If you’re a first generation Stalker owner (Classic chassis) with an upgraded Coleman Racing steering rack (although, I’m probably in a very exclusive group, even for Stalker owners), you may need to address bump steer. After the rebuild of my car, and following tracking the car at VIR, Barber and NJMP in 2018, I felt the steering needed further tweaking. In short, the car drove like a three-legged pig (my emphasized opinion). It didn’t dart around, or present any bad habits that felt completely unsafe, but, simply put, the car felt mildly unpredictable in a turn. Also, when driving around locally, certain road surface imperfections would try and convince the car to momentarily, and ever so slightly, choose another path.
My resolve was to add two .75”x1” hardened steel spacers from McMaster-Carr; yes, this absolutely should have been addressed during the build, but.... Adding the spacers aligned the tie rods parallel to the a-arms in horizontal plane. Adding the spacers also required my using longer 1/2“ (AN8) bolts (aircraft grade) from Aircraft Spruce to provide the specific grip length.
The before/after drive told the tell. The car, when driven locally over the same driving surfaces that produced bump street prior to adding the spacers, exhibited zero bump steer with the spacers installed. However, as they say (whoever ‘they’ are), the proof is in the pudding. A track day will better reveal if the car’s track etiquette has truly improved. Hopefully, a trip to Barber in the near future will have me revisiting this post with positive feedback. To be continued....:lurk:
