Are these drastic differences felt on the track? I have a hard time thinking anyone would be going through a corner fast enough to tell a difference on the street.
Dave I guess I will give my input on this... Chassis rigidity is always good. It helps every suspension component work more properly. The looser the car or section of car, the greater the benefit. For example, slightly more benefit on some parts with targa cars than coupe cars. More benefit tying together parts of the car where there are "holes" than where there the car is already solid.
Will the average person feel a difference? IMO that is pretty questionable on a street driven NSX. But the more suspension you have, the more wheel and tire you have, the more power you have, and the more speed you have, the more the chassis has to control. So the more bracing helps. If you are running 1000 pound springs it is different than 240 pound springs. If you are taking corners on the track, it is way different than on the street. IMHO, braces sell very well, but few primers buying them actually get use out of them. There are more than one or two braces that plenty of people have bought that IMO are nothing more than a feel-good purchase. There are also a lot of beneficial claims attributed chassis bracing that really just aren't there. So the majority of brace purchases are really for naught, because either the brace is stiffening a spot that needs no stiffening at all, or it's designed poorly where it just flexes too much and adds minimal help, or the rest of the car, driver, and road just aren't to the level where chassis rigidity is a weak link in the chain. I am always skeptical of another brace coming to market, with all the buyers signing up. Sometimes I think they sell just because they are an inexpensive mod. Another thing no one thinks about, is what this bracing does to the car's crash structure and crumple zones. You are at points seriously altering in how the body will behave in an offset crash for example. No one really knows how these will be affected, because none of us have the computers or engineering know-how to know for sure. Aftermarket know-how and factory know-how in this area are vastly different.
Now having said all of this, rather inappropriately on Cody's group buy thread, I will also say this: These things are the real deal. They are well-designed, the best I have seen to date. There is no doubt in my mind they are extremely effective, and if you run on the track with a stiff suspension at high speed, this is a must have and probably very worthwhile. In other words for the guys that want chassis bracing, no need to look further. On another level than anything I've seen from anyone else.
Ross (STMPO) was actually about to produce another bar that was so unique and so good, it would have done wonders. It replaced a major section of the car. I don't want to speak for him but imagine something in the shape of a spider web that tied in at multiple points. Anyway that is nothing but a dream now, his products which were excellent, are no longer being produced. I am really glad to see this stuff from Cody, and will most likely buy a few of them to go with my current STMPO braces.
Cody I hope it is OK I expressed my very honest opinion here. Forgive me if it is out of place. I am very interested in the front bars. Unfortunately I do have that downforce duct for my R hood, but I may change it so I can get your bar. My bigger concern is paint. These are painted and not powdercoated, right? I've seen too many braces and bars start to chip and rust over the years. Looks great day 1, looks like garbage 2 years later. Are you comfortable with the finish on these lasting?
