Firstly this is a completely unbias opinion and it is just for anyone interested. I loved my Type R and after a small time of ownership I also love my ST.
They are both quite similar in that they are obviously hot hatches, the Type R gives it's power very high up in the rev range whereas the ST puts the power in straight away with a growl rather than a scream. The overall 0-60 times are supposed to be the same but I seriously think the ST is quicker, and definitely pulls way past 60 quicker than the R. The gear changes were more snappy and rifle like in the R. The ST has quite short throws also though.
Overall I think the R actually sticks to the road a lot better, the ST scrabbles for grip occasionally (not the tyres Eagle F1s) and can't put its power down straight away without wheel spin. Don't get me wrong though, show it some corners and it definitely goes around them, theres not a trace of understeer that I can find just yet. The feel from the steering is about the same in both cars, you feel secure that wherever you point the wheel the car will go.
The ST wins this hands down I'm afraid, they have somehow managed to combine a lovely ride with fantastic handling. The R was fantastic at handling but it's bouncy ride (even on eibachs) just put me off the car and I actually found that on some roads I would have to go slower just due to the ride.
This is one that the ST wins hands down. Obviously mostly due to being a much newer car, theres absolutely no rattles (that I've found yet) and the materials makes it a lovely place to be. Yes i do miss the querky interior of the R and the futuristic look. Whilst we are on about the interior the Recaro seats are fantastic, BUT I did find the R's seats much more comfortable to sit in, the ST's kind of pinch at the sides. There is about the same amount of room inside the cars but the boot space is slightly smaller on the ST.
Beauty is in the eye of the beholder. But lets all be honest, a Standard type R is starting to get on a bit... its still a beautiful car but i personally think the ST has it in the looks department. Its not as chavvy as the old one and seems to have grown up a bit.
This is the tricky bit. In a sentance, currently, at this moment in time. The ST wins. As an all round car, comfort and power, economy and day to day duties of the car it's just better. Obviously a lot of this is due to just being a newer model.
IF I wanted a more performance only orientated car, maybe just as a weekend toy I think I would be tempted to get another R and mod it out completely.
Well there you go guys. Please feel free to ask more questions if you feel I've missed bits (which I probably have) They are of course my own views though
