First off, I drive fairly conservative with an occasional bout of spirited driving. I purchased the NT555R 305/45/18 Drag Radials and mounted them on AM factory style 10" rims for the back of my 2012 Ford Mustang GT - manual trans, daily driver. I have replaced several intake and exhaust components on the car in addition to installing the Ford ProCal tune and 4.30 gears (California car - CARB legal). The rear LCA's and 3rd link have been swapped out, and air bag inserts have been added. Previously, the car would easily lite up the factory 235/50/18 Pirelli's in 3rd and even get 20 foot long, fish-tailing chips going into 4th gear at over 70 MPH! Both, 1st and 2nd gears, were pretty much useless. Traction Control seemed almost non-existent. Now, it hooks to my satisfaction. I will update once I get a chance to make some passes at the track, for the ultimate test. I currently have about one thousand miles on these tires so far. The car handles quite well for a Drag Radial and the wet performance doesn't seem to be an issue. (I was a little concerned about that aspect, since this IS daily driven). The taller height helped with respect to roll out, comfort and mileage. Recently, on a road trip that included a ride over the California Grapevine north of LA, I easily managed 24 MPG. ( I could easily increase this 1-2 MPG, especially on flat land). Current around town (mixed) mileage is at 19 MPG. The car looks good. I am using the NT555 235/50/18 up front.
