It may be "outdated" in your view. But how often do you see pushrod motors (with flat tappet cams at that) produce 800hp+ n/a. You're right they are solid axle cars. Solid axle and IRS both have their downfalls. The truck are style suspension that is used in cup cars is a very reliable and proven set up, not just in the roundy round world. Only on the slower tracks do they use the fans, and why couldnt something like that be applied for use in a road car? So what other "BS technology" is there?
I'm sure you're one of the many people that hate on drag racing as well. While we're talking about BS stuff. Lets talk drifting, who needs hydraulic hand brakes in a street car? Why use zipties to hold everything on?
I'm not knocking any form of auto racing, I enjoy it all, I really do. I just wish there werent so many close minded people such as yourself.
