Maybe I need to clarify my above post. I think GTPlanet is the best freely available hardware forum on the web. And on subjects where there's a lot of owners, it's the best racing resource on the web (free or not). I'm just saying forums by their nature all have an element of cult to them. If we're being honest with ourselves. Iracing (hardware), however, is excellent if you're looking for modding details for hardware that's not prominently owned here.
You also have Berney from Simexperience posting there. Although I'm not sure I can truly give iracing credit for that, because Berney walked away from GTPlanet because one person got under his skin? That doesn't speak very well of Berney TBH. Or what kind of support you can expect from Simexperience if something goes wrong with your purchase. I view that type of volatility as a red flag personally.
