Here you go. I installed the esc cap on top of it to get it out of the way.

not really, my car is very underweight and needs 50g to get it up to weight, so I had to put it somewhere.

Think about the length of the 'lever' that is exerting force on the tire with a longer lower arm vs. a shorter lower arm. Same shock position, same spring, but with a shorter lever (inboard mounting location is moved outwards.)

If you really want to feel a huge difference, try going short shocks and short arms...
Full disclosure the purpose of asking how the short arm conversion affects the handling separately is because i use Nitro foam tires 26mmF/30mmR , and i am looking for more front end traction/side bit.

Default Indoor Carpet Question

So I'm a few weeks out from starting to run on the rug, and I had a few questions regarding running on carpet. I've seen alot of people talking about the aluminum chassis on carpet, but to my knowledge there's 4, Yokomo, Excellab, Samix, and Radtec. Has anyone tried more than one on this list and have an idea on which is better for what reason?

I've also heard/read about guys running short arms and short shocks on carpet, is there any advantages to doing so?

FYI, running 17.5 and 13.5, I'm sure it'll make some kind of difference.

Does anyone have the toe chart for the short arm suspension conversion?

Thanks!

Default traction on outdoor asphalt

so other than shorter arms and maybe some ballast weight for low grip outdoor asphalt in winter were the track surface temp is about 10-15deg and no sugar water is used

Rex34's I don't think have a low enough temp rating and literally cool off within 2 mins being on the track.

I have also removed the sway bars

Well my lightly used BD7 '13 chassis is tweaked. On the left rear it's 0.4 mm and right front is 0.2 mm. I'm kinda scratching my head as to why this has occurred. I haven't hit anything hard and I've only broken a front left hub carrier.

I guess it's time for a new chassis plate.

Has anyone swapped out the stock chassis for an aftermarket version?

Samix, Smokem?

Aluminum or carbon fiber ?

Been racing a 13 inside and out for a few years now, still perfect on scales

When you tightened the top deck down did you do it on a flat surface with something like this pushing down on the shock towers ??

http://www.muchmoreracing.net/produc....php?pidx=1094

you don't need anything this fancy, but I always make sure I am pushing down on the shock towers as I tighten it up. If you don't, just the tension on the front belts can cause the chassis to twist.

Edit: I always check this after every run regardless if I hit anything or not, as on the yokomo there is some play in the topdeck holes to allow it to be aligned without any tweak.

evochick - Yes, I do all of the above to untweak my chassis.

How heavy is your car in race trim? I have 30g of ballast to balance out the car and mine is almost 1440g race ready
