Austarion

does anyone have a removed insert, I need to know the compressed and fully extended length's in mm please

Dont know why you asked, but I can tell you that a Skyline/Pintara insert is 40mm shorter in height and has piston stoke that is 35mm shorter again. So if you remove 40mm from the strut leg, just below the insert lock-nut thread and slip in the Nissin insert, you have around 70mm less suspension travel to help if you want to mess about with shorter springs.
And the Starion top mount bolts straight on.
Got this setup in my Sigma.
Then again you probably didnt want to know this anyway :?

I work for pedders and could match up inserts from the sports range and offer them cheaply to club members

Here are factory Starion Specs:

good work will get back to you all soon with options
