Scott: yes, the rear hinge pin came all the way through the insert and cracked the front holder and was starting to come throught he rear bulkhead. It stopped at the screw holding it down. Somebody also needs to build an aluminum rear front insert holder along with those brass inserts.

i like your style chook your a quick driver AND you like your bling!

ATTENTION AUSTRALIAN MTX4 DRIVERS:

i noticed with my australian kit (purchased from ozzy shop) the tyres were the old style mtx3 rims and the compounds seem to be 42 fronts and 40 rears. a friend who purchased OS got a new rim design and very soft foamies.

also, my mates brake disk pads are blue, and mine are grey.

did any other ozzy drivers find this, or have different tyres to mine? my box was alos not factory sealed, but my mates OS purchased one was.

overall, i haven't finished building it, but was pritty suprised at the front baulkhead missmatch, this isn't like mugen at all , as well i heard initial kits came with two belts for the side, and later, this was changed. i think mugen should have included both belts

Just started the build last night but i managed to do the front suspension only, will continue it tonight. Thanks..
Use Tamiya Grease to turn the pillow ( pivot ) ball easier.

I'm using MTX3 titanium, and could penetrate even deeper than in the photo.

Use Hudy Setup Tools to measure front width ( 199 mm ) and front camber.

i got mine from barry walker. without tires

my brake pads are grey and i only got one side belt and my box wasnt sealed

whats the problem with the bulkheads? mine went together perfect and everything fits 100% besides from the motor.anyone else find that you have to take off the belt tensioner to get the motor in?

I have to take the tensioner off also. Kinda annoying but oh well. I didnt have any probs with the front bulkheads.

Scott, What do you guys true tires to start at in Vegas these days? I think I was cutting to 63 last time I was there. Dont really remember since it was like 8 months ago. At Revs I was cutting to 58.5 and 60.5. Is a 45-42 going to be the hot ticket at Crystal?

the official word is the 1st batch of faulty front bulkheads will be replaced with the correct fitting ones, you will receive them from your place of purchase so keep in contact with your supplier for more news.the kit comes standard with grey pads the blue pads are an option part,the side belt in the kit is the 1 and only belt available at present and the new 1 degree offset wheels are not yet available from grp fast tires and yes the bling is a must

Hi Guys,

Been doing my MTX4 build now and i am wondering why the front belt is a bit loose not like the rear, as the manual says, i should use the 5mm for the front and the 6mm for the rear, what pulley should i use for the front belt assembly and the rear and the side belt as well, also, my kit comes with only 1 side belt and its very loose after i installed it, its so loose that when you pinch the belt in the middle, the inside would almost touch each other (as shown in the pic), im afraid that if i install the belt tensioner, it would be so low that i would not have any more adjustments after the first run-in. Does any of your kit also comes with 1 side belt or you did purchase a shorter one.

Thanks.

My kit (US spec) comes with 2 side belts, one fiber and one rubber(recommanded for use from the updated page), both belts are about the same length. And if you feel the front belt is too loose you can always adjust the eccenters.

Front Belt and Rear Belt : Try to readjust the position of eccentric bulkheads. Read ther manual for direction to make it tighter or looser.

Middle Belt : We get 2 middle belts. My MTX4 friend use the fiber ( shorter ) and I'm using the rubber belt ( longer ), and you adjust the belt tensioner quite low ( low cg ).

My side belt difference from yours, it made of rubber and shorter. Are you using the standard position of the front and rear belt tension? and from the photo, the gears seems wrong

Scott, What do you guys true tires to start at in Vegas these days? I think I was cutting to 63 last time I was there. Dont really remember since it was like 8 months ago. At Revs I was cutting to 58.5 and 60.5. Is a 45-42 going to be the hot ticket at Crystal?

I was starting today at 61.5 rear, 59.6 front. Kawahara 37's. By the time I was done today my car was really good. At revelation I was running 58 rears and 56 fronts Fast 42's. One thing with this new car is I am finding if you run your tires above 61mm in the rear that the only way to get the ride height below 4.5mm is to use front springs on the rear. The biggest tires I ever ran here were 62 rears 61 fronts on my MTX3. If I put 62's on the back of my MTX4 my ride height will be too tall. I have never been to Crystal Park, but Mike told me probably 40's or 42's. He said maybe 45's, but probably 40's or 42's.

On the side belts. The rubber side belt does seem a bit loose, but it does not seem to be a problem. I was able to get the shorter belt on, but I won't need much of a belt tensioner with that belt.

you mean the pulleys? can you tell me how many teeth pulley should go to what side and what shaft...im confused, this is my first build of the 4 and the manual is not as clear as to what number of pulley should go to this specific shaft...i saw some pics in the mugen website and it seems that for middle shaft, the side belt pulley is larger than the main shaft side belt pulley (outer one) and still i can see minimal slack in the belt, not so loose...
