I do engage the M button and shut all the DSC controls. The Hoosiers help a lot, especially of the PSS (I haven't done any done any comparisons).

If you want to start a thread, please feel free. Eveyone will have an opinion. You can include my comments (what little of them there are).

I haven't been to the track, only autocross.

Car is stock and I am using street tires, RE-11's in stock size which were a huge improvement over the PS2's. I target HOT pressures of about 29PSI in the front and 27-28 in the rear.

DSC completely OFF (MDM costs 2 seconds on a 45 second course), M sport mode ON, 1/4 tank of gas at start of day. That's it.

Unfortunately, I installed a Mad Dad midpipe before my last event which moved me from BS to ASP!! SUCKS! I am not a professional autocrosser, just do it for fun, but it still sucks to get PAX'd into the depths of hell!

From about 2x half-seasons of Autocross and Track, here are is what I've gathered with the car:

Stock vs. Autocross Setup Recommendations
Stock vs. Track Setup Recommendations
- Vorshlag Camber Plates & Wider Tires (from stock)
- No more Oversteer concerns when putting power to the rear
- No more Understeer concerns when diving into corners with speed

MDM vs DSC Off
- DSC Completely OFF on Autocross
- MDM for Track until Competitive Experienced Level (Not worth Losing Car)

M-Mode vs Regular Throttle
- Regular Throttle for tight Autocross courses
- M-Mode ON for Track or High-Speed Autocross Courses

Tips for Driving on Stock
- Enjoy the car for what it is, then upgrade and get Camber Plates to feel a world of a difference

Launching
- 2500-3000 rpm steady launch with stable grip on concrete will provide greater speeds once kicked into 2nd rather than slip-n-sliding in first with a higher rpm launch.

Misc Tips:
- Target Michelin Pilot Super Sport Tire Pressures: 36-37 front, 32-33 rear HOT
- Autocross/Track Camber: -2.8 degrees (Max Setting on OEM Springs)
- Driving Camber: -1.5 to -1.8 degrees
- Obviously, all cooling/heat systems set to OFF
- Most importantly, Have Fun!


I'll keep updating this post as I gain some more experience.
