Carrera Modern GT Tuning Series

Basic Wood Track Tuning

Tuning is half the fun of this hobby for me. Carrera makes some very nice and affordable models that can be excellent performers with just a little effort. The recent Ford GT is a prime example and it motivated me to share my approach.

Not only the Ford GT either. My favorite is the The Chevrolet Corvette C7R and we cannot forget the Audi R8 LMS. All three of these cars have unique identity, but have enough in common to have some really close competition.

The articles are in a series that is easy for you to choose from.


My goal is to tune them for my wood track (non-magnet) while keeping a budget in mind.

This means I will stay with stock running gear. I have the tools to tune the stock wheels and unless damaged, they work well enough for my racing.

  1. Stock Running Gear – Wheels/Axles/Motor
  2. Original Chassis
  3. Combination of Urethane & Silicone Rear Tires

Special Tools

I will use a tire machine.

If you don’t have one yet and you want to get the most out of your models then it’s time to start shopping. They can be a significant investment at first, but I assure you that they pay for themselves in a very short time.

Tire Razor Machine

Soldering Iron

Set Up Block (Optional)


Specific Parts List:

CG Slot Cars Carrera Guide Adapters: Standard 

Sloting Plus Universal Guides

Paul Gage Tires #PGT 20125 LMXD

*Silicone Option – Quick Slicks CA02/CA03 (I used CA03F FIRM)


Bench Stock Parts – *These are parts I have on hand for general tuning.

Tinned Copper Braid

Silicone Coated Wire

Guide Shims

Brass Ferrules (wire eyelets)

Hansens Hard As Nails

Super Glue


First a quick look at the CG Slotcars adapters.

This is the only major modification performed and it is a very important one.

Without being able to adjust the guide height, the performance of the models will simply not be ideal for my track surface. In stock form the front wheels support too much weight and in cases such as the latest Ford GT, the guide is not nearly low enough into the slot.

Using these adapters accomplish two things:

  1. Allows proper depth of guide blade to be set.
  2. Allows front ride height to be easily adjusted.

In the video you will see how to check what adapter you need for a particular car.

There are two sizes as shown, but you can use either if you don’t mind a little sanding work.

The STANDARD size is the size you want to use for these models.
