F30 alignment preparation after suspension changes

Tell the shop whether the car is a daily driver, a lowered street car or a track car. Supply the exact suspension kit and wheel/tire setup, including spacers. Ask whether the shop can measure the car at its current height and whether any adjustments need hardware the car does not have. Do this before arriving with a target copied from another chassis.

Have loose or worn suspension and steering components assessed before paying for a final alignment. Set the intended ride height using the suspension manufacturer’s instructions. An alignment made before another planned height change is a poor baseline. Record ride-height measurements consistently at all four corners so later changes can be compared.

Michelin distinguishes wheel geometry from tire/wheel mass balance. A vibration complaint may need balancing or further inspection rather than different alignment angles. Give the shop the speed and circumstances of the vibration; do not book an alignment as a guaranteed cure. Inspect tire condition and set the appropriate cold pressures before evaluation.

Request before-and-after values, the specification used and an explanation of any angle that cannot be brought into range. Discuss steering-wheel centering and intended road use. There is no universal PHTM F30 camber or toe prescription: tire choice, hardware and use matter. Keep the printout with the suspension invoice and check the subsequent wear pattern rather than judging only the first drive.
