Race Tracking Your Supra - Information exchange

Me…. Who has NEVER bed brake pads, Reading all this talk about rotors and pads… while installing a used set of 345 mm rear rotors and calipers and fitting new Hawk DTCs 60 and 30s front and rear.

Since Hawks are generally tolerant of other pad compounds, you're likely gonna be fine. One of the old solutions for pad deposits on otherwise good rotors was to drive around on Hawk Blues for a few miles to clean your rotors, and then bed in whatever new pad you wanted.

If you guys think DTC60s and DTC30s make a mess of your paint...Hawk Blues laugh at you. The dust rusts when you look at it wrong and manages to be corrosive at the same time. Hawk still makes them, they're cheap, and they like heat. They are treacherous on the street when cold. They're the epitome of old race brake pad compounds.

Laughs in IronX.

Sir, did you not get the memo? 9 out of 10 interneters believe that running thicker than 0w-20 will cause world food shortages and the third coming of something apocalyptic. Nevermind that myself and others have proven this false by actual real world data.

Went ahead and said fcuk it…. ordered the entire Verkline front end parts bcuz of you ?. The replacement bushings SPL sent are tight (to spec) for now & should get me by for the weekend ?. Understandably even metal bushings will wear over time. But this will be a piece of mind that I’m starting over again with Verkline ?

I couldn’t afford the rear end yet but have one Verkline part back there, mixed in with the SPL ones, holding it all together ?

I remember moving up the Hawk blues thinking I was such a badass (back in the day - damn I’m old) & that compound will last me forever!!!! I didn’t even know they still make it….

CRS sizes + actuall thread widths if any1 is interested. Last column is used rim width for measur.ent.

Three things I noticed this weekend at Homestead.

1) Adding some toe out up front helped tremendously on track. I believe the shop added 5 minutes of toe out per side up front (about 0.16 degrees total). It might have been more but I couldn’t remember how much total he said. The rest of the specs they kept the same. Rear tow in total about 0.2 degrees, and negative camber approx -2.7 in the rear & -3.5 up front, for our flat Florida tracks.

There was visibly less scrub on my outer front tires, turn in was much quicker (removing some understeer) & felt much more agile. I drove quicker than the previous weekend (even w/out being in TT). My optimal lap time on the Catalyst is now much lower. So I’ve got a lot of room for improvement - quicker lap times ahead.
*(This obviously wouldn’t be ideal for street or those just starting out)*

2) The xHP transmission flash, stage 2 was great but stage 3 was even better. Thanks to everyone who suggested to do it and @Ruman‘s trackside help setting it up!!

3) I drove @Gabe’s mean track machine ? Wow…. his car is no joke. Dude is on the right (build) track!! Looks even better in person AND rock solid going fast ?. The downforce and seats were track bliss. I could have pushed it harder - but he was in the car with me ? lol. Normally we all know you should put experience 1st & foremost…. But in his case, if you’re able to do it, can fix it yourself, and can afford it - Amen - Enjoy it!!!!

Unfortunately now I have to bite the bullet and get a proper seat. It felt too damn good being back in one again. We weren’t alone btw…. few other Supra owners (below) who also now have the track itch, thx to NASA & Toyota‘s free track day.

it was really awesome to get to know you and get some of that experience.

Riding shotgun on my car was an eye opener! (THANKS!!) I didn’t think a Supra could be driven THAT fast and sharp. Can’t even imagine how it should feel going all out on it! (That felt kind of all out to me tho)

this was my first track weekend so my focus is to learn the line and the braking / throttle points. Going slow I think I got most of the corners except that “S” turn where the yellow tires are…. I’m all over the place there. I think I got it so-so only once in the entire weekend!

because I’m so slow, I’m not using any of the downforce, but maybe in the future!.

Looking forward to meet again , it was definitely a blast!!!

New external oil cooler option:

Supra GT4 also uses external air to oil one as far as i remember.

I really want a Wagner manifold next. Dammit, after a seat I mean. Man I hope that’s not something else I‘ll be needing (wanting) ? I love Verus products! Mega high quality and unfortunately high prices to match ?

Totally hypothetical… thinking down the road (after the seat & Wagner manifold ofc). Do any of you think I could run a MHD stage 2 flash if I sent my ECU to FEMTO? I currently have a catless dp and want to keep running 93 octane for simplicity sake. That kind of power gain would be insane imo.

What makes you think you couldn't? I'm currently running MHD stage 2 with catless DP 93 and really like the map switching for track. Since I'm new to HPDE and RWD in general I set it to 85% power which is roughly stock boost levels to help learn. I used the full 100% map one session at VIR and picked up 6-7mph on the straights. Definitely worthwhile investment but I would also like a IM for the higher boost levels, eyeing the Do88 MERA.

 

[FLtrackdays]

Couple of things, but mainly not overheating or going into limp mode if I push the snot out of her on track. I like that she’s currently reliable and can drive to the track & back. I lack tuning/ software knowledge to self repair or diagnose suff that could possibly come up. Unlike some of you guys.

Right now I can get my times down further with my current power. But it’s definitely worth considering if overheating isn’t an issue with a manifold & engine components can handle it.

The little JB4 worked until I got more confidence in the car and started to really push it. Didn’t know if that’s the same case here.

 

[Rob_SER]

well, you mentionned you wanted an upgraded manifold, so that's taken care of, no?

Do a seat 1st I did recaro pole position, more comfortable than stocks for me.
I got wagner manifold waiting for install too + may do this verus oil cooler so I'll have all cooling in check forever (esp for higher power goals down the road).

 

[razorlab]

For those sticky hot humid Florida events, I would do manifold + oil cooler. Would be pretty set.

you'll want to route the lower belt through your lap belt hole on the driver side, otherwise you might submarine in a crash
