not true.

my '03 had 50mm. i've read posts about some cars have a 50mm on one side, 55 on the other.

you need to borrow a caliper to measure the diameter of your front strut bodies.

home depot or lowes also sells plastic measuring calipers for $1-2.

another way to do it:

buy a set of used front struts (or all four). i think i bought mine including the entire assembly (upper mount, etc) for $50. i measured those when they came, bought the konis and reassembled them. it made the changeover really easy.

you don't have to remove it. you might have to jack up the corner and remove the wheel, tho.

here's where you measure:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by flotsamm@7thgencivic.com &raquo;</TD></TR><TR><TD CLASS="quote">There are only two sizes for the front strut, 50mm and 55mm. When I questioned Koni about which ones I needed, they said that in 2002 Honda mixed them up so you could have either size and its best to measure before buying. The easiest way of the use a dial caliper like this one and measure the diameter like mentioned above:



I had one that I bought for 12 bucks from my local hardware store. If you dont have one, this is what Koni said to try:

Take a piece of string and wrap it around the strut to get the circumference. Then take the circumference and divide it by 3.14(pi) to get the diameter. Use the diameter you come up with the order the right one.

This is what I came up with when doing my math using this method:

If the string measures 157mm, then divided by 3.14 you get 50mm
If the string measures 172mm, then divided by 3.14 you get 55mm

Someone please correct me if my math is wrong thx. Thank goodness I had a dial caliper heheh. Anyways, you most likely will have the 50mm fronts. When I ordered mine from Rob at Robbear Racing he said that he never had any problems with fitment. Also I believe that the 55mm ones are the stock size in the RSX, but could have been used in some Civics.

About being loose, you could indeed have the wrong size, or it could be that you cut to much off the strut housing. The small bumps on the insert are supposed to be inside. The instructions say to measure 40mm from the top and then make your cut, like this:



If you cut to much off the bumps on the insert wont press against the inside of the housing and the top of the insert will be loose and rattle. What I did to be on the safe side is just cut off 30mm. I'd go and measure it to find out which size you need.
