Rear suspension too stiff

Thanks for all the responses.

I'm sure the nuts are WAY over-torqued so I will try that first. I've been leaning towards the KYB shock option also as the QA1's are overkill for me. Fronts are Monroes so probably replacing all 4 as have no idea how old the fronts are.

Will post when shock swap is done if anyone interested in the QA1's. Single adjustable if you are wondering.

If all fails, I'll turn my mirror around, drive real fast until I reach the time when the previous owner did all of this suspension change and slap him silly. Ha!
