hey everyone, i bought a set of FK shocks and springs for my car, i got the 45mm strut, as i thought this was the right diameter.
but for sum reason my car need 39-40mm struts, or close enough to 40mm.
has anyone ever heard of this before, and cud i buy 45mm strut holders from BMW.

anyone???????????????

there should only be 2 sizes. 45mm and 51mm. its only the 325 sports or tourings i think that have the 51mm. not sure about cabs.can you post up a pic of your strut? if for some reason you do have some odd set up im sure you could source struts from a scrappy. i think the size refered to is the size of the strut itself ,not the diameter of the insert.

i havent got a pic, but i have another pair of struts and i measured the outside of them, because i didnt have time to split it, and it was 45mm. the shocks are 43.5mm

well it seems 88 and 89 318i have 45mm strut holders, but the shocks FK make for these dont fit, there 4mm to wide, does anyone have any ideas as to what i shud do?

is it possible you have been sold the wrong shocks?

it could be but that would mean the ones i have are 325 shocks which mean there 43mm in diameter. is this the diameter of the shocks for the 325

no I think 325i shocks are 51mm
as Fuzzy stated they only did 45 and 51 mm

325s/cabs/tourings/is's were all 51mm

all other cars were 45mm

you measuring the right section?

the shocks are 325i ones thats why they wont fit too big

43mm is the diameter of the casing on the shock yes?

the diameter of a shock meant for a 45mm strut is 37mm

i measured the outside of the strut holder, which was 45.06 and 45.08 on the different ones. but its the inside diameter thats narrow. for the shocks to fit i need an INTERNAL diameter of 44mm. but with these strut holders for that to be possible the thickness of the metal tube on the strut holder wud have to be 0.5mm, which is practically paper thin.

just read ur post, so basically they have sent me the wrong ones. the downside of finding this out now is, i just bought 2 original ones to get it through the nct(irish MOT) at a cost of 75 plus vat a pop. bummer .
thanks
