if anyone could let me know what process they are using to install washers on car body really struggling
It’s actually delrin washers stupid auto correct
 
I know how this is going to sound, but just glue them on to the body. Rough up the side to be glued, use an old axle as a guide, and adhere with CA glue or your choice. Be sure to polish them after gluing...

I'll sand the side that will go towards the body with 320 or 400 grit sand paper.
I use a thick CA glue to around the axle hole. Put the washer on a junk axle .
Insert the axle into the axle hole. The axle will align the washer. Wait until the glue has dried before removing the axle.
Twist the axle before pulling it out. If you don't, you might pull the washer off the body.

Just a tip - leave the wood around the axle hole bare. The washer will anchor better to bare wood.

I may be other thinking it but here goes. If the rear wheels are canted so that the wheel rubs against the axel head and not the body then are washers necessary? Also, if one front wheel is higher then wouldn't only the DFW require a washer?
 
Is there any benefit to using a larger sheet of Delrin, say .25 x 1.25 inches? A washer only touches the wheel hub while a large piece would also help with the outermost inside edge of the wheel.

The wheel edges should be nowhere near the body of the car. Any contact between the wheel edges and the body will kill the speed of your car.

I was thinking about using a 1/4 forstners bit to carve out a small pocket for them to fit into. Do you think the center point on the bit will open up the axle hole too much?
 
That works really well if you want to bring your wheels in a bit. Doesn’t affect the axle hole. You’re only going in the thickness of the washer. I’d practice on a junk block first to get an idea on depth.

I know people who do this because they are too OCD to let a piece of delrin hang outside of the body. It seemed to work well for them.

Dan, Keep in mind I'm not a league racer but I've had success using a 1/4 double fluted router bit in my drill press to counter sink the washer. Like you, I was worried the forstner bit tip might cause problems.

I use a small file and make a notch for the washer to fit in. No worries about body damage that way.
