NSX-R 4.23 R&P

NSX-R R&P gearset

In Japan, a special performance tuned version of the NSX is available. The NSX-R model includes a higher ratio final drive gearset that increases the normal NSX 4.062:1 ratio to 4.235:1. This modification results in noticeably faster acceleration times. Performance chart available from NSXPrime. Includes all required parts (pinion shaft, ring gear, oil gear). Also includes parts to upgrade your differential to NSX-R specs.
