After more digging it looks like HYPERCO actually does make 4 inch, 65mm, 10kg (600 lb) springs, so i may do just that

Get a 4 inch spring and raise the perch as needed

My concern going with a 2 inch shorter spring is whether at full compression, the bottom of the cup and top of the perch will hit each other

If 4 inch is “too short” i could always stick a thrust washer or two or three and get back a little height without the perch

Everything was closed this week, so i need to wait till Monday to stop the SPL/swift order and contact the nearest hyperco dealer (performance shock at Sonoma raceway)

As for BC - someone actually pointed out that their springs are listed as “linear” but actually may not be. They have a slight conical shape, wider at the top and getting more narrow at the bottom. Wierd

Also, 326 power stocks nothing stateside, so i would need to wait for japan shipping, which is impacted. Additionally they only offer 100mm or 120mm (4 or 4.75 in)

I might as well go Hyperco which has a good rep and is stateside
