Tracking parts consumption

[CARMASTERRACE]

Guys
I have an M3 order for a month away from now. I plan on tracking it 2 or 3 times a year, maybe more if I really get hooked to it (I am gonna keep the car for 2 years).

I am curious to see what parts get consumed the most, as to plan ahead for the possible tracking.

Kind regards

just started tracking mine and plan to change the pads to pagid rs29 when these give out.

also think about getting some dedicated track wheels and tyres, far more options available in 18". I plan to use my stock wheels for the track and switch tyres once the pss expire.

Ok. I plan on using my car as stock on track. I haven't considered track tyres, but that might be a good idea. I will think about it.

Consumable in order of importance:

• Tires
• Brake pads
• Brake fluid (will require more frequent flushing; 1/year minimum)
• Brake discs

RS29 or Carbotech XP12 pads will last you two years (4 to 6 days) easily.

Count on 1 set of tires for 6 days although you might get more out of them. If it were me, I don't think you need a dedicated set up for 2 to 3 days a year unless you are an advanced driver. I would burn through the OEM Super Sport tires in the first year and then put on a set of Potenza RE-71R or Yoko AD-08R (or equivalent) tire as that will give you all of the performance you need until you are advanced.

Got it. Interesting comments, thanks very much for the input.
I planned on really going stock, but I will agree on the pads. I had it in my E90 which the first owner gave me with the car as he planned on tracking but sold the car before. When I changed it was way superior. He had bought it from here I believe:

That is an upgrade I will consider. Brake discs I will keep the stock steel, as they are pretty decent.

Now in terms of tyres is the Michelin PSS close to the Potenza RE-71R or Yoko AD08R in terms of grip?
Because each Potenza 71R here costs R$4000 (about US$1350) and it is also very rare to find. Yoko AD08R is also impossible to find, while the PSS is common and costs about R$1600 (US$ 530). Putting a set of 71R with alignment and balancing, would easily cost me US$5,500, which is a fortune to my eyes. BTW I live in Brazil, so don't be shocked with the prices, as they are pretty steep.

Thanks mate, I wasn't aware of the Brake fluid. Pretty interesting. Do you have any idea of how many trackdays the brake discs can resist?

A flush with fresh fluid at the start of every season is a good starting point.

For the discs life, it varies significantly depending on what pads and tires you use, what tracks you run, your driving style, etc... Expect to get between 20 and 40 days for the fronts and usually the rears last twice as long as the fronts.

Thanks mate. Very good point raised, if you did not tell me I would absolutely ignore that.

Good precaution, but certainly not mandatory.

I have been tracking M3/4s for 12+ years on stock fluid and never had a problem.

Wow - maybe the tracks are different? We in socal have lots of high speed braking after another and the weather doesn't help at all. Plus mine is the damn near 3700lbs kind.

With SRF, didn't have to bleed until half a year to a year. With Motul 600 after one and half events. Didn't like that I had to bleed in the middle of the day on only the 2nd day on a so called great fluid.

All the track I go to also have quite a lot of high speed braking too (125mph~145mph range) .

The big thing for brake fluid longevity is to do a proper cool down lap with no brake applications before you come into the pits.If you come into the pits with hot brakes the fluid temps will spike with the heat soak with no airflow.

Mid session - too many hotlaps in a row trying to chase down GT3's and a Z28.

At that low level of usage, I think you will be fine and not really consume anything much faster than street usage unless you are also tracking something much more often or have a lot of experience.

Yeah 140 to 40 then immediately 90 to 50ish then 100 to 30 and so on.

+1 on tires, but as a new to tracking you will consume little at the beginning and as you get better you will burn through brakes and tires more.

and gas.. you are gonna burn gas at the track like no tomorrow

Now that you guys told me about the brake fluid it is something I will look into more often.

What is the difference between the fluids? Or did I misinterpret something.

Near where I live we have the following tracks (which I will be attending)
I will input from the tracks we have here. Temperatures are hot on 90% of trackdays (it's BRAZIL ), and the humidity tends to be pretty low, not sure if that is good or bad.

We have Piracicaba which is a Karting Track used for trackdays. It is a pretty challenging and tight track, not really that fun as any excessive throttle input or mistake = grass or even wall.
This one has no real high speed braking, in fact top speed here is around 150-160km/h (100mph). It is tough to skid around or have some real fun, many go there just to drift, but I have seen 2 cars get totaled there already. Never drove there, just went as passenger. It is a very technical circuit.

The second option is Velocitta - an interesting mix of 2 long straights, a couple of high speed corners, and various low speed S's, and corners. It is 2.2miles long, and best lap time ever recorded was on a track prepared GTR with 1:41.00, I already went here with the ex C63 W204 and M3 E90 2 times, besides driving the W205 and F80 there. My opinion is it is absolutely awesome and full of high speed braking, with my ex W204, I had brake fade on the 7th lap already, and the E90 my brakes were smoking after 10. Pretty challenging but probably the best track so far. Top speed here is about 120mph (190-200km/h), however the corners just after the straights are low speed 30mph (50km/h).

Then there is Interlagos - the most famous which is basically composed of medium speed corners, 2 massive straights, and 2 low speed corners, here it is only high speed braking, easiest track to top out the car, I managed to do 145 with the C63 here and then I had to brake to about 55 for the corner lol. Brakes get eaten pretty damn quick.

The other then is Capuava. Full of speed low corners, short straights, and 2 high speed corners. It does not have events often, and braking here is mainly medium speed. Max speed is about 110mph (180km/h). It is a challenging track.

Those are within 100miles to my house and they are all good options. Having driven in all I believe Velocitta is currently the best, and Interlagos second.

I really enjoy trackdays and I have gone to several, but it is too costly, and my wife prefers to spend these throwaway money into travels, and other stuff.
Therefore I would really like to take the M3 to every single trackday, but it would not be worth it, especially considering I go karting every week.
