[quote][i]Originally posted by Kyle T[/i] [quote][i]Originally posted by Ste[/i] What are the rivnuts for? you know they're really not structural and only good for holding a panel on that doesn't come under much stress [/quote] The OEM toe links are single shear with a very long bolt which anchors both the toe links and the trailing end of the lower wishbones - and they often fail. There are 2 options on the market for upgrade kits split across 8 or so manufacturers: 1) Brace added between the two inboard links, brace in effect puts the links into double shear 2) Brackets added to the subframe to put the inboard links into double sheer. The brackets are held onto the subframe with 4x M6 bolts via the rivnuts. They're only torques to 10nm and aren't really intended to take any load as the brackets slot into contours in the subframe anyway - and the force is transferred efficiently onto the subframe. The preferred option is 2) as the first option is transferring load into the "other" toe-link rather than the subframe itself. It's a known solution and most track/race Elise/Exige/VX cars have had this upgrade and is still being performed on new cars from Lotus. The main downside to this is that the OEM toe-links are a sacrificial component in a shunt, so if I slide into a curb or whatever the subframe will be taking the smack and there are known cases of subframe damage with upgrade toe-links despite the rivnut/M6 fastenings.
