RobSheffield Posted July 13, 2009 Share Posted July 13, 2009 Is there a reason these have not been developed yet? The reduction in both unsprung weight and overall vehicle weight would be fairly significant. Grant Ikeya arms are available, but i was thinking along the lines of oem shaped, none rose jointed arms and lighter alloy hubs. Link to comment Share on other sites More sharing options...

Chris Wilson Posted July 13, 2009 Share Posted July 13, 2009 Forging rear hubs and machining them will be *extremely* expensive. Many suspension bits are already alloy though. The forged steel lower arms are made for strength, an alloy equivalent probably wouldn't be a great deal lighter, if made to be as strong and impact resilient. The GTR Skylines had alloy rear hubs, the GTS-t ones have steel. I converted my car, but it was far from simple. No Supra MKIV had alloy bottom arms. Unless your rims and tyres are as light as possible I wouldn't worry about the arms and hubs! Link to comment Share on other sites More sharing options...
