Remark :

Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I measure the effect of preload changes?

Compare lap times and steering feel after each small adjustment, and watch for changes in mid corner grip and rebound behaviour to gauge the impact of preload settings.

Is installation straightforward for hobbyists?

Yes, fitting the nuts is straightforward for hobbyists with basic tools. Take care to seat the O-ring correctly to prevent slippage under load.

Do these affect ride height?

Adjusting the nut changes spring preload which can slightly affect static ride height and initial suspension firmness, but it does not alter the actual spring rate.
