Rear drag shocks and springs installed! (pics inside)
I figured I would share my last project. After finding broken cross shafts in my 9 bolt I traded some AC parts for a used 10 bolt. I threw a quick paint job on it and the sway bar after checking the ring gear teeth. I swapped my u joint caps and my PBR discs setup over to the 10 bolt. I didn't bother pulling my ARP studs out of the 9 bolt and putting them in the 10 bolt as I would have to mess with the C Clips and stuff.
I figured this would be a great time to install some parts I had in my parts storage area. I installed rear Eibach Drag Springs, Competition Engineering 3 way adjustable rear shocks (50/50 setting), and TDS endlinks and bushing kit.
I still need to set my pinion angle on my Spohn Torque Arm, but the hard part is basically done now I think. I may adjust the LCA bracket setting, but for now I threw it on the lowest hole like I had before.
Don't mind the paste it's antiseize. I like putting it on the rotors mounting surfaces so they don't stick to the aluminum rims or the axles as much. I find it makes it a ton easier than beating on stuff later.


Fender gap with the car off the jack stands and back on the tires.

I would like to get a replacement panhard bar eventually to finish off the rear suspension, but for now the stock one is working and the bushings are decent shape.
Front suspension plans are Lakewood 90/10s, Eibach Drag springs, Spohn K member, Spohn A arms, and Spohn strut mounts. Just need to make time to pull it apart and install them. I just have to finish wiring my garage for more outlets first.

So is the car a drag only car?

No, it's my street driven car. I've decided since I only drive 1000-2000 miles a year in it I'm not to worried over the drag only warnings on products. I may eventually even get some 15x4s for the front too. I plan on getting the car back to the dyno to get the carb tuned with the wideband. Last year was very disappointing only making 290 RWHP with the old carb due to leaks and blew intake gasket on the run too.
