886x Spacer

I installed a set of 886x springs two weeks ago and achieved 3" of lift on both sides. After a week, the driver's side has sagged 1/4", yielding a 2.75" lift. I put in a 5mm trim packer to make up the difference, which brought it back to 3" of lift on both sides.

After another week, the driver's side has sagged another 1/4" and is yeilding a 2.75" lift again. I would like both sides at 3" of lift. What is the best way to achieve this? I was considering a 10mm top plate spacer for the driver's side, but according to wheelers, it will raise it 1/2" - 5/8". If I get 1/2", that would be great, but I don't want 5/8".

 

I have the 886's with the largest top plate spacer wheelers offers. I don't think it would hurt I put the 10 mm spacer in there.

 

I think an 1/8 of an inch would be within my tolerance level. Personal preference I guess.
