i don't care, i'm talkin to bpt323 who is probably just BSing to sell em.
With respect, can you explain exactly what you mean when you say, "the polyurethane control rod bushing can't even compare to Nyloil ones." Now, the OEM bushings are apparently designed to damp some of the vibration between transmission and shifter and so therefore are made of rubber to accomplish this end. One consequence of this material choice is that it introduces a certain amount of play or sloppiness into the shifter action.
The replacement Kartboy stabilizer rod bushing is made of polyurethane that, unlike rubber, has no built-in 'give' or flexibility that serves a vibration-damping function. As a consequence, the shifter and the transmission are much more rigidly coupled together eliminating a considerable amount of looseness and wasted motion and making shifts feel more precise. According to Kartboy's installation instructions, lubrication of the outer surface of the bushings is unnecessary-only the metal sleeve and mounting stud need be lubricated, probably to prevent corrosion and seizing of the metal parts. In other words, a self-lubricating bushing is not required.
My question then is, what makes the Nyloil bushing so superior to the polyurethane one? As already indicated, the fact that the Nyloil bushing is self-lubricating can't be a factor. What characteristic(s) of nylon would make it more suitable in this application than polyurethane? I'd really like to know because if it can be demonstrated that the nylon bushing will increase the coupling rigidity over that of polyurethane, I'll make the switch myself.
I think it's great that Maz1.8T is making this product and giving us a competitive choice. If his product is at least the equal of Kartboys, that's good news. However, if it turns out that Maz1.8T's bushing is the superior one, that's even better news for us all.

The story of the nyloil kartboy bushings is simple. The material was first choosen for the bronzoil bushings. Someone expressed the need for bushings that have all the same benefits less the corrosion factor. I had the real bronzoils way before I started to make my bushings. They were great but they did indeed corrode a little after some time. SOOO, I found the next best material I thought would do the job well and Nyloil came out.
NOW, someone also said, why don't you make the kartboys also? I thought yeah why not! Since I already used Nyloil for my other bushings, I thought I could make the kartboys also in Nyloil... it's only cause the tooling was already setup for nyloil and only cause I could just order the same bulk material and make both kind of bushings out of the same stock. There are no reasons why the Kartboy should be self-lubed, you nailed it. It was just to easy my production. And the fact that Nyloil is harder than Poly, I thought I could maybe approach some diffrerent customers.
The fact that bpt323 thinks they are the best is only a matter of tastes. I won't hide the fact that out of the 50-60 sets I sold before, 2 people removed my nyloil kartboys cause they thought they were 'too much'. But that's a matter of tastes... Note that Nyloil is harder than polyurethane... poly is more like hard rubber, Nyloil is more like plastic.
...my mother will like stock rubber bushings, some will say polyurethane gets 'em the feeling they want and some like it even more harder and use my bushings. THERE ARE NO BAD BUSHINGS. GET THAT???
Either way I still want a pair of the smaller ones and I could probably sell a few bazillion of these on all of the mazda forums I go on, all depends on 1.8Ts ability to produce like 100 sets lol
