I’ve left them on for over a month now and they’re quiet for the most part. More quiet than the Pagid’s were. If they stay this quiet I might not need to go back to the stock pads this winter.
I mount/balance all my own tires, and there's a pretty direct correlation to amount of lube used and amount the tire will slip. The RS and RZ are both somewhat stiff tires so if the shop had trouble mounting them they may have used more lube. Nothing bad, and not much you can do about it other...
I didn't when I swapped them in. That said, I had some shudder in the first session when I went to VIR last month. I had tried doing some basic pad bedding before, but evidently didn't get enough heat through them on the street to do a clean/bed. I had gone from Pagid to stock to PMU 999's...
This. -3.6 with zero toe front works for me, but if I could I'd run -4.
I will say I might go down from -2.5 and .2 degrees of toe in per side rear to -2.2ish and .1ish degree of toe in per side. The wear on the tires from VIR showed I wasn't using the rears as much as I should have, so I'd...
No, as stated I have stock arms. When I installed the plates I push them in until I can feel the top hat rubbing on the shock tower, then very lightly pull it back until it doesn't rub.
Like DC5UPRA said, it is likely due to camber gain from the lowering springs.
As an anecdote, I got a...
I really enjoy the stock shocks for what they are. My setup is just Verus camber plates, H&R lowering springs, and a front bar. Everything else suspension wise is stock regarding arms and links. That setup is good for -3.6 ish front and -2.5 rear while hitting the toe I want. It hasn't...
They may come from the same place (what doesn't these days?), but are a bit different since they use an allen socket to tighten them down vs the motorsports hardware that uses a double nut. Either way, mine didn't have burrs on them and the threads were fine. Other than cleaning them of any...
I liked it a lot and felt like it calmed the car down for mid-corner throttle application.
I did a full write up of my test day here: https://www.supramkv.com/threads/race-tracking-your-supra-information-exchange.16389/page-295#post-556913
The important bit (assuming you don't want to read...
For wheel studs, I bought the Apex ones when they were on sale last year. They've held up just fine for the 20 or so wheel changes the car has seen since then along with 6 track days.
I also found the 275 square to be pretty lively, both on stock tune and with the MHD stage 1 tune. Still very...
The 93 tune was fine in terms of temps (120-130 on the logging app) until ambient went over the low 70's, with boost targeting 16 psi. The E40 map with it's high target definitely dumped a lot more heat in.
I expect when it hits summer here that I'll have to monitor the temps a lot more on the...
I ran a small tire and tune test for fun this past weekend at VIR. First two sessions I ran 275/40/18 square Yok A052's both on an MHD Stage 1 93 tune. Then I swapped to staggered 71RZ's, same tune. Finally I swapped to E40 on the staggered RZ's.
The RZ's were 275/35/18 front and 295/35/18...
Got to run with NASA this past Saturday at VIR again. Sadly, no clean laps, and the best lap was the first not even flying lap during the last session of the day.
Was able to set a new PB of 2:03.5. The Garmin said a 2:02.2 was optimal, but I think without traffic I could get to a 2:01.X...
I got to drive WWT last year during One Lap, and was also happily surprised at how fun it was. I've driven Charlotte Motor Speedway and Nashville Super Speedway so I wasn't expecting it to be as fun as those, but I think I'd at least rate WWT as good as NSS, if not slightly better.
With a 10mm-15mm spacer up front, yes. It'll fit without a spacer in the rear, but I use a 12mm spacer out back to bring the wheel flush.
On a 275/40/18 you'll want the 10mm spacer. If you use a 275/35/18 you can get away with a 15mm spacer (that's where my range came from).
Buy the cheap...
Beyond the MT vs AT data difference, the fluid in each is different and I have to imagine the manufacturing of gears has gotten better than older stuff.
My only temperature data points for MT is from much older cars that had mechanical fluid pumps inside to keep the gears cool. We generally...
I run the 275/40/18 Yok on an 18x10.5 +35 wheel with a 10mm spacer that makes it effectively +25 and it's fine. I also have H&R springs, camber plates, and the same tune. I do have an Eibach front bar that might help keep the tire off some, but I never tracked it on the stock bar so I can't...
I haven't removed the spring perch specifically, but I have done a lot of similar things. Definitely use a real hammer, and work your way around like others have said. If you can't reach the back to impart similar force then see if you have something that can act like an extension (pry bar...
I was also quite sad to see Pitt Race go. One of my favorite tracks so far and easily worth the 9 hour tow for me were it still there.
I think I figured out part of the issue of why the car was more tail happy there. The rear toe had slipped some. When I reset it and then swapped to the...
