Bilstein 5100 and spacers on 05 Prerunner

Trying to level out my 05 prerunner access cab 4 banger. im 3 inches higher in the back. First Idea was 17 TRD OR struts with 2 inch spacer. It works but coils way to stiff, I think because coils were designed for 6 cyl. Round 2 Bought 5100s and instead using the 2.5 inch setting with stock coils (to stiff) thought I would use a 2 inch spacer lift and leave shock at 0 to 1 inch. Not sure if the geometry would be the same.so I would get the same stiff ride. Any one try this

 

Don't use a spacer with 5100's, you'll defeat the purpose of them. They are designed to pre load the factory springs, or use eibach, OME, or ToyTec springs with the 5100's. If you're going to use a spacer, just keep your factory shocks.

 

So should I buy new factory shocks or maybe use the 4600s I thought i would use the 5100s and leave them at or close to the original setting or maybe 1 notch up. for the price I figure they would be a better choice than stock

 

5100's only advantage over the 4600 Bilstein shocks is their adjustability and ability to handle the heavier spring load. You can find lightly used 4600 shocks for super cheap.
