usually i am running the 17,20 tooth combo
The 15T is out of question, is too short. I usually go with a 16/49 or 17/50 as the 1st gear. In extreme cases a 16/50 is what you need to get a brutal holeshot from deadstop but this makes the 1st too short and you need to get your 2nd gear to not bog on the shift and like someone said, scream your monkey.

Seriously, the 15T is too short and would not be of advantage, massage your clutch to get the punch you need (a stiffer clutch spring would be interesting).

Yep, the spur gears and pinions could be the same (or almost...) but, what can do lots of difference is the internal reduction of the car. I doubt you can mesh correctly a 15T on a reasonable gearing for your MRX4. But you're free to test (just remember you'll be going with a 1st gear of a little more than 8:1 - Almost tractor puller...).

All depends on what you take as a 'big' track. My track is very flowing, on the link I provide, there's a photo of my track from Google Earth (btw: the cars parked at the right side of the track measure around 4.50 meters long each just to take an idea of the lenght of the backstraight).

A common gearing here is 16/49 and 20/45 or 44, with rear tyres at 73mm.

Just forgot to paste the link:

I think more heat sink & stronger to hold the engine than the stock one

Default one piece

the new one piece motor mount provides better heat dissipation and more rigidity. i have been using it for the last three weekends along with the stiffer chassis.
honestly, not a huge difference, but the car is a little more responsive.
today i actually hydroplaned coming out of turn 9 at our track in hamilton.
what a great day of racing, i love these cars.
