Hi, bigH's springs are from OZ they are King Springs and rated at 490lb/in mine are OME aslo from OZ and they are 420lb/in but I have 2 sets at the rear. If you are double dampering then you probably don't need the Koni heavy track raid, 8 of them would require another mortgage anyway. If you have raised your height get the +2" dampers. The wheels we both have are from OZ too. Did I mention I don't like spacers You can get wheels that will give you a better offset this is the way I would go. I liked my wolf wheels but changing them saved me 5kg per wheel and I have 7. this isn't why I changed them just an additional benefit. If you are going to use spacers anyway then steel will be better although they are very heavy QT services do steel ones and they are a Quality company. There was an American on one of the Rover forums I frequent who had just bought some performance 8x16 TX alloys and I think he paid $200US each. I would stick with the 130 axle as at the very least you have stronger CV not sure about the rest but you could always weld some brackets to the axle. bigH's rapier is a '89 model and it is probably a little higher than yours, he will probably chime in and give you the exact measurement though.
