Compressed 480mm
Extended 685mm
Strut diameter 38mm

Thats from centre of lower mount, to end of shaft. So take off 30mm, and that should be about where top nuts retain upper washer.
I'm not much good at converting mm back to inches, I should get one of those tape measures that has both!

Not super-difficult, divide by 25.4, or just 25 for ballpark numbers.

I cant think in mm, always need to convert it to inches. Just like i cant think in celcius above 40c but farenhight means nothing to me below 105.
I have started using a unit converter app on my phone a lot since joining this site. Im starting to get a rough idea of how fast mph is now after a year and a half...
The coolest tape measures are the ones that are already in fractions for the inch side.

That part is fine. It's more the conversion from decimal back to 1/64ths. I'm pretty sure you need a Sumerian abacus to do that.

Thank You Sir!

Nope, that's easy too. Multiply mm by 2.527 to get 64ths of an inch (or just 2.53 for a close estimation).

Here's why:
1 inch = 64/64ths inch = 25.4mm*, all interchangeable for math purposes

So, to convert 38mm to 64ths of an inch:
38mm / 25.4mm = 1.496 inches (call it 1.5)
64 x 1.5 = 96.0
So 38mm = 96 64ths of an inch, because 1.5" = 96/64

So, using the shortcut:
38mm x 2.53 = 96.14, or 96.1 (remember this is .03 high)
So 38mm = 96.1/64ths; or 96/64ths, i.e. 1.5 inches

What I would do if I wanted to get it exact and had to multiply it in my head is this:
Multiply mm by 2.5 to get close, (38 x 2.5 = 38 + 38 + 19 = 95)
then multiply the mm by 1%, (38 x .01 = .38 )
triple that, (.38 x 3 = 1.14)
then add it to the result of the first answer. (95 + 1.14 = 96.14)

* slightly inaccurate

Tom, there is a special place in.......reserved for people that smart
and you did that in YOUR HEAD ?????

What, you thought I was just another pretty face???!!!

The last part (38 x 2.53) I can do in my head in about 5 seconds. but all the rest I used a calculator to work things out. I ain't no autistic savant kinda guy, just decades of familiarity with arithmetic. 38 x 2.5 takes me less than a second; the other 4 seconds are for the .03, because of the eight steps. The ones not shown above are for getting the answer to 38 x 3. I toss out the decimal point, round up to 40 x 3, get that answer, then subtract 2 x 3, get that answer, to come up with 114, then toss in the decimal point, add it to the 95, and Robert is your mother's brother.

1.5 inches = 38.1 mm, to be exact.

Have to make a correction: 25.4 mm is the exact official definition of one inch, expressed in mm, not an approximation.

I saved that^. Thanks!

The guy i work for is the smartest guy i know. He knows the decimal equivilant of every fraction up to and including the 64ths in his head. Takes him like one second to tell you what say 51/64ths is. Anyway, the embarrasing thing is that he expects me and my co-worker to be able to come up with the decimal equivilants instantly and looks at me like im dumb when it takes me 5 seconds to add 1/16 and 10/16ths to figure out 11/16ths in my head. Asks me if i went to school, lol. They quit teaching kids useful stuff before i was born i think.
Oh well, its cool to work for someone like that.

I took courses in advanced linear algebra, advanced calculus and point set topology at university. My brain has been fried. I just prefer to glance at the conversion chart on the wall. You can get lots of them by going to any industrial tooling expo.

[reddragon]

I grew up with both the metric and Australian slang systems. Roughly translated, 1/64, 1/32 and 1/16 become mickey whisker, bees dick and poofteenth. I cant go much further due to censorship concerns, but it's basically a blend of algebra and abstract expressionism, as opposed to fractional mathematics. .

[Dragonhealer]

I'm. With Brave, the charts are easier, I haven't used my K log k in decades, and the great thing about the cell phone is your never without your calculator, 25,4 is my friend, and I only know decimal equivalents of fractions due to the machinist part of my background. But i'm lazy, I would rather look at the chart

Back on topic I have ordered a new set of suspension parts when I get home I'm going to make new pictures for my thread. So each part and how and where it goes together in better detail. So look for that early Feb I guess

[festyfreak39]

hey guys im starting to put together my suspension setup and wanted your opinions:

So my two options are:
Option 1:

cheap ebay coilovers, be it FSK, RSK, or rice land. Buy KYB mk1's for the back and new springs all the way around (black magic stuff)

Option 2:

these mk2 golf struts for the front, and kyb mk1's for the back and new springs.

Part of me feels more comfortable with Bilstein brand struts

I felt the same exact way as you, but I found a post from Charlie stating that the eBay front coilovers worked better than the Bilsteins he built. Whether he meant better for a particular application or better overall I don't know. I went ahead ordered the ones linked in this thread.
