You're on a dangerous road here. Same thing I did when I started. You wont learn what you need to with this setup and it will set you back as a driver.
Right now, your suspension cannot handle those tires (in front). Use some all seasons or summers. Expect your times to be high, the 1 is not the fastest autox car. Also; do not mod your power at all, stick with suspension upgrades. It's the achilles heel of our cars when you run on non-run-flats.
Things to do that will help in order of importance and cost benefit.
- Raise your limits (Performance brake fluid and pads, high octane gas if available)
- Front Camber (m3 bits + camber plates. You can use Dinan ones easily)
- Limit your roll (m3 front/rear sways - stick with coupe sizes, springs)
- Connect the car (m3 subframe bushings + other bits)
- Get some Grip (Wider wheels/tires, LSD)
My best setup:
- M3 sways, subframe bushings, control arms
- Dinan Springs/Dinan Koni Shocks
- Vorshlag Camber plates (at -3.25 deg)
- Apex 8 Wheels, PSS tires (255/275) <-- should be 245/275 for no issues
- Cool Carbon Brake pads with Super Blue brake fluid
- Quaife LSD w/3.46 gearing
My advice:
- Burn through your run-flats and stay stock until you can correct for your car when it gets twitchy and you start losing control. When you're at the point of being safe, change 1 item at a time (for fun) and see what it gets you. Know that this is an expensive hobby and certain mods can actually make things much much worse. Talk to other people at autox and see what they do. Generally people gravitate toward an ideal setup.
