I have played around with stock 5+1 and aftermarket 4+4, and 4+3 and also running those with 2" wheel spacers. No doubt a slightly positive srub is desired on these cars. For sure you can notice the negative side effects with the wider offset wheels. In a race car situation I would agree that one should try to get as close to ideal as possible. Driving under hard race conditions for hundreds of miles adds up quick both in fatigue, feedback, and parts wear. But the majority of riders/drivers are not racing. The vast majority are recreation drivers that simply want to be pretend to be pro. Many read these articles and preach it as gospel in an attempt to seem intelligent on a subject but have no real world experience to back it up. It is my personal opinion that there are very few drivers out there that can go from a 4+3 to a 5+2 and notice a difference. And if you could, after 15 minuets you would be used to the difference. If you had the option, then yes go with the 5+2 over 4+3. What the ST article says is not false and anything you can do to help the driving experience is a good thing to do. But the truth is the aftermarket is full of 4+3 whereas 5+2 is much harder to find. For the everyday recreation user a 4+3 is just fine. Its not like running this offset will cause an immediate violent crash or cause your front end to fall off lol. As far as the added parts wear meh okay, more wear but how much more? A part that has a service life of 500 miles is shortened how much? 5%? 10% (I honestly don't know) but doubt it to be significantly different. (from 4+3 to 5+2). Just my opinion
