Formula Drift Professional Drifting Pro-Am Rule#3.3.4
Formula Drift Professional Drifting 2010 Pro-Am Supplemental Rules and Regulations
3.3.4 Front cross member and/or front or rear sub-frame Front and rear sub-frames and cross members must be stock and available on the exact model that is competing in Formula Drift. The subframe must also be mounted in the exact stock location, without being moved in any plane. Front subframes may only be modified to directly allow for oil pan / starter clearance and steering rack relocation.(the reason I would do it) The front subframe must retain intact on at least one major member on one face that spans the entire width of the subframe, thereby keeping the original dimensions of the subframe intact. Any other modifications, cutting, welding, strengthening, etc is not allowed. How do you guys interpit this rule? I see it as this, but Im not too sure as to what XDC wants. Before I contact them I just want to see what you guys think. example of one other one out there. Stock: http://www.ls1fd.net/img/subframe_removal/pic4.jpg http://sphotos.ak.fbcdn.net/hphotos-...6_438411_n.jpg http://sphotos.ak.fbcdn.net/hphotos-..._7154281_n.jpg This is just a thought as my newly built engine sucks and I have a 2jz single starring right at it in the garage. I know a lot of you guys have actually attended a few XDC events and might have a little more insight on tech. I really want to compete this summer but im running out of options and money trying to have a competetive power plant for this season. My 13brew is blowing oil all over the place and I have rebuilt it 4 times already with only 2k miles of actual driving time over a 2 year period. It might be time to replace the engine or scrap the whole project. -Danny- |
XDC won't even look... they DGAF.
|
welds on subframe side definitely wont pass tech @ FD. haha
for pro-am's its just basic tech... if you make FD, and you go to Tech Day @ UTI then they'll pick it apart. but XDC is pretty relaxed as long as safety of competitors, and fans/staff aren't at risk... although i've never been to the first event of the year so maybe that could be why i think that. XDC Vegas was strict, until i passed, then AZ they just checked the tech sticker. |
idk why you didnt have me build your engine.....

The bottom pic =no dice in FD

I'm curious as to the interpretation of this rule as well.
Not that I can/will be competitive with it, but I'm swapping an S13 rack-and-pinion steering setup onto my Starion, and was following FD rules and regs with the buildup, until I saw this rule. Obviously an S13 crossmember doesn't just bolt right in, I would use the Starion mount pads on an S13 crossmember itself with S13 LCAs and tension rods, but that would, according to rules, fail an inspection. |
that would obviously fail do to being from another make car. The subframe pictured here is not the best looking but i like the idea and I think it would fit with the 3.3.4 rule.

From what I've heard there can always be exceptions. The BMI RX8 doesn't have a stock subframe (custom tube frame I believe) and FD tech passed it as long as they moved the motor 6 inches forward out of the firewall. This may be marketing related as having a 4 rotor rx8 in the series is a good "wow" factor.
Before they had to move it http://sphotos.ak.fbcdn.net/hphotos-..._6603614_n.jpg After they moved it http://sphotos.ak.fbcdn.net/hphotos-..._5383070_n.jpg For anyone who's wondering they moved the radiator to the trunk |
I would love to see the underside of that car.
|
I've seen build pics somewhere. I'll try to find them
|
it's amazing to think the bracing to the firewall passed tech...
|
Like I said. Marketing related. I bet if someone who would bring tons of fans and money to the series, like if Jimmy Johnson, or Ken Block decided to join FD, tech would pass anything just to get them on track. Remember we're all just rolling billboards.
As far as the subframe goes use ones that have already been approved as examples Rene Franco did this one for the CX Racing FD https://i163.photobucket.com/albums/...d/DSC00584.jpg https://i163.photobucket.com/albums/...d/DSC00585.jpg https://i163.photobucket.com/albums/...d/DSC00588.jpg https://i163.photobucket.com/albums/...d/DSC00589.jpg https://i163.photobucket.com/albums/...d/DSC00598.jpg That setup was approved by FD tech inspectors https://www.rx7club.com/attachment.p...6&d=1269840531 They probably stick Tony on all the rotary cars |
Yes it did pass. But I sent Tony pics of every thing I was not sure about.
He said this was cool before I went to tech. He did not pass my aluminum front end. We had to add a steel crash bar. Even tho it is not in the rule book any where saying you can not have one. So ask him first. Don't assume it will pass Email is : tech@formulad.com or: tony@driftalliance.com |
good info! ^
