then, your street tires will have accelerated wear on the inside.

Unfortunately, there is no alignment set up that will make street and track tires happy at the same time.

Mark, I think the factory ride height is a good compromise. Lower would be better on the track of course, but my car would scrap too much on my local street roads. My car was delivered with front ride height 10mm too high, so I had it lowered to factory spec and then corner balanced with half fuel tank and 200lbs in the drivers seat. I am not sure how badly off a corner balance would have to be for you to feel it while driving, but if you are going to set ride height you might as well get the corner balance done properly too.

In regard to alignment and corner weights, for street driving, it is unlikely that you would notice a difference. But if you are tracking the car - every little bit helps.

Also, when you have corner weights set, do it with you sitting in the car.

Have fun........

Uh, it makes a very noticable difference, plus you want to have 1/2 tank of gas at the time when you're in it-

Why a half tank? If you're doin DE's don't you normally fill up to half a tank and then wait until empty to fill it back to half? In that case, wouldn't a quarter of a tank be the right amount?

This applies to all Porsche cars:

I usually do alignements and corner balancing with half a tank

The half load of fuel recommendation is based on stints or sessions where one would not have a scheduled stop until one required fuel, run until nearly empty. It is a compromise as the weight change is a given, from full tank to nearly empty.

If you want to operate the car for shorter periods and are willing to top off the fuel frequently you can corner balance the car at some other fuel amount.
