This thread is a "How To" for slamming your 4G chassis. I have some taller diameter wheels ordered and will share that info when they arrive.
The wheels used here are Wizzard .250" double flange narrow rims. Tires used are Wizzard PVT05, they have an outer diameter of .500" on a .250" OD rims.
Part #'s below are from Lucky Bob's site.

First step is to cut down the wheel axle flange. Only take about half off. I used a dremel with a cutting disc to remove some material.
After you cut down your axle flange, mount the rims and tires to your chassis. As you can see I could still go a little narrower by trimming more off of the rim to axle flange. You don't want the tires to rub against the rail.
These tires are made out of a very soft compound and depress when set on the track which can cause the chassis to rub on the track. To avoid this you'll need to remove your traction magnets for the next modification step.
After removing the traction magnets, drill out the magnet mounts.This will allow the magnets to sit higher than stock position. I used this dremel tool to open up the mounts. You don't want to go to big otherwise your magnets will fall out. I open them up enough so that the magnet will still be held in place. No worries if you do open them up too much, adding a drop of super glue or epoxy will hold them nicely in place.
I always start by only installing one magnet. Most likely you'll only need one traction magnet if your using a stock armature or even a mean green armature as long as the track volts do not exceed 20. Do some testing with just one magnet, then try two to see what works best for your situation.
This pictures shows the air gap between the chassis and track after the above modifications.

It's just my opinion that slot drag cars such as Pro Stock and Pro Mods look better slammed. I know I skipped a few things in this post and will update it tomorrow. If you have any questions, feel free to ask.
