Transform racing body into stock car body
Posted by Fredd on Monday, July 31, 2017 12:18 AM

I have been searching the Internet in need of some advice for converting racing model kits into a stock version of the car, since many cars come only in a racing (DTM/ BTCC/ Rally) version, with its bodykit already "installed". In this case I have bought the 1/24 Tamiya Alfa Romeo 155 V6 Ti "Jagermeister", which has racing (wider) fenders and side skirts I need to get rid of. The interior comes with rollbar, a simple dashboard and the two bucket seats; I guess there will be quite a lot of work to do there, but not as much as the exterior. The idea is to make a slightly tuned berlina, like a car you would see in the street. (I would really like to have a factory stock version, but it will be impossible to make because there are no kits with, say, the original dashboard, door panels, front and rear seats, etc.)
As I said, I want to narrow the body's with, but do not know really how to in order to avoid ruining the model by melting other parts of the plastic body. I think I may have to cut them with a dremel or something similar, and fill the rest with styrene and putty, but I am not quite sure how to do so.
If anybody has done something similar or has any ideas that can be useful, great.
Thank you.


I will leave some pictures of a finished model and of the factory-stock car

Hi Fredd,

  Unfortunately, your photos are not showing up. What you are talking about is called "channeling". Channeling is a technique used on full size and model cars to reduce the width of the vehicle. It is VERY difficult to pull off without changing the look of the vehicle. Usually channeling will remove certain centered details like the chrome trim in the middle of a hood. To make the car stock, this would need to be replaced after the channel is done. 

Things like fender flares and such can be ground down with a Dremel, but I urge you to work slowly and only remove what needs to go. Any underlying plastic should be left to build on top of or to sand into shape.

If I remember correctly, both Scale Auto and Model Car Magazine have done articles on chopping and channeling. You might find them if you google it but, no guarantees.

My favorite color is clear. I am also ambidexterous, I can screw up equally well with either hand. I am 53 years old and been building for most of that time. :)

So what you want to do is take a factory stock car, that was chopped up and turned into a race car, and chop it up again to turn it back to it's stock condition ?

This may not work out  the way you want it to. Might I suggest you look for a resin body to start with. You will still have some work to do but your "frustration" level wont  make you want to run into oncoming traffic.

Dont worry about the thumb print.... paint it rust and call it battle damage

Yes, I would basically like to remove the fender flares, which are pretty wide and then make some work on the front bumper (probably won't take a lot of effort as the rest). The thing is that I will have to fill the space left with something else, since by removing the fender flare the car will have a big mudguard for big wheels. Tongue Tied

Let's see if these images can be visible; in the last one you can appreciate the fender flares more clearly.

The idea is to chop up the "extra" body parts such as fender flares and maybe sideskirts from the DTM (racecar) and try to make it look as a factory stock car -or a tuner.

As you say, it will take a lot of working time, and of course, patience.
