b'Tech Services Ron Sutton tech SeRviceS foR PRoduction caRSNo production car from the 50s to the early 90s comes from the factory with the suspension mounts exactly mirrored from side to side. None. Nadda. Ever. The factory production tolerances are 1/4 on every point & they add up. We typically find the cars do not handle the same left & right because of this. The exceptions are C5, C6 & C7 Corvettes.If you purchased a Race Car in a Box package from the RSRT Muscle Car Catalog, they come withTECH-40 in the package, at no additional cost. You just need to do the work, measure the suspension points on your actual car & correct the LCA Pivots. If youre NOT buying a Race Car in a Box package from the RSRT Muscle Car Catalogand youre building yours differentlyyou will need to purchase TECH-40. If youre doing this a piece at a time, which is fine with me, TECH-40 & a $50 LCA True Kit will be the first things you need to purchase from me.Measuring your cars suspension & steering typically takes two rookies with common measuring tools about one dayas long as were using a spindle I am familiar with. It will take you longer if it is a spindle I dont have dimensions on. The top photo shows the basic tools you need to measure your suspension. The next photos show Lance Hamilton utilizing the LCA True Rod Kit to do the LCA modifications matching up the left & right LCA pivot axis on his AutoX winning Monte Carlo.After providing me with the completed measurement form of your cars dimensions, I calculate your actual cars geometry. There is a schedule for this & typically the wait for me to get to your project is around 2-4 weeks. I outline the minor changestypically less than 1/4to match up the left & right sides. When modifying the lower control arm bucket holes, I will guide you on how to match them upand how to get some improvement as well. Once your mods are madeand I know your cars actual geometry & corner weightsI can work out an awesome out-of-the-box spring & sway bar rate setup for you that will provide high grip & neutral, balanced handling. This takes me about 2 weeks on average. Sometimes longer. Remember, no magic wand. 15'
