Race Tracking Your Supra - Information exchange

[Gabe]

I use racebox that does a similar thing

I have it too. It’s what I use. Is very simple to set up and I like it, but lacks in a lot of functionality that the Garmin or another platforms have.

I never used the Catalyst to compare, but I know there is a lot of Catalyst at the track, people seem to love them. Unfortunatly, I wasn'T ready to pay the price

Engine oil every event or two is a bit over kill. I used to be like this but having done about six oil tests with the Supra, if using a good oil like Motul 8100 x-cess, you can easily do four-five. Hell, I had six on my last test and the test came back fine with good viscosity still.

I would change your diff fluid if you haven't yet. It's very easy.

Do you use any specific brand/type of diff fluid? What about trans fluid? I was thinking I should change my trans fluid too before the start of next year's season.

The one big thing I like about the Catalyst is the ego feeding feature of the leaderboards. Well, that and comparing laps with others.

Like Kyle, Peter, and myself in the top 3 slots for the season at Lime Rock. Viva La Supras!

I use Motul for the rear diff and OEM for the transmission.

Considering Titanium exhaust for track use, as there r some BF deals. Its not about power coz stock is enough for my power goals, but Ti supposed to be 17kg less (id be around 50kg less overall on weight all parts added) + have some nice sound since stock car is silent... Looking at Whifbitz titanium exhaust: https://www.garagewhifbitz.co.uk/product/garage-whifbitz-3-5-titanium-exhaust-gr-toyota-supra-a90/

Should i be worried of it cracking after some time driven in extreme conditions? I red a lot over the net about titanum exhausts having problems esp on welds and that they have accelerated wear if track driven...
@FLtrackdays didnt U have problems or im mistaken?

Yeah, titanium wouldn’t be your choice for tracking. The AWE Track exhaust (like most other “track” versions) uses T304L stainless steel, which is more durable and less prone to cracking than titanium. Titanium has a slight weight savings advantage. But stainless steel is tougher, more rigid and better resistance to thermal fatigue. Why I had mine welded in one area and called it a day.

Noob question, but should I always use new bolts on the rear caliper when switching from street pad to track pad and vice versa?

They are not torque to yield, so you don’t need to.

Finished my first track season with the Supra at VIR this past weekend. What a great track!

I did 5 events, and will probably do the same next year. For you veterans, what maintenance do i need to do and when? Brake fluid flush, of course. I change oil every event or two. I have spare rotors ready to go, though I may not need them till next year (inspecting them regularly). Do I need to do....diff fluid? Something else? Thanks!

Sounds like we do about the same. 6-8 for me if I’m lucky. Diff & brake fluid at the beginning of each track season. I can “bleed” off the dirty brake fluid (using Castrol SRF) between track weekends. Pads, tires & adjustable bolts you just have to watch. Eventually you’ll go through them quicker than you’d like. Engine & cabin air filter annually. Alignment beginning of the season or when you feel something off.

engine air filter anually?

Now I know why you guys just do new rotors with new pads. I wired wheeled the stock rotors and installed the club racer pads. Bedded the snot out of them a month back and 2 hot laps into the track day today and they were shuddering like crazy.

 

[Rob_SER]

I'm so happy reading I'm not the only one. My mind was blown earlier this summer when this happeded

 

[tomfree]

This has been my rule for the last couple of cars - if I'm changing pad compounds, I'm changing rotors. You don't "have" to do that, but I don't want to think about it. It sounds like the PMu Club Racer's aren't happy with another compound in the rotor - moreso than others.

Might as well rename this thread to "let's talk about brake shudder and how I am not able to properly bed in my brakes"

Didn't realize 1 post and a couple replies on a subject warranted shitty remarks. I take everything you post as incredibly helpful, truely, you're a massive asset to what i do to track my car. This has been an incredibly frustrating portion to a newcomer such as me so hopefully others can save time instead of throwing away a couple track days as i have.
