I have an X1 2015 that I've recently begun racing after campaigning Tamiya cars. I'm wondering if I missed installing a part during construction. I seem to have more droop in the rear pod than I should. With the front, middle, and rear ride heights at 5mm, I can raise the chassis at the main chassis/rear pod junction to nearly 8mm ride height. While this is great for putting power down, it's not to great on the on-power steering. Did I miss a shim that should be inside the shock? I've put more preload on the spring collar for the rear shock and this has improved the balance, but I'm not sure that this is the correct answer.
