My 2 cents

Perfect NA daily set up with visions of grandeur

17 x 8 +45 Enkei RPF-1. Why: light and strong rim, no issues with OEM coil overs (springs and dampers)

215/45 17 Hankook RS4. Why: excellent dry tyre, very good wear rate, very good value.

MCA street performance coils. Why: Local company, valving and spring rate designed for the platform, excellent value for the money, adjustable (20mm drop from stock height), easy maintenance (greasing).

MCA traction mod. Why: Excellent reviews from local racers.

Brake pads and fluid. I'm on OEM Brembo pads and Motul fluid. Why: Although the OEM pads are dusty the work well from cold and are easy on the discs.

Hard race Subframe and Whiteline diff mount inserts. Why: The OEM bushings are too compliant and the subframe and diff bounces around like a pogo stick.

Throw a little camber at the front (-2.5), the rear should see around -2.0 with a 20mm drop, zero your toe and then...........profit.

The cars handling will be night and day and your tyres will last for ages (zero toe).

Yes you can get bigger wheels and tyres, but, it will cost you on multiple fronts, weight, cost, performance and comfort.

Remember, your sidewall is part of your suspension, less sidewall = rougher ride, this is extremely pertinent when going higher spring rates.

Most importantly, research, alot, don't spend $1.00 until you have looked at every option and worked out any issues, modifying isn't rocket science, but it is easy to make your car handle worse than OEM.

Opinions may vary.

This car, lowered 1 to 1.5 inches, looks like it was designed for 17x8 +35 wheels with 225/45r17 tires:

You can run 17x9 +35 with 245/40r17 as well but they poke too much without adding at least negative 2 degrees camber and then you may rub on the spring perch without coilovers.
