I'm pissed. I got taken for a ride by a flat brimmed evo doucher. He said his suspension was all good, not blown, used only with stock springs. Ok, I'll give him the stock springs bit because they definitely had been on the struts for a long time (they were really dirty), but if you think 'not blown' means every mediocre bump in the road causes a loud *thud* on rebound, then you've smoked too much.
One of the struts is ok, but the other is a pile of S. Also, it may settle a bit more, but even with a little less than 1 1/4 coil cut, the front still sits a bit higher than the rear.
I know every car is different, but I thought all of you on stock cut evo springs were getting too low with 1 coil and would have preferred less. Maybe the camber plates I'm using sit a bit taller, but I just compared them with the evos and the difference is negligible - less than 1/4 inch taller at most.
WTF?
So, for suspension round 3, I'm thinking about getting koni inserts and moving the spring perch down so I get the ride height I want, but still maintain full shock travel. I did a quick shock travel check by putting a zip tie around the strut shaft and after driving through a fairly bumpy part of the neighborhood, I'd probly be hitting the bump stops. This also leads me to believe that even the strut that doesn't sound bad is on its way out because it was traveling pretty far.
Any suggestions would be appreciated.
As for some pictures of what I am working with, here's why I don't just use the evo 8/9 springs and top perch with the evo X struts I have...
As you can see, they are nearly identical (X on the left 8/9 on the right), except for the X strut being an inch or so taller.
As for other differences, the lower perches are pretty much the same. The X has a hump on the inside to locate the spring and the 8/9 has a lip on the outside.
As I had mentioned above, the shoulder just below the top threads is 2mm bigger on the X than the 8/9. (X is below 8/9: 17mm and 15mm respectively)
So, I made some new bushings for the bottom with a smaller ID. I could reuse the top ones because its the same 12mmx1.25 thread.
This isn't the best shot, but here's all the different pieces that go on top. Once again the X spring perch is on the left.
Here's some better pics of the spring perches. X first
And 8/9
And finally, the reason why the lower bushing needs a shoulder on it is so the spherical bearing has room to pivot for camber changes.
