Lc90 sa cant be swapped as the lc100 is far wider. If they are coming in your budget buy them and do the solid axle swap after a year or two when you really feel that a solid acle would be better. Till then do the rest of the upgrades and enjoy the ride. Solid acle is only better than ifs if you have 36inch tires and 5-6inches of lift. Otherwise the benefit is negligible
