I fitted two Falken FK452's to the rear of my ED30 last weekend, they are just coming up to being worn-in. Ordered them from Camskill and they came next day.
The FK452's come highly rated as a performance, value for money tyre by literally loads of other car forums.
In my oppinion, pay as little as you can for your chosen tyres. That allows you to spend a little more on making sure you wheels arent damaged when fitted. I'm always careful of "fully fitted" prices as sometimes its just because the place couldnt give a monkeys and turns jobs round in 10 mins.
I paid £30 to get my two tyres fitted, they took over an hour to do the job and kept the wheels spotless.
This is especially important with the GTi wheels. Being 225/40/18, they are pretty low-profile.
