Before heading to Barber, changed the setup a little bit to hopefully avoid cutting the tire again.
Put stiffer springs in; moved the 7" 650 lbs springs from the rear to the front and got 6" 700 lbs springs for the rear with #171 tender springs from Vorshlag. Also raised the car about 0.5" just in case.
Did a 1:44.31 at Barber (compared to previous 1:46's) and the driver front tire got damaged on the inside again, this time in a more dramatic fashion (but still held pressure!). At this point, I believe extra g's from the aero must be stretching the tire sideways enough to contact the spring. Ordered 25mm spacers to replace the 20mm I have now and hopefully the problem will be solved.
To add insult to injury, had a small off into the grass and damaged the splitter. I knew the splitter would get damaged at some point, just hoped it would last more than 2 hpde's.
Time to build a custom splitter, one that does not require removing the front bumper.
