I’m eyeing 2021 to finally start tracking my '08 E90 6MT. Got some questions about preparing the car (bolded points below), and would welcome other feedback. I've only been on track a few times, only one of which was a real open track day, and never with this car.
This is not a track build. The car is already way faster than I am, so I'm not looking to make it faster. All I want to do is make sure it doesn't do anything stupid.
Only real mods so far are Öhlins R&T, FTAB monoballs, and camber/caster plates (did those for daily driving fun, not for the track). Tires are Michelin Pilot Sport 4S, 245 front / 265 rear. No R-comps until I’m less of a noob. No powertrain mods of any kind, now or in the foreseeable future. Rod bearings, cooling system, and valve cover gaskets have all been addressed recently enough. Brakes will get a refresh before the start of the season (pads, rotors, Castrol SRF). Pretty much everything else is original. Odo will be around 120k by the start of the season. Tech inspections are a given.
Planning to get a Schroth Quick-Fit, and possibly HANS.
I think most of the events I’ll be doing will be at NJMP, but other possibilities include Summit Point, Watkins Glen, Pocono, and Lime Rock.
Here are the questions I know to ask:
1. Brake pads: Staying within FCP Euro’s catalog, I want as much fade resistance as possible without having operating temps that are out of reach for street tires and stock power. Given those criteria, it looks to me like the best option is Hawk DTC-60. Way overkill, but seems to tick all the boxes. Hawk's mu-vs.-temp curve for it (attached) looks really flat even down to low temps, it'll have all the fade resistance I'll need, and no one seems to have deposit issues with it (unlike, say, Ferodo DS2500). Does this make sense? It doesn’t look like FCP Euro sells anything worth trying, but I’m open to suggestions.
2. Power steering: On one hand, the leaks and failures people have experienced make me want to address them preventively. On the other hand, I’ve read that not all cars have those problems in the first place, and that it’s less of a problem on street tires than on R-comps. Given that, I’m inferring that a CSF power steering radiator and a new OE PSF reservoir should be enough for my setup and expected usage. Does that sound right?
3. Measuring tire and brake temps: In order to make sure my camber settings are reasonable without waiting for pronounced wear, I want to measure relative tire temps across the face of each tire. I have a cheap IR thermometer with an emissivity setting. Is that good enough?
4. Alignment: Camber is around -1.6º front and -1.9º rear. Front caster is 7.2º. Should I dial more in before my first event, or is there no way to know until I start measuring tire temps?
Would love to hear thoughts on all of the above, and anything else I don’t know to ask about.
TIA!
