Everyone was on whatever tires they had, the spec tire for Reedy isn't available until this week. It was my first time on Solaris tires and I was really impressed. The fast lap of the day was laid down with the Solaris tires as well.

I was running a 5.5 there, but my speed control was set to be really mellow. I was running a gear diff up front but didn't pack it enough and it was really loose. Because of that I was having to be really careful not to punch it too much exiting corners. Putting a spool back in for next week and upping the punch setting on my speed control.

Yeah, when we checked it out afterward, his front diff was looser than his rear.

I'm really excited to get out on some asphalt. I've only had the opportunity to run on carpet with our car, and after seeing Randy's around the track I'm pretty excited.

Default Kit Chassis vs. Flex Chassis

Hi all,

So I'm sorta, kinda, possibly considering trying the flex option bottom deck for the VBC. I probably will at some point, not sure when. I noticed that it's 2.25 mm, which is similar to the standard thickness for many other cars out there (Associated TC6.2, Xray T4'14, Yokomo BD7 2014 etc). The VBC kit chassis is 2.5 mm.

What handling differences would be expected if swapping to the thinner bottom deck? Are many people running the thin deck? Is it better overall?

I'm partly asking because I'm on a tight budget, plus it's a big job to change it out. Just want to make sure it's worth the time and money before investing.

Peace,
Sam

I recently got a flex chassis to try outdoors, so we'll see. I honestly don't really know, though, as if you look elsewhere there really seems to be a trend back towards stiffer chassis (aluminum chassis, etc), although that trend doesn't seem to translate to asphalt, necessarily.

For whatever little it is worth, most of the outdoor setups I have seen still use the stock chassis, although there appear to be a couple ones from the beginning of this year using the flex chassis. If you have the money, though, it might be worth trying just to see if it is your 'thing.' What works for one doesn't necessarily work for others.

Probably worth mentioning that those 'few setups' from asphalt earlier this year using the flex chassis all do appear to belong to Surikarn and Hara, though, so that might show it has more merit...?

The flex chassis makes the front end of the car a lot more aggressive. I found mid corner the front will dig in a lot harder and pivot the car on carpet. I almost always run the front steering brace on the car when using the flex chassis.

When the grip is decent on carpet, I always ran the 2.5mm chassis. Timezone Grand Prix had pretty decent grip, and the stock 2.5mm chassis was significantly better for my car. Rolled through the middle of the corner much better without that weird "dig" moment. Slightly higher roll center as well (0.25mm) due to the additional thickness of the chassis.

I have been running the thinner chassis again during club racing since the spec tire we have been forced to run is a little less than ideal. The thinner chassis just made the car feel a little more planted and settled. I feel it will do the same thing on asphalt as well.

I am running the 2.25mm chassis on asphalt and tend to agree that it is aggressive.

My car in its current state really attacks corners and isn't as smooth as it is with the 2.5 chassis, but the car is very fast.

I will be numbing the car a hair because it is both extremely responsive and aggressive.

I really like the 2.25 as it suits my style of driving, and I am able to shed 10 grams.

This past weekend during testing, it was the faster of my two cars and will be my choice for racing this weekend, but your mileage may vary.
