SpectreCodename for Phantom III Rear Road Spring Poundages. SpectreCodename for Phantom III III Continental Saloon which is now running in France is fitted with 1220 lbs. rear road springs. This brings the buffer clearance 4" with 4 passengers. The drawing buffer clearance is 3.900". We suggest therefore that rear road springs should be ordered to the following poundages - 1250 lbs., 1300 lbs. and 1350 lbs. Past experience shows that spring poundages generally increase, so it will be advisable to order most of the highest poundage springs. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} | ||
