Funny I also snapped a thrust washer at Inde and it led me to getting the GT350 axles so I get rid of them. Driving the car with the dash a christmas tree is doable but not fun (in my case it heavily ramped up the booster so the brake pedal had...
Are the GT350 axles required to remove the thrust washer? I read that people are just removing it, then torquing the axle nut about 200 ft-lbs with red loctite (over the specified 100 ft-lbs + 45 degree arc) and adding a witness mark to keep an... (see full post)
Can report back now after 2 weekends of using the KPM pump at Chuckwalla and COTA, I have ran the car down to 1/8th of a tank and have not gotten any fuel starve
It's mostly a question of life. If you don't mind bolting them on, Trofeo's are as good as anything. I wouldn't be that concerned with a difference in lap time. OF COURSE the longer wearing tire will be slower. I'm sure there's a tire 3 seconds... (see full post)
Some people are easier on tires than others. Some overdrive, some drive off the rear, some tracks murder certain tires (Gateway Roval is my home track). Yokohama are not tolerant of these things.I suspect that the Pirelli might work well for...
The old standby Goodyear SC 3R is right there with the trofeo, Hoosier TA, R7 etc. in most tests, and I believe the 2026 USAA GY discount is 25 percent off. Plus the 3R is a more affordable tire even before the discount. You can get a whole set... (see full post)

This is how my Front A052 looked like after today track day (104 laps on them / 193 track miles and 1933 Street Miles). I did 5 new PBs with them and they still perform reasonably well. I think this tire handle abuse very well.

Even with the 11" all around, 305 is likely the better answer long term (with all the cambers). Obviously best answer is use what you have first, then racer math says lighter 11" wheels "save money" :)There are about 900 better performance...
regular ol' jack and jack stands for me. I am looking into the quickjacks though because if my wife starts tracking soon (which is the plan) I want the time saver if i have to work on 2 cars.
I understand. There just are not a lot of comparisons out there with the Trofeo RS, so I shared one I had seen. There is another one by the Tyres Review guy, and the Trofeo RS beat all of the others in that one, too. It really is a great tire... (see full post)
I am not sure I see Trafeo RS and Nankang even in the same class of tires for that test (which I did not watch) The Trafeo is 180TW, right? And really an aggressive 180. The Nankang is a 200 on the endurance end of the scale. And not that TW...
Some base everything on cost. Look at all the chinese crap last 40 years. Price is a factor but in the world of quality and performance cheaper is not better. If there is a reverse polarity vortex somewhere where this is true let me know.I had... (see full post)
