Also i found another problem with LA-59. When i tried to screw in the lower kingpin, the whole knuckle binded and couldnt turn, i did some investigation and found that the upper side of the c hub is 4mm thickness, and the lower is 6mm. At the top side, when i tighthen the kingpin down, it doesnt bind, but at the bottom it does. Do i have to grind off 2mm from the lower side of LA-59? i think this problem also occurs for LA-27 ? If kyosho knew about this problem, why did they still mold them these way, they actually expect their customers to grind it themselves ?
Also , Welshy, you said that assembling LA59 with the inner hole to push out the front, if i didnt do that and used the outer hole (less track) what would the effect be? would the car have less steering or more ?

Firstly king pins. Make sure you use the items that are in the manual otherwise you will have problems. Me I used to loose a lot but then started using thread lock. WHen installing I would suggest doing the bottom first but only tighten up gently until it gets tight, then do the same with the top and then gradually move each a turn until its spot on. I have also used a washer and normal hex screws and is as good but you need to make sure there is zero slop in the washer. Its not the best design and if there is any slop on the UJ the vibration does tend to make the bottom king pin vibrate out so worth thread locking in and checking regularly. Look at the manuals for the ZX and ZXR, ZXRR as on one of the kits, I believe ZXRR they use hex washers that fit flush into the castor blocks and you use a screw to screw into the washers and that way you have a better option if you find zero king pins.
With the wider front end the car is much more stable, and much more forgiving but has much more steering. The standard setting is ok but understeers more and is hard to find a setup that is easy to drive. When I opted for the wider front I went from last in the Welsh Championship the previous year to fifth. The next year I lost the title by one point, but the car was a different animal with a wider front end.
I then several years later tried a fractionally narrower rear end and that gave more control so the rear followed the front and didn't want to bite and grip roll, so made the car more intense into and out of corners so you could use the power more and pull a gap when needed on the infield.
Try the standard car first and make your own mind up, all the info is on here and radiocontrolzone with all my design ideas and what was good and what was not. Hope this is of some use.
