A Main does stock Motonica parts. RS2 update provides more tuning options for the P81 platform.
The RS2 front tower and lower shock mounts essentially move the shocks further out, both on the tower and on the arm. I have tried this setup and on our track I could not tell much of a difference.
The RS2 front knuckles allow for ackerman adjustment and for king pin inclination (KPI) angle adjustment. They also allow for the axles to be moved up, down, forward, rearward, or centered, just like the old knuckles did, and they also allow the axles and bearings to be removed without removing any other parts. The ackerman adjusment allows the steering tie rod end to be moved in/out, forward/rearward. You can alter the steering feel and reaction with this adjustment. The KPI adjustment can be done in 0.4mm to go from '+1.2mm' to '-1.2mm' angle adjustment. This has a similar effect as changing caster as it changes the contact patch of the tire as it rotates and it also changes the way the car rolls in the corners. With the old knuckles some drivers would run them flipped (myself included) so the new knuckles allow this to be done without any mods and to be done in any 0.4mm increment in between. There is no better or worse with this, it changes the feel of the car more than anything, but it is one more adjustment you can make to either suit the way you like the car to drive or to suit the track conditions.
Finally, the rear upper arms are replaced with camber links. This allows slightly more flex in the rear suspension, and in theory at least, should provide more rear grip.

Andy, sure no problem, but A Main does have the RS2 upgrade kit on order and will have it back in stock very soon. I forgot to mention the RS2 upgrade kit also includes the adjustable blade rear sway bar.

I must agree with you Garen. The handling of my P81 is superb since I had the RS2 upgrade.

Default optional parts

just wondering if it's possible to use the mugen's new light weight axles in the front and rear and also if any other brands belts can be used instead of the motonica belts.

thanks
andrew

Andy,
I've been using the Mugen Lightweight axles (F/R) on both the Nitro P81RS2 as well as the electron version. They've worked out pretty well, and are surprisingly robust

But to convert to these axles, a few other Mugen parts must also be used as well:

Mugen Front Inner drive cups
Mugen Universal Joint axles (Front and Rear)
Mugen Wheel changing lever kit (Front and Rear, including the Roller pins )

HTH,

cheers,
-m

Go with the Arrowmax parts for the MRX5. They are cheap and last forever. Don't try the titanium axles though.

Also, you don't need the wheel changing levers from Mogen, the Motonica ones work just fine.
