Speedometer will not read correct. And what about the gearbox? Gear ratio?

You have to change the calipers and discs to 7,5. There is a kit available from Mini Spares.

Brakes are under control guyS :D

I am going for 7.9" discs and calipers, A bit less hassle to fit than the 7.5" cooper s set up. As they use the same flanges as the 8.4" set up.

My final drive is 3.21:1 (which is the same as metro turbo and japanese SPI), not sure why my car has this, but according to the engine code (12A2Ek71) it does. I can see that the duration of acceleration is longer with 10's compared to 13's but teh top speed in each gear is lower.

So will changing to 10" wheels be a problem at the besiktning?

Well, should not really. As I understand the only thing they should bother about is the circumference does not deviate more than +/- 5% from the diameter the car is typed for.

Thanks Janne!

There is a 3.96% decrease in size between 175/50/13 and 165/70/10.

That was very interesting. And it'll fit with 10" Cooper wheels?

Most 10 inch wheels fit, the ones which don't tend to be "older" styles. Minisport also do a vented 7.9" disc.
