How I did rear adjustable rear springs on a 240
Here is how I did rear adjustable rear;
Looking though different Volvo builds, I have seen how some people do it, try to get a standard 2.5" coilovers spring to work with the 5" upper spring perch. But this never seems to look right.
After doing some digging on different circle track sites I found an adapter plate that goes from the 2.5" spring perch to a 5" spring, I also found the rear VW mk4 spring perches bolts on like a Volvo. I was able to get 5" coilover springs from summit
First I removed the stock spring
Next I bolted on the VW adjustable spring perch
Next the spring adapter
Then I put in the spring, with the shock removed, there is plenty of room to toss the spring in with out compressing it.
Then I cut the bump stops
To prevent the suspension of going full droup and the shorter spring fall, and to not blow out stock shocks I had to run shorter shocks.
Most seem to go for a s10 front shock for the rears, but when I looked at the difference, between the stock and that recommended shock, the difference wasn't enough. I found that shocks from a c10 rwd fronts are shorter
Two things need to be changed on this shock, the upper mount eyelet is slight to big, KYB offers adapter sleeves for cheap
The thinnest one goes on the upper mount bolt
The lower sleeve is too short, so I swapped the lower bushing and sleeve
Those now can be installed.
Next I installed my DYI adjustable panhard bar and adjusted it to center the rear axle
Nothing but bad pics on that.
Here is a picture of the suspension with loaded
unloaded
The shocks don't let the axle go down enough to to let the the spring fall out, but I still have a good amount of suspension travel and feels nice and comfortable.
I still need to build adjustable torque rods and bring the wheels forward.
Here's before and after with both coilovers
