Additionally unless the front springs are kept on the weak side the front looks up in the air. Actually we have run these closed cars in France carrying the spare wheel at the back and having 1100 lbs. springs without running into any trouble. Naturally with both spare wheels carried at the side, the front spring lbs. will have to go up by about 80. HS{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
