Mark Arnall admits that the F1-regulations changed to Kimi's disadvantage last season.

- The driver's weight was important in F1 because of the KERS-drvice. We did a lot of work to make Kimi smaller because he was 2-3 kg overweight after KERS was put in. Some bigger drivers had even more difficulties, Arnall told MTV3.

In rally Räikkönen is weighed together with Kaitsu.

- The minimum weight is 150 kg. We are a little above it. We are more or less where we should be, Arnall said.

- Driving rally is more easier on Kimi because he doesn't have to put up with the same G-forces as in F1. The driving position is quite different so the muscles work in a different way. We will change the training according to which parts work more than before and which less, Arnall tells.

- In rally you sit in the car more than in F1 with pace notes and transitions. The rally car bumps the driver up and down more than a F1-car. That kind of bumping strains the lower back, Arnall continues.
