Knowing what I know now, I would have ran a 245/40/17 at nationals this year and just dumped the car in 3 for most of the courses. Hell, that's basically what we did on the Plane side anyways with the 255/17's
Have a few items from my GS SI. All parts should fit all 2017-2020 Si’s. I’m willing to ship at buyers expense but prefer local pickup in Orange City, FL (32763)
$75 - porterfield R4S autox pads. Barely have any wear after ~15k miles. 16mm of thickness with a 5mm backplate.
$125 - Gloc R12...
You wont find any stats really on this. Just stay within your limits at track events and mind your surroundings and you should be fine. Mechanical failures happen and cannot be avoided. I had a car on car contact in a TT event when my hoosiers corded mid session and whiped the car hard under...
I fit all 4 wheels standing up in the rear seats (using those tire totes). barely see them back there while driving.
If I need to squeeze extra unmounted tires for changing them out, I can do 2 in the front and 2 in the trunk but nothing else fits. When mounted I can only fit 1 in the trunk...
I know of one but they drive ham fisted harsh on the nose.
Mine are at 60 runs, not flipper and they have double the tread depth of my 71rs that have 80 runs and flipped at 40. The shoulders on the 660s look solid still too. Going to do one more event before flipping
Yes, I just found the sedan fugly LOL. They actually have a hair better head room, 6” longer over the rear bumper, ~15# heavier. So basically the same car.
Sounds like something else is wrong here. I don't know exact temps but my gauge never moves at an autox, even mid summer here in FL 95+*. I'd expect the gauge to start to creep at 215-220 range.
Keep car on, pop hood, turn on AC or heat (Heat works better but you'll not be happy lol). Some...
Did not help but think pro solo's hurt it more than anything. I kept getting really bad hop on launch at zmax last year and playing with the rpm didnt seem to do much. Had a bit this year but wasnt as bad on the 660's
started out with a vibration on right hand turns only that got worse and worse then you could hear a vibration/rattle at idle as it died through the weekend.
Im at 60 runs on my 1st set, no issues. I actually thought they were rubbing at the 1st event on them but i actually broke a pass. side motor mount :doh:
