Default RS4 3 Evo+ 70+mph?

So i'm going to buy one of these RS4's asap- specifically the BMW M3 body version. How can i boost the speed from 50 to 70mph without over complication and how much would it cost?

Bigger gears and get the O.S. 18 tz motor/ tuned pipe. Should cost under $300

+1 on what ProRacer said. I see you only have 1 post. If you're new to rc, then I would suggest baby steps. 70mph will break more parts than you'd like.

Spur 37/and Pinion 23 all from HPI and yes and OS 18tz woth a good pipe, but seems that HPI is not making spur37 anymore.

I started to use Losi's 19/26 pinion/clutchbell with HPIs 37/43 sours and they mesh correctly.

Look at my vids.

keep looking under my youtube file, theres more speed runs and dragracing
