It is a beautiful GT!
You might want to consider either changing out those tires for a less-sticky DOT compound, or having your rear quarters that are exposed to the flying debris, clad with a 3M Clear Bra material.
Race type tires look great, but are absolutely the worse trash magnets you can imagine..

Race tires aren't too bad cold but when the compound is hot, they are like glue.

I always found them too hard and slippery when cold - but it didn’t take much of that sliding around to get them sticky….

Cold they have little grip- you are right about that1 I had an interesting phone conversation with the chief compounder at Goodyear Racing Tire Div many years ago. I forget his name- he was British fellow. At that time the optimum tread temperature was 190F.

That concurs precisely with the information given to me by the tire engineers at BFGoodrich when I was driving under contract with them In the late 90’s…. Their compounds were formulated to start working at 180°f and starts to fall off over 200°f.

IMHO, if the use of racing tires on the highway is just an invitation for trouble….

They don’t make radials in this size therefore there is only one option. I will be fine, I know how to drive on race tires. This gt 40 will get tracked as well hence the set up.
 
Ok, so far I have put over 100 miles on the car, and all I can say is I have a per-ma-grin!!!
The motor revs so fast, and is so fun. The car rips, once you hit 5k on the tac, it vibrates windows of cars your passing.
It's just crazy how much fun this car is.
 
I have about 600 miles on the GT 40, and I am not getting the best gas mileage right now.
I know some people were concerned about the avons being race tires on the street, but these tires have amazing grip to the point you really would have to try to spin the tires. I am having so much fun driving this race car with a licence plate. I still can't believe they let us have these on the street.

Olthoff has been great to deal with, It took a little bit longer than expected but well worth the wait.

Have you pulled the spark plugs to read them to see how you are running or a way to look at your air fuel ratio while running? Unless it is a right foot issue, I would expect decent highway mileage.
