About 550 ohms. That is if you use 3.3K resistors for the inline steering mod.

Really very little since essentially it’s the same mod, by adding two 3.3K resistors to each side of the servo wires you are putting them in series with R26 and R27 on the circuit board for a total of 4.4K ohms. The 4.7K surface mount mod has looks better and is easier on the steering servo wires with just slightly tighter steering compared to the inline mod which easier for some people to install and uses resistors that are easier to find.

This is the first thing I do to each and every Xmod I get my hands on. With this mod my Xmods have a turning radius that is indistinguishable to my Mini-Z’s, roughly an 18 inch circle.

I find replacing the resisters on the circuit board easier and faster, but I also have a lot of soldering experience and a surface mount rework soldering station. Ethier way it is a must do. Props again to gavitya if it wasn’t for this mod I’m not even sure I’d like Xmods.

P.S.
Be careful when ordering this mod off of eBay or obscure web sites, there are people selling it who apparently don’t know what a 4.7K 603 package surface mount resistor should look like, it should have a 472 on top (it stands for 47 and two zero’s). I have heard of and seen people who got everything from 470 ohm to 47 meg, it’s amazing what some people will do for a few bucks. And if you’re going to do the inline mod use 1/8 watt resistors not the honking big ¼ watt ones from radio shack, go to an electronic supply store.
