Thanks for your input on tires. The GT-R has huge wheel wells to fill, so I want 345's in the rear. That appears to limit the choices. After reading the reviews, including comments about tire noise, I decided to go with Nitto Invo 345's on the rear and 285's in the front. I hope it will turn without hitting the bodywork.
Just waiting to hear about the delivery date. I do not want to hurry it because I have asked Fran to attach the engine/clutch/transaxle/starter motor on his end, as well as the water pump modifications needed to run the coolant lines. I am new to car building and want to respect my limitations. Also, South Florida does not have the fabrication capabilities I had when I lived near Detroit. I have a great shop right next door to my shop in Naples, and they can fabricate the custom headers, and really help me out with whatever I run into.
I have a camera and tripod ready and waiting to document the build. Then I will know what to ask.
