Hi guys,
I have S13 coilovers in my 910 bluebird and they suffer from hitting the yoke of the diff into the floor pan on hard acceleration if lowered too much. Anyway, when i put the coilovers in, it only ever hit when i had people in the back seat. Lately however, im finding that its hitting a lot more often even with just me in the car. I have added preload to the springs but still hasnt fixed it.
Do coilovers eventually need gassing or servicing? They are HKS hypermax units.
Thanks
