Love this car, was able to TQ 13.5 open with a 17.5 boosted, messed up my start, and got back up to 2nd I couldn't put a run together in 17.5 blinky and ended up in the B, but the car was there, only changed tires all day! I'm going to try out mid motor, the indoor season is pretty much done, can't hurt to try it now.

How much boost do you run? And do you change your gearing?

Since I was double running the car, I just guessed, I have an SXX TC spec, put it on boost profile 7 and dropped 3 teeth, felt pretty good.

I don't feel that the 521-1 are faster than the RB6 arms...maybe they feel easier to drive, but slower on the clock for the most part.

Try the whole setup and let me know what you guys think. Adjust ballstud washers accordingly to your tire and grip level. Rear shock length is off the top of my head, but basically all the way up with the longest shock bottom.

Feel free to ask questions if you have em.

good job on the setup Thomas. lots of corner speed, great traction all around, very easy to drive!

Are the plastic rear wide suspension hangers available without buying a transmission case for rear motor configuration? Thanks.

Anyone running blinky MM on outdoor hardpack low bite/loose?
Thinking about trying it on wet hardpack w/ loose top... Maybe a bad idea?
