Other questions for the main, are you going to change tires(1/2 hr in a parking lot can be tough on tires), are you going to mix up the shores to compensate for wear, are you going to cut all four tires to different diameters to compensate for wear? Half hour at the Fort I would probabley start out with the left front .5mm larger than the right and the rear left say 1-1.5mm larger same shore. There is "no tire wear at the FORT" so to say, there maybe to much traction though...NOT! there is no such thing as to much grip only to low of a roll center
Thanks Drew.
Are you going to be at the Winter Nats?

Exclamation LONG BELT FIX MAYBE?

MRX5 Long Belt Fix.... MAYBE!!

In my MRX5 manual PAGE -11- Figure 27 Kit Bag - G1, G2

Manual photo suggest you install part #H0294 belt tensioner guide with bump stop(thats the name i give it) at the bottom.
My suggestion is to install it with the bump stop to the top and i find that the belt teeth at its closest is 3mm to 4mm.
I cant tell you that the teeth will not stripe seeing as i have not driven car yet.

My camera battery door is broken so i cant take photo!

Good luck let me know if its works

Yes, thats what I have been doing. Make sure you file the corner of this part which faces the engine mounts so they don't touch.

Default one-piece engine mount

Guys,

Is this a necessary add-on?

If so, does Mugen/MSR make one, or should I go with the Arrowmax brand?

Thanks,
Steve

I crash more than most and have raced the car on a smooth and ruff track and mine has never came off. But if you feel more secure putting one on then I would, personal preference, it's not going to hurt as long as you do not have it too tight. When mine comes off I will, lol.

You really don't need the uni-block(one-piece engine mount). It's an option to help prevent chassis flex in that area of the car. If you decide to purchase one, you should get the MUGEN brand .

IMO, rear arms, frt upper eyelet, frt lower arms, plastic steering knuckle, gears, bumper and clutch parts, not that the clutch is bad, it's just nice to have clutch parts and clutch bearing incase. These are safe parts to have. The out drives are good. The tighter and more turns at a track then they will get sloppy but not quickly. Just because on and off the gas slaps them around pretty hard.

I am sure other racers will some other parts to mention.

Front shock shafts, bodies and plastic shock parts. Not because they are bad or easy to break but because they can break in a hard front wreck and no one seems to have them when you need them. Also a front shock tower.
