I'm finally at the fix the severely sagging rear springs project for my car, and am wondering if there's any guidance on where to set the lower spring perch for the new rear Bilstein shocks?
I'm keeping the car as sock as possible, think of me as a James May if you must, so I have a new set of stock ride height springs (85 lb) and the new replacement struts. Comparing the old and the new side by side, it almost seems that I need to move t he circlip all the way to the top on the new shocks... but that seems almost crazy! Since I'm aware that the new springs, at 85 lbs, are heavier than the originals (maybe 70?), would it be better to move the perch down one relative to the old shocks? Old springs/shock on the left, new on the right (IMG:http://www.914world.com/bbs2/uploads_offsite/1.bp.blogspot.com-18091-1555182313.1.jpg) Any advice or recommendations out there? The stock rear sway bars stay (front and rear), which was also a driving motivation for keeping a lighter weight spring in the back. Maybe it's time for a project thread... but progress is piecemeal and slow, so it might drag on, and on, and on... Thanks! Robert |

Based on this, I'll probably have to adjust mine down. Don't want to hijack, but if you have a pic of the dots on your springs Rory, I'd love to see it. @rgalla9146 |

Today I removed my front spoiler to do a minor touch up. I put the spoiler on a work table outside. A breeze turned my minor touch up into a fiberglass festival. ....and repaint. Pictures of rear spring paint dabs to follow. |
