I own a GT350R as it replaced my beloved fully prepped supercharged 525 hp Z4M as my track car and it is just fantastic . The money is in the motor , manual transmission , suspension, carbon wheels , 305/315 sport cup 2's and a torsion differential, where it belongs. Best drivers car I have ever experienced period . Destroys any BMW on track time wise and is a better driving experience. Would I like a better interior sure , but whether you rev it out to 8300rpm or are just driving to work it's a special experience. Here is a session from Roebling raceway to show just how capable it is. Beat my fastest time in the Z4M by over half a second despite the Z4M being on Trofeo R's and me still learning the car .
