rhyso...so what you are saying is that the ultra lows will be super lows on the std falcons but ultra low height for XR series?

i think he means that if you ask for superlows for an XR they will actually be ULTRA LOWS .... and superlows for std faclcon will be SUPERLOWS. (if you ask for LOWS for an XR they will be SUPERLOWS... based on Rhyso's post)

i dont think this is right.. i may be wrong.. but i always thought that superlows are superlows no matter what car they are for.

kings measure ride heights from centre of rim to guard. superlows are around the 345mm. this means that regardless of where the car sits in std trim it will be around the 345mm with 'superlow' springs fitted. so if you lower an xr or xt they should be about the same once lowered, give or take usual tolerance.

the above comments are an example and not the actual measurement for all cars. 345mm front and 350mm rear is 'superlow' for eb. most e series are the same but can't confirm this plus all cars react differently.
