Most FWD cars are a less-than-desirable platform and are usually only competitive in racing when they’re against similar cars in the class. That’s the reason there is classing. It’s just physics. RWD cars are much easier to rotate as needed. It’s not a bandwagon, and it also came from someone who tried to do this previously with his Saturn ION Redline (Cobalt SS) and he cherished that car like it was touched by God himself. I wouldn’t say most of us are underdogs, as most of us don’t enjoy wasting money to be “the first guy doing it” or because it may work on paper, but not on pavement.
I’ve been in the same situation before… I was trying to turn it into something it’s not, and between the lack of aftermarket support and a not-so-great platform for tracking, I gave up on it and went with what works well. Ideally, a person wouldn’t drop a cent into their cars until they learn how to drive it (myself included), but we can’t usually fight that urge. My LGT had more money into it than my M3, and I can promise I’m at least 6 seconds faster at just LRP on the same exact tires (although different widths). There comes a point of diminishing returns in modifying cars, meaning when you go so far, that you need a lot more money, power, etc… to do the same thing you did when the car was stock. To me, a person who has been tracking for several years and have progressed very quickly among the classes of driving, I’d recommend a different platform for this guy if he wants to do anything more than maybe sway bars and lowering springs, because unless the guy is investing money into his driving skills, the Cobalt will definitely be slower and worse “handling” than any stock M3 with the same driver.
The OP said himself that he wants a “racing suspension” and that “money is no object”, so I am giving my best educated opinion on the subject matter.
