Koni Question

[EducatedFool]

Hey, I'm about to buy some Koni shocks. But when I checked for part numbers on their site, it says they come in 2 different sizes. What's up w/ that? And how can I tell which size I have? btw, i drive a 91 318i

Check the OD of your front dampers they will be either 45mm or 51mm.

Only the m10 318 and a handful of early etas had the smaller struts, we all have the larger. Always worth double checking of course if you can.

Yea that's what I was thinking. Where are you ordering from? Just tell them you have a 318is that way there's no confusion in which of the 318's you have (m10 v m42)

Not all vendors are familiar with the variations in the cars hence them putting the final decision making on you the end-user to avoid any "errors."

i was looking @ the Koni website when the confusion came up. I'm order from a friend of mine, getting me them for a steal :D

Smaller struts are on all 318i/316i and some 320i here in Euroland. Ye westerners didn't get these!

You can really feel the difference when driving above 160km'h for a longer time. The 45's will act badly compared to 51's... At lower speeds, the difference is unnoticable.

I had 45's as I've bought my car 318i and replaced them with 51's after few months.

I've checked both on KONI shocks... After replacing them, be sure to put them in the pipes flooded with oil to let them cool better through the walls.
