About to swap rear springs, some questions.
Hey guys,
Tomorow I'm gonna be changing out my stock springs for some BMR lowering springs. I read the how to on ls1howto.com but I have a question about the last part of the write up. It says:
Since my springs were shorter, I jacked up the rear axle about 2 inches. I then placed both springs on their perches (or in my case, put the adjustible perches on the stock perch, and then placed the spring on that). Next I jacked the rear axle up again another inch or two and checked to make sure the springs were going up correctly (they just kinda flop around until load is put on them)....continue jacking/checking until there is load on the springs.
I'm confused about the part of jacking the car up another two inches. It seems that I should just place the spring on the perch on both sides and then just lower the car back onto the ground? I just dont understand why I have to jack the car up even higher? Thanks for the help! I really appreciate it!

Here's what ya need to do, jack up the cay via the differential. Put jack stands under the rear subframe or on the SFC's if you have them. Slowly lower the rear axle. You'll probably have to remove the lower shock bolts to let the rear end fall enough to get the springs out. I had to remove the LCA bolds too to get to the rear shock lower bolt. You then lower the rear another 2" after you have pushed out the lower shock mount. The springs should come out easily now. Set your new springs on the perches and raise the rear end and as soon as the springs touch the frame, adjust them into place. I make sure the coils are both set in the same (coils start and end at the same point on the perch. Lift it another inch or two and replace the shock and LCA bolts, lift, remove jack stands and your done. You may be able to remove the springs with out removing the lower shocks but it's a biotch. Loc-tite the shock and LCA bolts because the nuts on them are usually the one time tightening type.

Thanks for all the help!
I just got done with them yesterday and I only needed to replace my springs but I ended up doing alot of unncessary work. All I had to do was jack up the diff put jackstands on the frame take out the jack and then remove the springs. Instead I took off the speaker panels and removed the carpet and unscrewed the nuts (which were a PITA) before I realized that all I had to do was take out the jack and just leave it on jackstands. At least it was a good learning experience!

Hey guys,
I've been told that the car will slowly get lower within the next couple of days because the springs need to set. Well I looked at it today and it looks slammed. It seems so much lower than I anticipated. Is this becuase I am still running on the stock DeCarbons? It looks awkward and out of proportion because my front isnt lower yet. I'm just hoping that once I lower the front the rear won't look so low anymore.
