Tuning Note: We have found that adding screws or doubling up the graphite brace will make the car react quicker to steering input, & change direction faster. Raising the graphite brace off of the aluminum bulkheads by placing a shim under it on the front and rear holes will reduce response.
Great tip: Does this also apply if you use the turnbuckle instead of the graphite, adding shims will make the car react slower? Or different principle altogether?
Thanks in advance.

Alex told me recently that he has been opting for the solid alum chassis for all carpet racing. This year's solid chassis has more flex than last year because of the cutout under the back of the battery, and the fact the swing rack is moved back. So more flex in the chassis overall.

Many thanks for all the responses, much appreciated.
will be participating in the 17.t blinky class of TITC (Bangkok) next month at the newly renovated outdoor asphalt Infinity track where people have been saying that the grip is really high, thus the question on the turnbuckle brace.
Was thinking of raising the turnbuckle just for the sake of it not touching the belts, but if it would have a major difference in performance, then there's no other option left than to sanding the plastic parts

pretty sure R Dodge is referring to the Xray SOLID aluminum chassis. As far as flex goes, the chassis are as follows:
Softest: Carbon
Medium: Flex Aluminum
Hard: Solid Aluminum
I think the point he was making is that the 17 solid chassis has more flex than previous years, while still being the stiffest offering for the car.
And from what he said, Alex has opted to run the solid chassis for most carpet events, as the little flex that the solid chassis does have seems to be enough for him to be competitive.

For what it's worth, I had a fantastic raceday Saturday with the box setup (or close enough)... what a car oh my what a car, both fast and easy to drive. Best thing I had ever driven, really 
If it weren't for one darn ECS coming loose in a qualifier, that would have been almost perfect. As the outer pin ran off, it shredded a c-hub, plus the bone is shot where the "link-ball" connects from the axle, too. Having polled a few mates running the same car, this is a not-so-uncommon issue. What aftermarket, circlips-based 52mm DCJ's do you guys recommend beyond RSD's? Exact part-refs would be fantastic. thanks in advance.
Also, sharing experience about shock diaphragms (remember the conversation from a few pages ago?). Yokomo bladders work well and don't swell with Losi oil, so it's a go for me, thanks to whoever gave me that tip. they are a tad stiffer though, so rebound settings are to be adapted. Interestingly, one of my xray mates confirmed that his original shock diaphragms don't swell - he's using hudy oils so there is some truth to the discussion from before. The bottom line is, by using Losi oils instead of xray/hudy oils I can finance a lifelong supply of yokomo bladders
Lastly, I confirm some of the camber link screws on the top-bulkheads tend to come loose. This is really really weird. Even with proper tools... so check them out often rather than loctiting them
Still an amazing car nonetheless... almost drives itself!
Thanks,
Paul
