What you don't need:
  • Front UCA
    Mcpherson Strut system can be camber adjusted with a lot of flexibility with just front camber plates (in contrast to many double wishbones). If your coilover system has front camber plates, that's all you really need. If your coilovers don't have front camber plates, consider purchasing them.
  • Rear toe links
    For rear camber adjustment, you want rear lower control arms. You only really need toe links if your car is significantly lowered AND you want close to zero rear camber AND simultaneously low toe. For track alignments (-2 deg or more) and close to zero camber, you don't need the toe arms.
What you might want/need
  • Dedicated air-oil cooler
    The water-oil cooler from the factory is likely insufficient if you are an experienced track driver, especially in warmer climates. Gen1 cars often saw insufficient oil pressure at higher oil temperatures. Some may argue that you can get away with it as is, that oil coolers add their on risks, or simply to use heavier motor oil. But if this is your track duty car, I think oil cooler and 0W20 is the way to go.
  • DOT4 or better brake fluid
    Not much to say here
  • Front suspension camber plates
    See previous section
  • Rear lower control arms
    See previous section
  • Add Trans & Diff Oil Maintenance Interval
Things to reconsider
  • Coilover Spring Stiffness
    I'm not familiar with MCS systems, but the spring rates you provided seem a little soft to run with a dedicated slick tire on the platform
  • Mismatched brake compound
    It looks like you have chosen a different front vs rear braking compound. I'm not familiar with Ferodo line-up, but mismatched compounds can affect your brake bias and how the car is balanced during trail braking if their friction/character are significantly different from each other. If they are matched for each other, it shouldn't be a problem
  • Sway bars
    I would say stay away from sway bars until you run out of adjustment in your coilover system. There is no swaybar panacea or universal preference on the platform. I like Eibach for sway bars, but there are many out there that do the same thing and are built well.
