Durability is fantastic. I was driving like an idiot and caught the rumble strip in the sweeper sending the car cartwheeling the entire span of the track. The car still finished the run and was minorly out of alignment.

Only parts I would recommend for asphalt is the 4.75 springs for the front, KPA really woke up the front end of the car, and a gauge to properly set up stops and droop is key.



what is KPA?

Correct. Its an option part. Little pricey but was well worth it.

Any suggestions for good low friction belts?

Does anyone have a good starting point for really high grip black carpet? I'm probably just going to run 21.5 TC or 25.5 LMH.

Yes, 3x351mm

Belts in the box are more suited for modified racing, if you are running stock I'd get some low friction ones


What makes them better suited for modified racing?

Less likely to skip, more durable

The cheapest ones you can find. I have had a set of the awesomatix ones for years.

I had some from my Yokomo MS1.0 that fit. (BD-351LWA). They are durable, quite cheap (about 25$ for 2 at Banzai Hobby) and are made by Bando.

For those running the MTC3 in Stock, any advice as to the use of the option Mugen tungsten weights (qty & sizes) to get the car to 1320g?

Lots lol
I put a 15 in front and behind the motor plate, then a 10 inline with each of those.
Then a 10 to the left and right of both belts ... in front of the servo and behind the esc/battery
Also stuck a 10 between my rx and fan
Plus I run a 22g SSteel Sortafast battery plate

My idea was to keep them as close to the centerline of the chassis.
I just wish they would lower the weight again, even if it was just 30/40 grams lol

Shock spring?
 
4.75 springs in front ? Progressive 4.75 or regular 4.75 ? For asphalt .

Both! Depending on track conditions and your preference, progressive can make the car easier to drive especially in high grip conditions, linear if you like a little more reactive car. Look what other people run at your track, even different brand cars, the theory still applies.

Thanks for the information, I'll plan accordingly lol
