I would like to make a proposal to the NTRA powers that be. After running the Pro Street X2 build class this year at the Winter Nats, I would like the addition of traction magnets to be considered. At the minimum recommended voltage of 18v and on a sectioned track such as Bear Creek, I experienced several deslots due to lack of downforce (some were due to wheels out of balance). This may not have occurred at one of the continuous rail tracks and another type tire could have been used to allow slippage....I realize these things. But we have other similar builds...such as 4g Pro Mod or even 4g Econo Dragster that allow their use. Maybe limit it to one or something like that. Just an observation and suggestion.

RACERS TAKE NOTICE!
In response to Racemaster Jeff's observations, proposal, and suggestion, the following
modifications have been applied to X2 and X3 chassis builds and are effective immediately:

Former chassis build:
X2 - no traction magnets allowed; no wheelie bars allowed.

X3 - no traction magnets allowed; wheelie bars allowed not to exceed 1-1/2" in length as measured from rear axle.

Modified chassis build:
X2 - In light of observations made during 2015 NTRA Winter National the following changes have been applied:
* Traction magnets permitted.
* Wheelie bars permitted not to exceed 1-1/2" in length as measured from rear axle.
* Note - only one or the other of the performance techniques described above may be used
on a single chassis.
Racers choice - this will provide flexibility in options while still requiring an adherence to some limitation. Also will allow comparison of technique.

X3 - use of traction magnets now permitted and may be used in conjunction with wheelie bars.

TAKE HEED RACERS!
Note - X3 build is used in April NTRA event and the above changes will be in affect. X2 race
is scheduled for August event.
