Default Round 2

IPD blue 7-9 series sport springs, stock 240 springs from a GT that turn out to be the softest 240 springs ever (swapped, probably) and some cheap coilover shocks and springs from Lawrence.

Black front 240 spring, from an unknown donor (taken from the front of a GT by VB242, hoping they were sweet springs).

Next up, IPD blue 7-9 series sport spring, front.

Starts around 130#, 145# avg, 150# peak. Some rise due to seat issues. Not a progressive spring.

Next up, 240 rear, unknown donor. Was found in a 242 GT.

poncy 95#, but 50% stiffer when in a 240 rear arm due to motion ratio.

Next, IPD blue rear for 7-9 series.

What? The same as a stock 240 spring? No, there's more. It's progressive.

The rise at the end is unresolved, so we had to test to a higher pressure. We chose a distance, and that distance wasn't enough.

95# rising to 140# and staying there.
So at normal ride height, cushy. In a turn or under load, you get less compression.

teal coilover, 350#. (not volvo related)

Shock time.
(not volvo related)
"made in canada" Pro Shocks T40902SA
(below that WB 735)

As set, good for 300#ish springs, didn't try adjusting them. Didn't see how to.
These are still available in black, starting around $80 each in a variety of dimensions.

I'll measure dimensions later. School is starting, need to sign off for a bit.
