Did you get a new set of rollpins with the arms?

As you obviously can no longer screw the pins into the arms (as you can with the stockers or RPMs) you should have been given a pack of new pins which will probably be held in place with circlips. Other than that they should mount up exactly the same.

Out of interest why did you go with aluminium arms?

I got the pins, its just at the end of the arms they are diffrent as in they have a hole on the top of the arm(not sure for what) and now that iv put the wheels on i have huge toe in so im not sure if thats normal when upgrading to these arms. I use alum arms and parts on most of my cars as i find them alot stronger then stock items and plus makes the truck look tuff

The holes are probably intended for you to use grub screws to retain the pins. Toe-in would suggest the arms are shorter than stockers, but you should be able to counteract most of that by shortening the turnbuckles...

Good luck with the alum arms, i just hope that a big crash doesn't pass the stress onto other parts which will be harder to switch out...

Got a pic?

aha i see ya problem, the turnbuckles are meant to be mounted on the lower side of the knuckles and steering bellcrank, if u install them on the top it will put huge toe in on the wheels. Mount them on the lower sides and u will be fine

Also u adjust the turnbuckles by turing the shaft, the shaft is threaded into the turbnuckle ends, and when u twist the shaft it threads in and out of the turnbuckles, thats what the squared of area is for in the middle of the turnbuckle.

hi i had very similar arms on my mta4 . i think the holes you are asking about are the ones on the end of the arm next to the pillow balls? they are threaded to clamp the arm tighter on the pillow ball thread to stop it undoing itself when your running . i still had problems with mine undoing so i put some nuts on the pillow balls and locked them up to the end of the arm .

I would like to know also .

The MGT/MTA4 has a dual pickup fuel tank that will allow the truck to run when turned over .

Be careful landing jumps wiith those alloy arms , they will transfer impact energy too the diff cases and will rip the lower hindge pin out of the mount . (been there done that)

the later MGTs had the duel pickup removed, if u look inside the tank u will only see the lower brass pickup, they removed the 2nd pickup as it degraded and caused horrible airleaks which played havoc on your tune
