This new design shares most components between the Billet RSX Shifter Rev 2 and Race-Spec Billet RSX Shifter Rev 2. The only difference being the center union. The Billet Shifter will allow you to rotate 10 positions to better suite more drivers while the Race-Spec version will have a stronger elbow. If you are drag racing or an overall aggressive shifter the Race-Spec version would be better suited. The Rev2 features some refined and tweaked overall performance to give the shifter a crisper and smoother feel. Some weight has been taken out of it while increasing overall strength. 

Vehicle applications: 01-05 Civic (ES1), 01-05 Civic (EM2), 02-06 RSX, K-swapped 88-00 Civic & 90-01 Integra (using RSX or EP3 transmission)

Note: Shifter arm does not clear shift boot in RSX, EM2, and ES1 on 6spd transmissions. If you want to retain the stock look and boot you should use the regular K-Tuned billet RSX shifter.
