READ THIS THREAD if you really want this mod....I know, it is long, but you need to know this stuff!!!!!
Everyone, This is a mod that I developed, manufactured, tested, and installed on my car in 1999. The car was lowered 2 inches, and used primarily as a track car. The ability to adjust the camber back away from the 2.3-2.5 degrees of negative camber was sugnificant in tire wear reduction. Setting the camber to negative 1.5-1.8 degrees, depending on capable suspension interaction (what suspension one is running), the car handled perfectly, and became known as one of the best set up NSXes around. BTW, I put about 10K track miles on my car since then, and the mod is still holding up!
MJ and I discussed having these made, and sellgin them, but......
The down side number one......I had HUGE interest from the NSX community on mass production of the mod, with people offering to fly me across the country to do it for them.....WHY FLY ME THERE you ask, well, because the mod requires that one expand the channel where the camber dial sets in the lower A-arm of the suspension (thus allowing the replacment of the camber dial with a dial of larger diameter, thus providing a greater range of motion). This can be done with a dremel, if you got balls, a steady hand, and money to buy a new one if you slip, or it can be done by taking the lower A-arm off the car and machining it on a mill machine.
Bringing us to down side number two.....the lower A-arm connects at the top of the "A" to the outer suspension member via a "FRICTION FIT JOINT"!! What does that mean?? Well, it means that the joint is fulcrum shaped (a cylinder that is bigger at one end than the other). But two mated members together, run a both through them, tighten them, and whalay, a friction joint. Now this particular friction joint is sleaved, meaning the lower A-arm has a metalic sleave pressure fitting to it's inner joint sleave. When breaking loose the frition joint, this sleave, more often than not, tears free from the part is should stay connected too. At this point, Honda mechanics (everyone i spoke with in 1999) says, it is time to replace the lower A-arm. Big money! Therefore, no ability to have a core charge system where people receive a kit, install it, then send the old one too the supplier to be modified for the next kit. All kits must have 2 new lower A-arms. Very kostly!
OK, so in closing, why did this never become a kit revolutionising the lowered NSX back in the late 90's.....cost, safety, and DIY ease of installation.
I hope the kit developer can put the worries to rest, and tell us exactly how they plan to revise the camber cams lowering ability without increasing the lob size of the cam, thus requiring a modified lower A-arm. If so, I will be impressed, shut my mouth, and return to the babe watching here in Scandinavia, which already takes up so much of my time. Otherwise, I can post pics to help understand more the text above. As if you want the!
BTW, one must produce the new cam dials/lobes from metal that does not cathodically interact with the suspension metalurgy....to prevent corrosion. I made mine form an exotic material called Hastalloy-20, but there are many less expensive materials that would also work, but are very hard, and hard to machine. Ok, back to my cave.....c ya!
I have a Swiss guy here who will have his own kit in a few weeks I think.
