Late model front end question;blue,black grey

[talclipse]

Per the guys in Shinnston the only components from a previous car you can utilize on the new cars is the LF upper and lower control arm. EVERYTHING else is different.

If one of these new cars goes out and wins this weekend at Eldora I figure you will be seeing a lot of 09, 10, 11 cars for sale/ being traded in.

was told that a orange front was at tyler county and finished 3 or 4

Orange front end -

Timing for a new front end release is important. Like the release of a new iPhone, it must be consciously staged. I think Rocket is doing at great job marketing this change.

Working backward from a target release date:
• World 100 time-frame for public announcement which is important for chassis selection for the following year. (Sept 10 '11)
• keep exposure to a few so that relative performance is unknown compared to the Blue/Gray (Aug10 '11– Sept 4 '11)
• Word slips out for several months during testing to finalized pre-production components, builds anticipation and stalls some decisions to change chassis builders (Feb '11 – Aug '11)
• Recognize that the product line is becoming dated and that producing HOPE for racers critical in this market place (Sept '10– Dec '10). Other vehicles have become desirable in the market, even though your performace is equal or better with old design (Victory Circle, MB2, Warrior). New market requirements say that the vehicle platform must be equal or better in performance to the current car or Consumer Reports will move you to the "not recommended" category. Good news for Rocket that they can rely on all new testing to be applied the new car, plus normal technology evolution that will make any car better and will be used by top racers that only use your newest cars.

Does this mean we can expect to see a new orange front rocket chassis misplaced at a bar just down the road from the rocket shop?

I was told that the only big difference between the two cars where the blue front end is built with the right front ahead and the black front end is built heads up. Don't know if there is any truth to that since I havent measured it myself, but moving your A arms heights changes roll center for the most part surely there is more difference in these cars than just roll center. I would also like to know what is built into these cars that are different.


Thanks.

I recently contacted Rocket about a chassis seminar cause I felt it would be interesting to learn more about why they color coded rather than give specific measurements. My experience being mostly karting realize much is done to keep things simple for the weekend warrior.
I felt compelled to reply on the post cause many of the local runners I have been around tend to jack wieght on latemodels which I believe because of deceleration & changing track conditions creates an unpredictable effect. I think many in karts may believe I did this on karts but I constantly scaled to reset cross weight to my 1 constant rate. I believe the same applies to late models with given spring rates(I was not above chop-cut rebuild to change spring rates of a kart). I also believe stagger is figured by track size, vehicle track width, percentage of track straight away footage vs turn footage but I may be wrong a lot of time has passed since I attempted to figure the formula or looked at the formula. I would have to refind the equation. I am interested in the front geometry cause on karts after figuring the previous figures the only changes I made was caster/camber. Irealize latemodels are much more involved but as with any experiment limit the variables & improve each week without losing equipment. The track rarely changes con figure ation!

Which upper do you move. The only reason i ask is because I thought the Black had a farther left RC centerline then the blue, which was why the drove yawed out more. Moving the RF up at the inner pivot point would move it farther left correct so moving the LF would make more sense. Can someone tell the full details here?

Yes, a black car has a RC to the left. I do not know where these guys got the misinformation on moving the RF control up will make it drive like a blue car. The mounting points between a blue car and black car are completely different.

[7uptruckracer]

Well moving the RF upper up will shift it farther left it was my understanding the Blue cars weren't as far left as the blacks.......If anything wouldn't i go down or the left up? I guess you could dublicate feel maybe but thats about it
