Yeh they would have been silly money as they would have been quoted on normal standard springs,which are about £60 quid each easily, not port of entry fitment on the SR like the springs, back box,speedlines and decals that all would have been fitted at time of arrival in the uk, hense the name port of entry. Can get normal standard springs but they wouldn't have been lowering springs 25mm, just normal ones. The part number on the lowering springs starts wit AM11 (cant remember the rest) which is a TTE part number, the number on your bro's estmate will be T5numbers-5numbers (hopefully anyway). Cheers Sam
