OK, with Lovells FFL-13s fitted to my 2L engined Mk2 my eyebrow height comes in at a towering 330mm! The current Lovells catalogue lists these as "Sport Low", and at time of fitting I saw the car with so-called standard height springs, which actually raised the front end. I don't know what the free length of the FFL-13 is, but I dug out the original springs and theirs is 310mm.
Actually its not all bad in my case, as where I garage the car has a wicked slope that I can barely get over the crest of without bottoming out, so the extra height is actually beneficial. Just don't laugh too hard when you see the completed car, as it sure ain't no lowrider! One less thing for the fuzz to latch onto if they take a dislike to me too I guess.
