I recently purchased the BOFI Racing MK1 MX5 Shifter Rebuild Kit with Beatrush Uprated Bush, and I couldn't be happier with my purchase! The kit includes everything you need to rebuild your shifter, including self-lubricating bushes and spring washers. The new bushes and washers make the shifter feel much tighter and more precise, which is exactly what I was looking for. The Beatrush Uprated Bush is a significant upgrade over the OEM Nylon shift bush. It's made of metal, so it won't stretch and wear nearly as much over time, and it's specifically designed to reduce play in the shaft when changing gears. This is a must-have upgrade for anyone looking to improve their shifter's performance. The kit also includes a detailed instruction manual, which made the rebuild process a breeze. I was able to complete the rebuild in just a few hours, and the results were well worth the effort. The shifter feels much tighter and more precise, and the car is much more enjoyable to drive. I also appreciate that the kit includes all the necessary parts to completely renew your shifter, including the lower shift bushing, upper shifter pivot ball bushing, lower shifter pivot ball bushing, smooth wave washer, and tabbed wave washer. I highly recommend replacing the upper shift boot when rebuilding your shifter, as it can help prevent excess noise and smells from entering the cabin. Overall, I'm extremely happy with the BOFI Racing MK1 MX5 Shifter Rebuild Kit with Beatrush Uprated Bush. It's a high-quality kit that delivers on its promises, and I would highly recommend it to any MX5 owner looking to improve their shifter's performance.
