Time for Tires

For the street I don't have a street spec - just plan to go to the dealer and have them put it to standard Z/28 settings - which I don't have - see what they have to say an go from there.

Any alignment specs from the dealer? Track and street specs....

This set up is using 305 30 R19 Goodyear 3R tires on factory wheels for track day. I will be using this same set up with slicks next weekend at COTA. I no longer bother returning the car to a street alignment. Street tires are 305 30 R19 Bridgestone Potenza RE-71R on factory wheels. What works for me and how I like the car to handle on track may not work for you. The track alignment was not performed by a dealership. Please note the lack of toe in, it is not for everyone. I also have Vorshlag camber plates, ZL1 addons 5mm spacer plates up front and several adjustable DSE suspension components on my car so if there is a part of the alignment shown here you are not able to achieve with the factory components this would most likely be the reason.

I just had my car looked over and checked out. Also had track spec alignment done. I've never been to the track but hoping to go in the next few weeks. The car tramlines a little more on the street, nothing major. But turn in feels much quicker. I have a trash Pirelli Pzero's im running until they wear out (still a rookie lol). These tires are major weak point. No bite in the front and no traction under throttle.
