Steering vibration under medium braking ?
 

caused by what ? Warped discs perhaps ?

thanks in advance,

Usually the case!

as said this usually the case...

your not wrong

or pad deposit on the discs. what pads are you running? It might be worth doing some normal driving for a few 100 miles to see if you get any improvement.

Agree with the above BUT when was the last time you had your wheels balanced? If it's a long time it may be worth getting them done, and it may just cure your problem! - It did on my 03 STi

wheels just balanced a few weeks ago, when i put on some winter treads.
pads are pagid fast road on original JDM STi discs, which have seen 25000 miles. (car is an my03 jdm STi)

any ideas ? :confused:

If the problem didn't start when you changed the tyres I would say check the disc's..
