As far as track width change, it's not any more of an issue than on a canned ham. They have the same issue thing. As for the fork and retainer.. Both OEM parts are cast alum. We never had an issue with either while testing, and we drive the cars hard. However there are some people that seem to be able to break ball pien hammers. I have seen the same pictures most of you have as well. SInce it is a perceived weak part, people will be looking to replace it even though it probably doesn't need to be unless you're racing.. We've been asked if we had them enough times to determine there was a "want" in the market place. There are peeps that want them, So we are working on making them. As for limit straps .... That's another whole laugher.. They aren't needed by "everyone" like some "video's" would have you believe.. They have their place, and are certainly required in certain applications.. But "everyone" needing them is a stretch. (pun intended). Its a convenient marketing ploy IMHO.
