I didn’t say anything about them not allowing the rear end to plant any harder. As a matter of fact, that’s exactly what they do. That being said, I can't count on both hands the amount of guys I've seen at the track who've changed nothing else, end up with worse 60ft times because of the use of beefed up LCA's alone. Yes, they plant the rear end harder, but that's where the problem lies. A stock radial has a harder compound rubber on the tread face and stiffer side walls that don't buckle or hook anything like a slick, or even a DOT drag radial. When you stomp the rear end like that, it "shocks" the rear tires causing them to break loose that much easier. Lower Control Arms are great for consistency, but without further traction enhancements, your more often than not consistently worse.
You believe what you'd like, but the LCA's on an otherwise stock car do very little to improve strait line acceleration and handling
alone. This misinformation has been running around for years now and instead of questioning it, most people just accept it as gospel because it seems to be the buzz amongst enthusiasts that don’t often know any better. Ask anyone who’s serious about drag racing, or autocross racing and they’ll tell you that running any one part alone, isn’t going to win you any races!
You call it bad advice….I say the only thing worse than bad advice, is a person who consistently walks around with their blinders on and believes everything they hear, just because it sounds like the right answer. Before you criticize, go back and re-read what I posted above and pay attention this time. I didn’t imply a set of LCA’s wouldn’t improve traction or handling at all. I stated that without additional supporting parts, their impact would be minimal. LCA’s alone won’t shave any time at all off of your track time, but combine them with stickier tires, sub frame connectors, autocross or drag friendly shock and spring combinations and then you’ve got a contender.
My suggestion to anyone wanting improve the way their car handles or accelerates would be to purchase all or most of the suspension and/or chassis stiffening components at once and install them together. Or if money is tight, buy them one at a time and wait until you’ve accumulated the necessary combination of parts before installing them for maximum effect. It’s just like adding a set of cams to a stock car. The cams alone although they provide a nice lumpy idle really won’t improve things a whole lot, but combining them with host of intake and exhaust mods and/or a recalibrated EEC will really let you extract their full potential. And in turn provide a much more satisfying feeling afterwards.
Be careful where you’re pointing fingers and what you’re quoting as bad advice….cause the guy who decides to go against the grain may be the one who walks up and down both sides of your car at the track next time you run…..and perhaps with a lot fewer high dollar and possibly unnecessary parts in their car when they do it.
