OK, I had to bite on this one, as it is a pet peeve of mine. Keep in mind I'm 35, and grew up modding/racing V8/RWD machines.....
The newer import/compact car magazines that are out there really aren't all that great at doing what they do. SCC, Super Street, and Turbo included. IMHO. Just take a look at any 'old school' magazine (Hot Rod, Car Craft, etc.) and tell me which one does a better job of actually showing you things to do to your car, and what effect those mods ACTUALLY have on a car like yours.
IMHO (again) SCC and Super Street are close to worthless, as they feature cars with this mod and that one, but yet they don't do any testing at all to see how much the car is improved over stock. No acceleration figures, braking, etc.
How much is a G-Tech nowadays???
Now....flip over to a magazine like Car and Driver, and you'll see a car magazine that is done the way it should be done. Granted, C/D covers new cars, but yet they also dabble in modded cars from all over the automotive spectrum.
AND, they actually test the cars and tell us what works, what doesn't, and why.
Sorry to ramble, but this is a major concern of mine. So many people who are new to 'hot rodding' (generic term) are buying these magazines, and realizing that just plopping parts on a car is all it takes to get in one of these magazines. Forget the actual results of modding your car....just buy the parts and we'll put you in here, too!
SuperStreet is the worst, by far, of a less-than-stellar lot, if you ask me. No substance whatsoever, no reason to read it. I keep thinking I'll write the NIRA folks and tell them to keep the magazine they keep sending me as part of NIRA membership. Some day...
I've rambled enough. Sorry to waste the bandwidth.
