Just bought a Vitz RS, I have some questions...

[JudgeM]

Greetings to all ( I think i posted this in the wrong section so I repost here)

I recently purchased a 2005 Vitz RS (JDM spec) 1.5 5 speed manual.
So far has been a great car and I love it, I just had a few queries maybe some of you could help me with:

-The suspension setup feels quite stiff, is that normal for the RS ? I looked at the springs and they look stock.

-I have driven a few manual cars, and the clutch on mine seems quite stiff compared to the rest. Its a small car but the clutch feels quite heavy, I drove a Honda Fit and a Corolla hatch and they both had very light clutches. Even a Hilux has a lighter clutch than mine.

-Now this problem I also have with my Vios. The accelerator pedals are those e-throttles. I find them waaaay too light and sensitive. On my Vios if I rest my foot on it, it will rev to 5K rpm. The Vitz is bit better but still not great. Is there anyway I can stiffen them up ?

-My side mirrors have led turn signals on them, but the right side one is totally dead. I am generally good with taking parts of cars apart and repairing them etc, but how would I go about opening up the mirror, I don't see any easy way.

-I've got smart key system but only one key. How do I make a copy. From what I've been told, If i lose this key, i am screwed.

Regards.
