Hello,
Im building a westfield race car using a 1995 R160 sti diff and shafts, the hub flange I have is 100pcd and I need a larger dia flange to fit a centre lock wheel adapter to. The newer 114.3 pcd flange is the ideal larger diameter but im not sure if the older type R160 shaft splines are compatible with the female splines on the newer type flange? Has any one done this conversion perhaps to fit the newer style wheels on the older model? Any help would be much appreciated as Im tearing my hair out trying to get this sorted Thanks!
