At the Track Fairly new to track racing... need some help/advice/guidance.

Basically as the title says... I'm new to the racing environment. Went on my first track day yesterday and I feel in love. The car felt fantastic, but I've got a few things to iron out before going out again.

My car is a 2005 STI. Mods include: JIC coilovers, whiteline front/rear sway bars, Cobb Stage 1, 4 point cage.

My questions are this:
  • What brake pads should I be using?
  • I've heard to flush out the braking fluid for something more aggressive… what do you guys normally go with?
  • What tires? Ideally I'd want something that I can drive to and from the track as well (1hr away).
  • Anything else I should be doing?
  • Oil? Mobil 1 5w40, 10w40?
+ any other advice you can give me.

I plan on hitting the track up at least 1 or 2 a month.

Thank you!

You are going probably going to get a multitude of opinions in your thread but here are some that will help get things started off.

What brake pads should I be using?
Your going to have to find the pads you like as you go along and experience different ones. Read around some threads can give a good starting point. Since I suspect you will be on nothing more than sticky street tires I would suggest starting not going right into the race specific pads since you will be learning how temps are involved (plus you need to change those out for street pads when DDing). Move up in pads as your experience evolves and your needs change.

I've heard to flush out the braking fluid for something more aggressive… what do you guys normally go with?
By more aggressive they mean able to handle higher temperatures. Motul 600 and ATE blue are popular fluids. I personally use Motul 600 and flush bleed fresh fluid through the whole system before a trackday. Bring some extra to the track (plus bleeding tools) and be prepared to do a quick purge in between sessions if you over heat the brakes and you find them squishy.

What tires? Ideally I'd want something that I can drive to and from the track as well (1hr away).
An ultra performance street tire will do fine for starting off. Same thinking as brake pads, you will get a lot of opinion and will learn from trying different tires. Just be prepared you will wear out tires faster than you think. You want tires that can handle some heat before they grease out on you, but hat also has a lot to do with how you drive too. Ask someone at the track to show you how to set tire pressures based off tread contact, I use one of those foam shoe polish sticks.

Anything else I should be doing?
Get as much seat time with an instructor as you possibly can. Get as much seat time with an instructor as you possibly can. Yes I repeated that one for a reason. Learn track rules and etiquette, very important. Avoiding picking up bad habits like signaling a pass without lifting. Track days are not about being the fastest it is better for learning the track, figuring out the good lines, and driving like you wish you could on the street. I feel if you can't talk to the instructor while driving you are pushing it too hard. Slow and steady is best. Watch out for others it is only a matter of time before you see someone veering off track in front of you due to pushing it too hard. Don't be in a hurry to change parts on your car until you understand that there is a weakness and what parts will actually improve it.
**Forget adding all kinds of gauges. You should be paying attention to the track and your driving technique rather than watching gauges. Besides you not be racing or pushing your car to the limits at a track day.**


Oil? Mobil 1 5w40, 10w40?
Just keep your maintenance up to par and use an oil that will handle severe duty (most will) usually a synthetic. I run 5W-40 synthetic but have ran with 5W-30 synthetic as well.
**The only precautionary upgrade I would highly recommend is a Killer B oil pickup tube since you will be subjecting your engine to additional force and vibration.**

Oh and make sure to have fun!

Make sure you have the updated rear brackets on the JIC coilovers. The older design had a habit of failing catastrophically. Even with the new brackets, I'd check the lower housings carefully for cracks, and check them often.

Do you have anymore info on this? I'd like to make sure that I've got the updated bracket.

Dunlop Dirreza star specs are a great street tire to use for Track. Learn the safety of the course first i.e. flag stations, passing rules (if any), Flag meanings. Seat time is the best, i always took an instructor if they were offered and always learned more. As you do more you will find out what type of changes you wanna make. Have Fun and Be Safe.

My setup:

05 STi Time Attack Project Car
Dirreza Star Specs
Motul RBF 600
Motul 15W 50
Hawk DTC -70 (track only Pads)

I started with StopTech pads + RBF600 Fluid. works well as you get into more seat time.

Cooling hasn't been mentioned. A good aluminum radiator (like a koyo) filled with only water and water wetter will go a long way toward keeping the car happy on a long session and/or when it's hot out. A real coolant temp gauge would also be a good idea.

Dunlop Star Specs and Carbone-Lorraine RC5+ is my favorite street and track combo. Both the tires and pads will survive track duty without issue, and they are both quite usable on the street. This setup usually lasts me a full season, with about 7 track days and ~18k street miles.

Any DOT 4 should be fine to get you started. The RBF600 is king, but ATE is the most common at the cheaper end. Using titanium shims, I never had a problem with ATE, even when my rotors were glowing (before I figured out the right pad).

You should definitely throw a bottle of water wetter into your coolant mix, whatever it is. That stuff works wonders. If you don't need to run glycol, you shouldn't. If you can run a higher percentage of water, that is also good. I run a 40% glycol mixture (plus wetter), which still gave me some margin knowing the car would see -5F in the winter.

Other things I have gone after were for reliability, mostly engine. Oil pickup, oil baffle, better radiator, oil gauges.

+1 Star Specs, ATE Blue, DTC 60s and brake ducts for me.

Concentrate on braking and engine reliability for your vehicle these first times out. They will save you cash and heartache over the life of you car.

For engine reliability I would suggest oil temp and pressure and coolant temp gauges. oil baffle, better radiator, an Crawford AOS, oil cooler. that should about do it for starters. Of course, the mods are endless.

I've run Rotella 5w40 at the track without problems. Change it before and after.

Are these pretty much toast, or is there another track day in them? Got them on another set of wheels.

For now just starting out just get some good entry level track pads (carbotech xp8's or some of the other ones mentioned already)and a good dot4 brake fluid flush.

Heat destroys these engines as well as oil starvation. Anything you can do to keep the car cooler is a good idea from running water in the radiator with water wetter to heat wrapping exhaust components and parts of the intercooler and/or switching to a front mount (not nessecarry at all but an option none the less.)

In my personal opinion you want to upgrade your oil pickup and windage tray in the oil pan at the very least if you plan on tracking the car regularly and you're driving on sticky tires. KillerB Motorsports makes great products and you may want to end up buying their oil pan/pickup/windage tray combo if you can. I ran motul 300v 10w-40 in my STi. It held up great to track days as confirmed by used oil analysis even in the 100+ degree texas summer heat.

I'd run them but that's me. If you have the room why not bring em? Most run blanks that are equal to centric premiums. Fancy slotting and such just reduces mass and heat capacity at our level of play.

I went to my first track day yeaterday and had a few of the exact same questions afterwards. Especially relating to brake pad/fluid upgrades. Great thread, I'll definitely be keeping an eye on it!

Yoshi, make sure you check out 3Balls Racing dot com, the group will be @ Grattan (Belding, MI) for a two day HPDE July 28 & 29th. There are several STi's that run with that group and any of them is more then happy to give you advice.

Also they will be @ Gingerman next weekend as well.

You can replace your stock pickup an baffle without buying new pan from killer B. it will save you alot of money.

I'd spend the money on the oil pan. It's a good investment for sure and a nice unit.

New question... I'm going to be replacing the transmission and differential fluid before next seasons starts. What do you guys recommend for heavy use? Stock stuff, or something better?

Title change to "Fairly new to HDPE Track Days...need some help/advice/guidance" would be good, since there isn't any racing going on.
