I have king springs front and rear in my 164.

I haven't.

I have had orange K-Mac 1 inch lowered springs in my original 144 but that was 40 years ago now. Not a bad handling / ride compromise.

They got changed to custom-made blue springs from Lovells, which were 1.5 inch lower than standard and 20% stiffer than their usual sports rated sets. That worked great on the track, not so great on the pot-holed streets.

AFAIK, Kings haven't made off-the-shelf 140 spring sets for a long time.

King’s may not have made 140-specific spring sets, but is there anything similar which a decent suspension joint could recommend?

My 242 is sitting on King’s springs which were actually for a Commodore. Suspension place took corner weights & height measurements for standard, asked what I was after, took the Bilsteins I was using into account, did some calcs and the end-result was the same as some slightly-lowered King’s Commodore springs. King’s would’ve done a custom set at the time, but this was about 1/3 the price!

^ Funny, I wondered if pre-VR Commodore spring rates would work on a 240.....

140 standard rates are about 305 lb front with 126mm OD, and 195.7 mm length at load.

Heavy duty standard rears? 115 lb, 127.6mm OD, 283mm length at load.

Torana front springs fit in the front of a 164/140.

240 rear springs fit in a 164/140, subject to the usual stuff about pigtail ends on one/both ends.

Thanks for the advice and at this stage it may be to much me to do. Esspecialy after doing gearbox changeout with the car going well again. The original box is available for pickup in Gympie Qld only reverse was without a tooth, but who wants to go backwards. Thanks for the measurements Major I will keep them for future use.

Nico142 500lb in the front and about 130lb in the rear, and dropping the ride height an inch, plus adding a rear sway and going to a larger front sway bar, makes for an excellent road-going package which will handle and be comfortable. The factory rates are very soft and the front bar is very small.
