Yokomo Works 91 rere performance and reliability package. A discounted parts bundle to replace the original plastics on your car for racing, to avoid breaking original parts. All the parts have been race tested and remove the excessive slop from the suspension as the hingepin holes are all hand reamed to size. The bulkheads correct the front arms castor to 12° and the rear to 2.5°, whilst also introducing a rear belt tensioner. The front bumper is shortened by 1/4", so instead of digging in on a nose landing, the car will land on its wheels, which was a common mod on the original cars. Bundle includes:

Shortened front bumper £15

Front arms £25

Front uprights £12.50

Front steering knuckles with M3 inserts £13.50

RPM style front bulkhead £40

RPM style rear bulkhead £40

Rear uprights £10

Rear arms £25

Replacement one piece centre pulleys £5

Total is usually £186 so there is a saving of £37.00 over buying separately.
