Does anyone know the length of the original strut bar bolts. I've got replacement titanium ones fitted at present but need to raise the strut bar 3 or 4mm and the threaded length of the titanium bolts is only 30mm. I already have a 5mm spacer, add to that the thickness of the strut bar foot and that doesn't seem like a lot of thread left to me. Or am I worrying unnecessarily?
