Yup that is us
The only true 235 is i think Corally right out of the box.
There are some companies who make parts to widen cars from 200 to 235 and there are people who design there own parts like Joost K at the Dutch forum.
He is running a 235MM car based on a RC10R5 i believe without extra hubs to make the car wider.
He designed his own chassis and parts to widen the front and i think he is using IRS parts at the rear.
This car is one pretty sight to see and from what i heard a dream to drive.
Or he is just that good
I have a Academy SP3-X almost PRO that is from the box also 235MM but is is discontinued.
Sometimes you see a kit on e-bay but that is rare.
I know one to find that is only 80 euro's but that is the stock version and not the pro with the carbon and alloy parts.
If your craftfull you can turn it in a Pro version that drives very well.
Here is a pic of Joost car and the Academy Pro
