Question recommended maintenance for HPDE events

I'm looking for recommendations on what, if any, preventative maintenance I should perform before my next HPDE event. Of course my number one concern is safety. So far my car has performed flawlessly at the previous 3 events, but given the extreme duty, I want to make sure that I stay on top of the maintenance. However, I don't want to go overboard either and waste time/money on things that I shouldn't be worrying about yet ...

Background information:

Car: 05 STi with 10K miles

Mods: TBE + EcuTek flash (290whp/315wtq on dynojet), Pagid Blue pads, SS brake lines, Motul 600 fluid

Track exposure to date: car and I have been to 3 HPDE events at Summit Point last season (2 FATT + 1 PCA)

Maintenance history of car:

- Oil and filter changes performed by yours truly every 3K miles (either Red Line 10W40 or Mobil1 5W30)
- Brake fluid was flushed and filled with Motul 600 when the pads were installed (after first track event)
- that's it ...

Possible issues: brakes are squeeling something furious during normal driving ... pads and rotors look ok though, pedal feel is fine, no vibrations ...

So, should I:

a) worry about the brakes given the noise?
b) bleed the brakes before the next event? (brake system has seen 2 events without any service)
c) do anything with tranny or diff fluids?
d) check anything in particular with the suspension?
e) anything else at all?

In general, what extra maintenance do folks perform when attending HPDE events and/or what accelerated maintenance schedules should I apply?

Thanks!
Josh (budding track junkie)

no, high perf brake pad are noisy and dirty.

yes, and depending on the track, you may want to bleed them between sessions and or days.

maybe, Redline Shockproof Lightweight works well.

yes - you should make it a habit and keep a check list of things to go over (e.g. wheel bearing play / issues)

maybe - might want to run a higher octane on track for added protection from knock.

Thumbs up

^^ +1

as zzyzx said the pads are probably okay, higher performance ones will make a good bit of noise when on the street (and not up to temp).. But just to be safe (and b/c it's easy) I'd pull the pads and make sure you have at least 50% of the pads left..

definately flush the brake fluid - no reason to boil the fluid if you can avoid it..

definately change the differential/tranny fluids, the first change of the diff fluid will yield some nasty crap stuck to the drain bolt.. I used Redline NS 75w90 in both of mine, and it feels much better then the mobile1 I had used in my old WRX wagon..

checking the wheelbearings is a great idea (they'll probably check them at Tech)..

Depending on the temperature where you're located I'd change your oil to a 5w40 full synthetic (either Mobile1 or Shell Rotella). I never run 2 events on the same oil..

not sure what your tires look like after 3 events, but you'll probably want to rotate the fronts to back (if you haven't done that yet), check all the pressures, and the lugnut torques (I keep mine at 85lbs)..

Thanks for the responses.

Yeah, I expect more noise out of a higher temp pad, but still the Pagid Blues are not really an extreme track pad, are they? They didn't make that much noise until after the second track event. Maybe they were just breaking in .

I had the car at a local shop (Curry's Auto in Sterling, VA) to switch back over between my Winter tires (Nokian WRs) and the stock RE070s and they noted the loud squeaking. However, upon inspection claimed that the pad and rotors looked nearly new. They are supposedly familiar with these pads and think that they shouldn't be as loud as they are. They couldn't figure out why they were so loud, so I guess I wont worry too much.

Is there a good checklist somewhere that you know of for me to reference? I'm just getting started on trying to perform my own maintenance, so a lot of this is new to me. I'll still probably take it to a shop for the critical safety items, but I really want to learn to be as self-sufficient as possible (mostly because I have a hard time trusting anyone else to do things right and I'd rather save the money for more track time )

Definitely. They offer 100 octane unleaded at Summit Point and I run that exclusively when at the track. It's pricey at $5/gallon, but it's worth the peace of mind I think.

Yeah, I've had good experiences with Red Line fluids in the past, so I'll probably make this move.

I've watched them tech my car at previous events and they seemed, well, less than thorough to say the least. They do grab the top of the tire and pull outward a bit, I guess this is their bearing check? Is there something more that I can do?

Yeah they are fairly well chewed up There is a decent amount of tread, but quite a bit of chunking has occurred. I figure they have at least one or two more events of service to provide. I decided to go ahead and mount them back up as opposed buying something new (still trying to figure out what to buy next). Call me crazy, but even though they're a bit heavy and can get greasy after a few laps, those RE070s seemed to perform extremely well for a stock tire. Honestly, they probably meet or exceed my current driving skill level

Thanks again for the tips,
Josh
