Nice. Haven't even driven the car yet and I already want upgrades. Haha. Thanks Eric.

Welcome aboard! Yeah there are a few minor imperfections with the build as goes to almost all rc model cars but once parts are freed up and glitches sorted its a fantastic handling car. Enjoy

posted this on the facebook arc driver page. spring charts for arc are in kgf/mm and not in lb/in like everybody else.
here are the rates

hardest to softest
kfg/mm to lb/in

red/.36=20.159
white/.33=18.479
yellow/.30=16.799 (kit front)
green/.28=15.679
blue/.26=14.559 (kit rear)

I hear some have gone to the hpi silver rated at 16.9 according to rsd's spring chart true rating of a 15.9. so it falls between the yellow and the green springs. i hope this helps.

Word of caution on the spring rates. They vary from spring to spring within the same manufacturer and also perform different on it's compression path. This is why RSD tested 5 different springs and took an average. So matching a 16.9 spring to a different manufacturers 16.9 spring can have completely different results. I think the reason people favor the HPI silvers on asphalt is the way they feel during compression. They are a pretty consistent spring. Finding them right now is tough, don't know if they've quit making them or just haven't made them in a while, but they are out of stock just about everywhere. The ARC greens front and rear feel really similar, just a little different during compression. I was using greens front and rear on the first day I used the car and they felt really good. I'd go with either at this point.

No problem Tony. Glad to hear your car is almost ready for racing. Be sure to let me know how it goes.

BTW, looks like we will have 1 or 2 more Black Editions and that's it. We're also working hard on the back end of the site to add ARC parts and they will all be uploaded at once when complete.

All those times I was looking over your car I ended up getting sold on it, lol.

Really though it looked like a very well put together kit, then Lemar showed me the black edition and it was game over. Always been a fan of stealth!

Default Aluminum chassis for Carpet?

Thought I'd throw it out here, running a 2013 ARC currently but have an upgrade kit on order. Has anybody run the optional aluminum chassis on carpet? What have your impressions been over the stock carbon fibre chassis?

My car was really hooked up last year and very consistent on an open mid level grip ozite track. Occasionally the car would grip roll (chicanes or quicker transitioning areas), had some difficulty tuning it out of the car. Wondering if the longer shocks, hard set of arms and 8.5mm steering rack might help.
