Street / Track Prep
I'll probably do 2-4 road course track days / year, a lot of hard "canyon" driving (hilly / curvy roads), and normal street cruising. Headed to Blue Ridge Parkway with a car group in two weeks and plan to do a track day shortly thereafter.
Based on threads I have read I'll show what I plan to do and would appreciate commentary or suggestions. Consider it a placeholder that I'll update after your comments. Engine Oil: Redline 10w50 or Castrol 10w60? Oil Filter: ? Brake Fluid: Castrol SRF (I'll also do clutch system) Engine Coolant: Summer (Pentosin blue and distilled water. What about Royal purple water wetter and what mixture?) Winter (whatever BMW recommends, I can figure that out) I plan to get a set of brake rotors and pads just for the track Pads: track (PFC 08) and street ceramics (PFC 2, or Akebono, or Euro Rotors: ? |

I'm going to run the car like this (stock form) until I am pretty familiar with it then next year a few mods:
Front Sway bar: what thrickness, brand, etc Camber Shim Kit or Camber Plate? -2 or -2.5 degrees? Would I go with more camber while on stock wheels/tires then could I give up some camber to save tire wear when I get wider front wheels? I'll run it like that in 2018 then get a summer set of wheels/tires before 2019. I'll keep my stock wheels with a set of street tires: Wheels: still looking, suggested setup to reduce understeer and reduce rotational and un-sprung weight? APEX ARC-8 with 245 front and 265 rear? I do not plan on changing the suspension, rolling fenders, etc. Tires: Summer street and track; not track only. Looking for good heat management, consistency during 20-30 min track sessions, and decent tread wear within this group so the cost isn't too crazy. |

Sounds like you should leave as is for now. General maintenance items. Fresh brakes.
Sticky summer street tires. Maybe get a set of sport springs to compliment the slight increase in front negative camber. Definitely replace your front control arm bushings with medium poly and replace the rear trailing arm bushings with a spherical bearing kit (Synchro Design Works). |

Thanks for the tire suggestions. I'll take my time researching tires, wheels, and suspension but I have some time. The car has at least different springs (maybe more), has been lowered and has magnaflow tips (hopefully full catback). I can't see under the car because it is so low but once I have it on jack stands to check the brake pads I can find out what is on it.
Any suggestions on the engine oil, filter, brake fluid, and summer/track coolant? I've seen conflicting suggestions across threads. |

Spherical bearings seem overkill for a car that sees such light track duty. Even on my car I don't run spherical, OEM plus limiters is fine.

I have 4 track days on a set of RS4s and absolutely love them. They seem to be wearing well too.

I ran half a day in the rain at Watkins Glen and they were fine.
Rain was heavy at times with water running cross track in some sections. Rain is rain... But they really did as well as could be expected

Don't run a staggered setup if you want to track it. I fit 18x9.5" APEX ARC8 with 275/35/18 Michelin PSS. These are the perfect tires for 90% street and 10% track. Very quiet, very smooth, work in the widest range of ambient temperatures. Good tread life. Of course tracking on stock suspension will be a little wonky, but see how it goes. At least a good alignment and square setup will be a huge step up from stock. Oh yeah, and some good track pads. Rotors take your pick. |
