I had a Megan, felt an OBX, went back to stock because I couldn’t stand my Megan, spent the $ on a B&M, and the B&M on my S13 actually felt BETTER than the shifter on my G coupe. I’ve also felt a Bing’s shifter, and it was pretty nice, but I could definitely feel a difference between it and my B&M. Then again, the B&M is double the price, and I wouldn’t say it’s twice as good.
It depends on what you’re looking for in a shifter, but the B&M was by far the most satisfying mod I’d ever done. It made the car much more enjoyable to drive.
