Impreza roll center height question

[deathfrombelow]

Whiteline - I saw the graphic with dynamic roll center heights in this http://suspensionparts.info/showthread.php?t=294&highlight=roll+center+height thread and was wondering how close these numbers would be to my '05 STi. On another board, I have seen people estimate the front roll center height at about 4 inches, which is much different than your 50mm WRX. Any info will be much appreciated. Thanks.

Hi,

Thank you for your interest in Whiteline products.
These figures for the roll centre are relevant right through to the 06 model STi.
To determine the positioning of the roll centre heights we use suspension geometry software to determine exactly where they are. We have put a lot of time and effort into establishing the exact point of the roll centre and therefore are happy with the chart heights that were published.
Always a good idea to ask how they came to the conclusion that the roll centre height is at 4 inches.

Cheers,
Dave

Dave,
Thanks for the quick response. I am very happy to hear that the previously posted chart works for my car, too. Thanks!

Kind regards,
