The 5, 5.5 blocks raise the roll center and will "loosen" up the rear. I set tweak at the start of the day, before the main and pay attention to adjustments in between.

I am trying to install a mrx-4x clutch to a 35plus21 LC and seems like the clutch screw it too short and I cant get no end play with zero shims

Any help would be apprecaited

Few things to check, assuming you have pulled the shaft and in the same time push the copper collar in so as to ensure no freeplay, then put on the flywheel
1. there should be no shim in between the bearing and the copper collar(come with the engine)
2. if no shim was put, then you may see if the copper collar is too long(compared with any you have)

Hope it works!

Done that.
I even put on the smaller optional collet that comes with the engine.
Im stumped, as I said I am no noob and this has got me baffled

is your engine brand new? there may be some different scenario

if your engine had changed a new set of bearing, make sure the front smaller one(607Z) is inside the casing completely.

Pick a shorter collet.

see if both bearing inside the endbell are completely in(this seldom happens in mugen parts)

What is the overall length of the crank shaft from the engine case? You must be dealing with a seating issue of some kind, in the case or in the bell.

If I remember right, Mugen used to have a shorter collar (the piece the thrust bearing rides on) for some other car. Maybe you somehow got a wrong one.

Gear ratio/roll out?I was looking at the this sheet that came with my kit and I understand that a larger clutch bell decreases top speed and gives better accelaration as the chart shows but what i don't understand is the numbers on the left side of the page?I was guessing they were tire diameter but that didn't make sense to me because a larger tire should give a higher top speed correct?If it is tire diameter then the chart is saying that top speed should increase as the tires wear becasue the gear ratio number drops with the smaller diameter.I am confused.

You are backward. A larger pinion (clutch bell) gives more top speed/less torque. Smaller gives more torque/less top speed. It's the same with tire size.

Also, gear ratio does not change with tire size. Gear ratio is a factor of spurs, pinions and internal drive ratio ONLY. Tire size changes roll out. Roll out is the distance the car will move per engine rotation. Therefore, less roll out means less top speed (the car will travel a smaller distance for each rotation of the motor) but have more torque at the wheels for faster acceleration.

First gear on the shift nob in a real car is the lowest number on the knob.
However first gear in the transmission has the highest numerical ratio.
The roll-out sheet is speaking numerically.

Sohlman, Where do i get the pads the teflon yellows or the black?.

The yellow ones come with the kit. The black ones are the ones that originally came with the MRX-3. I believe they are still available as an option.
