my car is stock shifter + Barton 2-post bracket, Whiteline trans bushing, JHR/JPC stainless clutch line, motul rbf600 fluid. no issues lately with shifting under WOT
MGW if you want to do track. Barton good enough for daily driving. Sometimes I have a hard time with 3rd and 5th and also down shifting into 4th. Thinking about buying a Barton Bracket.
