I can imagine the underbody components would serve a similar (though less effective) purpose as a bolt-in cage. You're connecting fewer point but it's a reinforcement solution. I've always questioned the internal mid-brace as its doesn't seem like it'd fasten into much of anything structural, but if you're going to track your car the exterior bits can't hurt. Haven't done my homework on this companys products, but if they're made right chromoly tubing is very strong and the same material used in cages/tube chassis. I'd be willing to give it a shot.



I recall a big flame war back in the RDT days where people doubted that the Weapon-R engine damper would reduce torque steer, but supposedly it did.

These things tend to be made for a reason, but the biggest factor is whether they're made properly.

 

Yeah it might be the same material as a roll cage, but it's being used really poorly. Metal is strongest in tension and not bad in compression. Putting bending loads on a long piece of steel is a bad idea, that bar is increasing weight and cost for negligble benefit.



That's assuming that the boots fit perfectly and the thing has to be hammered into place. If there's even half a mm tolerance in any of those, the bolts will simply move around inside their cutouts.



There are very few vehicles on the planet where this could be considered the best way to improve the car.
