here's where I would be super cautious about purchasing direct from KW for several reasons:
1) there is no picture so there's no way of knowing what the similarities and differences might be between this and the Mountain Pass Performance Kit. It could have no differences, trivial differences or big differences. If it's the latter, then they're all kinds of questions about whether they've improved the kit or perhaps 'deproved' it. The latter of course is unlikely but you just don't know. At the very least it won't have the front strut top column and probably will just have the helper springs. You'll have to decide based on virtually no systematic surveys whether the top column is better than the helper springs. But that was an MPP designed part and most certainly is not in the KW kit.
2) it's significantly more money
3) if you have a problem you're dealing with KW vs. MPP. That's no contest. KW is like the Department of Defense, while MPP time and time again has proven their integrity and commitment to the Tesla community. KW on the other hand is probably a technically high-quality outfit but committed to their bottom line.
4) most critically, we don't know whether or not KW signed a non-compete Clause with MPP. If they did, they are violating it. Plus we have to believe that MPP did most of the development work around building a spec list rather than KW. I believe in rewarding people who do the grunt work. In any case it's possible that KW did not promise to non-compete, but only MPP can clarify that. If they are violating a non-compete clause, that's really deplorable and would be a final and excellent reason not to buy from them. But again we don't know. They wouldn't be the first outfit to do an end-run around that kind of agreement. Even if they didn't sign a non-compete clause, funneling kits into their stock pipeline takes them out of MPP stock which MPP says has been almost impossible to create. So even best case scenario, it's sketchy from the standpoint of KW business practice as it says that they are willing to short a developer / distributor in order to sell their own kits.
For all these reasons, I'd suggest a lot of caution about buying direct from KW. I would strongly encourage people to support MPP because they are supporting us.
