Useless Facts and Tid-bits

preliminary!!
To start off;
If you are reading this page, you must have absolutely nothing to better to do.
The reason for this page is so that I can write down little Honda "facts" that come to mind that may be of interest to somebody. It's all a bunch of useless crap that I don't want to waste brain space on.
1. The rear trailing arm on an EF Honda with drum brakes weighs 32.5 pounds. That's with all the drum stuff attached, but not with the control arms. The rear trailing arm for an Integra with disk brakes weighs 39.5 pounds. The Integra set-up is the similar to what is on the 90/91 CRX Si's. That means that the disk brake set-up weighs 7 pounds more than the drum set-up. (be careful with swapping arms due to the parking brake cable having a couple different lengths)
2. You can buy rear trailing arm bushings from Honda and they seem to be exactly the same as the ones Mugen sells. It's part number 52385-SR3-000. The outside diameter of the bushing is 3.170 inches. Your local dealer will not be able to find this number by looking through parts listings for the car. You have to provide him with the number and it may only be valid at a Honda dealer (not Integra).
3. You can also buy rear trailing arm bushings for the Integra arms. It's part number 52385-SK7-N02. The outside diameter of the bushing is 3.352 inches. Your local dealer will not be able to find this number by looking through parts listings for the car. You have to provide him with the number and it may only be valid at a Integra dealer (not Honda).
4. The Integra disk brake trailing arm assembly uses a larger wheel bearing than the Honda disk brake trailing arm. Bigger is better but I'd bet the reason is mostly due to the fact that the Integra weighs more.
5. You can ID EX knuckles (also known as spindles) by the fact that the left (drivers side) one has the number "LH3-A" cast into it (on the arm that goes upward to the upper ball joint. The right knuckle has the number "RH3-A" cast into it.
6. The 90/91 four door "EX" civics have the larger diameter front brake rotors (10.3"?) and still have the same geometry as a standard fourth generation civic. They are hard to find in junk yards!
