My tyres on the exhaust side are knackered, excessive wear on inside edge on both front and rear where the tyres on the other side seem fine, they are showing signs of wear but nothing like the ones on the other side

ntc3freak

is it rubbing the exhaust?

wayne

hrm didnt think this was possible, but after reading this I checked, and it is most definetely not rubbing the exhaust

ntc3freak

hmmm.look back at ur car n see what is suspicious.

Do the rubber tires or foam tires have the problem? If the problem happens on rubber tires, it could be the inserts. For foam tires, perhaps your tires are too soft (track traction too high for the foam tire you chose). The tire problem may manifest on the exhaust side of the car due to more clockwise turn of the track.

Since your car does not track straight, the problem can be caused by the chassis setup, different tires used and the steering trim. Make sure on the left and right side, the droops are the same, the shock pistons, springs are the same, shock rebound degrees are close, the ride height are the same, same tires. Of course when the steering is at neutral, both front tires have the same toe in/out. Also, check the pivot balls whether they are bent.

i really can't check the toe,droop or ride height.must get a setup set real soon i think it is the shocks.it is hard to rebuild.how do u rebuild bladder shocks?i am not using ae shocks at the moment.

How much camber did you run? I'm trying to guess, your track should have more left handers than right handers? In that case, your right tires' camber are set just right, try setting your car with a slightly more camber for the left front and rear tires, as in less negative....the tires less tilted in. That's the more accurate way of setting up camber, it's all about tires contact patch. A more "negative" camber on the left side of the car will suit a track with more right handers, and vice versa. Gosh...I hope I made myself clear and not confuse anyone here...

There are few factors contributing to the stated problem. Excessive tire wear on one side of the car due to camber set wrongly, front toe, droop, "unbalanced" shocks...
It's very hard to get your front toe set right with the gauge provided by AE, get a setup system will set things straight.

hey tommi,nam lee got one ar ofr sell(new one)?i want the hudy system u see on my signature(that is my wish list )n how much he sells it for?i don't knoe his number

If the car isnt tracking straight check the trim on the steering, perhaps its shifted from the previous setting if the car was tracking straight prior to this problem occuring.
Another factor that can cause the NTC3`s steering to have a mind of its own, is occasionally, the bolt that holds the swing rack to the swing rack arm works loose......if this is the case its easily fixed by tightening the bolt through the hole in the bottom of the chassis.
Also, do a quick check to make sure you havent lost any caster clips.

hey,i think it is the steering rack.one of the screw that tightened it seems stripped.btw,anyone have upgraded to ball bearings for the steering rack?

OK the butchered tyres were rubbers, (stock rtr + to be precise) and the toe on the rear was standard 2 degrees toe in and 2 degrees negative camber.

I tried on more than one occasion to get it to track straight setting the trim, this seemed to work temporarily...

on the front I am running 2 degrees negative camber and I *think* about 1 degree toe out, this said :

I checked the screw thru the chassis from underneath, (the one on the spring) and I tightened it, only a little bit, then discovered my drivetrain was binding and after a minute or two I put it together and realised the screw is touching/binding the front input shaft, so I loosened it back off so my drivetrain was "free" I then proceeded to check for the "missing" caster clips, and they are all in place and are secure, I then for some unknown reason tried to turn the front wheels with my hands (as in left to right ) and discovered that the whole deal looks to be loose on the swing rack mounting posts, with the whole deal moving sorta up and across pivoting on these posts, I am assuming that some slop here could be normal, so I am asking those who know more than I before I disassemble it, also if the person who answers this thinks disassembly is warranted any shortcuts would be appreciated

If the steering rack has more than a couple of millimetres play in any direction it , pull it apart and check everything. A little slop is normal but it sounds like the locknuts top of the pivot posts may be loose.
Undo the bottom four diff housing screws, side braces, shocks, top arms and bumper brace and pull the whole front gearbox assy out you should be able to get to it.
As for the tyre issue, I would say the inserts in the tyres are too soft. Find out what tyres and inserts the local hotshots are using and buy a set before messing with the settings too much.
