Homemade Evo Anti-roll Bar Endlinks

(c) Donour Sizemore 2008
The general outline for this project came from the BMW 3 series endlink guide by UUC Motorwerks. The parts are slightly different, but the idea is the same. Most of the parts were ordered from Mcmaster-Carr, but a few are from Pegasus Racing.

Caveat: All the parts were chosen in SAE sizing, but almost all the parts on the Evo are metric. In particular, 3/8" bolts were used where the stock endlinks use 10mm. Detail freaks may wish to substitute metric parts.
