Lowering Spring

It’s been a while since my last post.  I wanted to enjoy the car some before jumping into any more projects.  The back end of the car is sitting way to high so I finally bought 2″ lowering springs through Detroit Speed to drop the rear.  The first picture is the height with the stock springs.  DSE claims the new springs will lower the car 2″ from ‘factory ride height’ and that the drop will only amount to about 1″ when replacing 30+ year old springs.

The spring pack is almost right at 5/16″ thicker than the stock springs.  In the leaf spring comparison picture you can see the spring with the thinner shim is the stock spring.  I bought a universal u-bolt kit through Speedway Motors and drilled out all of the holes in the shock plate and spring perch to accept the 1/2″ diameter bolts. I machined some spacers out of aluminum to make up the difference such that the bottom shock plate will bottom out against the spring perch as it does with the factory setup.


Image 1 is before spring replacement, image 2 is just after installation, image 3 is after a 15 mile test drive.  As you can see I ended up about 1/8″ above where I started with my old springs.  Perhaps the setup will settle a bit more but probably not much.  I would recommend DSE’s 3″ drop for anyone trying to get some amount of drop.  I’ll install the lowering blocks that came with the u-bolts for an inch of drop.
