Just did 900+ miles to Windermere weekend.
Greased before leaving.
Just come in after regressing.
Lower nipples just needed 3 trigger squeezes on pneumatic gun, gave uppers 5.
I've done 13k since getting Scarlet just under 2 years ago and kingpins still looking good with no signs of shimmy/ vibes. Mileage now 39k .... I will have to double check the service history as no mention of kingpin replacement BUT springs are Mulfab replacements by previous owner so possibly replaced same time but I don't recall invoices etc for the parts/ work.
When replacements are needed then it's hard chrome and earring upgrade.
Suplex??
Undecided as not tested a car yet with it fitted.
