New springs, rims and tires

[tcpty]

With the 17" tire your speedo will read 1.5% slower than the stock diameter tire (205/45/17), so you are going the wrong way here, even if by just a little, but you will have a cushier ride

With the 16" combo your speedo will read 4.1% too fast. The TS has a very short geared tranny and the 16" combo will make you feel that you have shorter gearing at the loss of top speed. So this combo will give you a faster way through the torque curve, improving your "drag starts"

If you want the look of a 17" and a lower gearing feel than stock like your 16"s, try 225/35/17. I have Yokohama A510's and they are awesome in handling, wet or dry! And they look good to boot once you lower your car with the new springs! I have a go-kart with this combo. Have a look...
