A Mazda 4.30 differential crown wheel and pinion set for the rear differential. Fits several cars such as Mazda pickups, RX7, Kia Sportage and Honda S2000.
For an atmospheric engine such as the S2000 and MX5, a differential ratio increase is very effective. This allows you to take more advantage of the vtec/power zone because the car can stay higher in the revs. Your practical top speed also becomes higher because you can drive towards it in a lower gear.
For the MX5 NC, a crown wheel spacer or Honda S2000 differential/lsd is required for installation.
Please contact us for installation costs.
Attached is a diagram showing theoretical top speed per gear by differential ratio.
