Do these in order before the first reading. Most bad corner-balance results come from the setup, not the adjusting.
Turning a spring seat
- Driver out. Lift the corner until the spring is unloaded, and put a stand under the car before you reach in. Take the wheel off if you need room.
- Loosen the lock ring with a C-spanner and turn the spring seat. Turning it up raises that corner and puts weight on that corner's diagonal.
- Measure how far the seat moved with a ruler or calliper, or count turns if you've entered the thread pitch in Setup.
- Tighten the lock ring, refit the wheel, lower the car, driver back in, settle, read.
Never work under a car held only by a jack, and never turn a spring seat while it carries weight.
Setup & targets
Target
Equal diagonals makes LF + RR equal RF + LR. It's the usual target for a car that turns both ways. Proportional splits each axle left/right in the same ratio as the whole car, so the front's left share equals the rear's. With a driver in a left-hand-drive car the two targets usually differ by a few tenths of a percent.
Ride heights
Enter ride heights on the pads and the app picks the adjustment that keeps them closest to these targets. With no targets it keeps left and right level.

Scale readings with the driver inAdjustment you're making
Spring-seat moves, in mmTap Use this plan above to fill these in, or enter what you actually turned. Save the round, make the change, settle the car, then enter the new readings.
This session's rounds for the selected car, what you changed after each one, and what that change did. The app uses these results, plus this car's past sessions, to learn how much weight one millimetre of spring seat moves.
Once the cross weight is inside your tolerance, finish in this order.
