What things should I get on a hpi rs4 evo 3 for racing?
It already has a Dynamite .15 Mach engine, alunimum rear supension arms, front and rear knuckles, front bulkhead, and a carbon fiber rear shock tower. It also has sway bars.

Is the Mach .15 engine good for racing, is there different classes for different engines? (I only race electrics, so I don't know)

Thanks

Well if ur going to race in roar legal events,. Then u can not use a .15 motor or a 5 port .12. Also having a good set of tires, and driving skills are a must. It's not all about power. Suspension tunning would also help.

I would just race it at my local track and in front of my house. Also would a thunder tiger .21 engine fit in it?

Well check the track to see if they run roar rules since many of them. If so, u would only be able to run in the outlaw class where everything is legal. The .21 would fit IF get wolfpack radicals engine mounting kit.

But remember the more power you have the harder it is to nagviagate around the track .
