Planning my BP-51 lift looking for advise

[Crab Sack]

After much research I have decided to go with the BP-51 lift but had some questions and looking for advise on the build.
This is the first phase of the build and so there is no extra weight front or rear at this point.
I am currently running 275/70/r18 on stock wheels with the OEM spring spacers. Eventually move to 305/65/18 once these wear out.

Here is the plan so far:
BP-51 on all 4 corners, 0 preload on the front
2721 springs on the rear, I do tow occasionally.
SPC upper control arms.
Factory wheels and 275/70/r18s

The questions I have are:

1. Should I ditch the front OEM spring spacer? I don't like a lot of rake. .5" or less
2. What size wheel spacers front and rear? 1.25 on front and 1.0 on back? I would like them to stuff and track correctly.

i'd keep the oem spacer

I’d wait on the spacers until you install the wider tires. Only then will you really know what you need/want. At that point, 0.75”-1.25” depending on wheel offset. Stock wheels are pretty sunken in at 60mm...so moving them out an inch or so certainly helps.

Preload:
Personally, if you are stock weight, I’d still put in 5mm preload unless you really prefer softest ride possible. Stock adjustments for compression and rebound are not going to correct sloppy. Just speed of rebound/compression.

**Make sure your installer understands that BP51 coil overs come already preloaded to 20mm from the factory (factory assumes you have a steel bumper/winch) so they’ll need to dial it back to zero (or 5mm) before installing.

Rake:
Don’t be afraid of some rake. It preserves available down travel into holes or off of obstacles and will leave you the balance for rearward cargo weight that will lower the back end toward the front’s level.

Any unladen truck should have some forward rake imho.
