Depends on what you want out of your engine. What size track do you run? Usually the larger the track the bigger the manifold, I am told

What are the advantages of the flat front upper arms on the MRX4R? I have a heap of the old arms from my MRX4 that i want to use but im not sure what the negatives will be.

Also anyone have any tips for getting maximum braking capability with the MRX4R? I have th option pads on the standard disc but they seem to lose braking after a few laps of my local track.

Thanks

Steer clear of the C6. Your $400 would be better spent on gumballs.

The flatarms clear the newer bodies like the Whip and Parma R10.

Use one yellow and one black pad on the brakes.

Is the motor that bad? How about the Xenon .21s? I figured I'd be better off with a new Piston/sleeve/conrod set for under $200 that will fit my Nova TOP and make the motor overall faster than the previous setup. I may also pickup a Carlsen Mod ZX21 from a friend for cheap...barely used. The plan is to run both touring and 8th this year, but mainly work on Sedan.
