Interesting day at the track today:

First off I got tossed out after two passes for my factory aluminum spare front wheels not being NHRA compliant. Evidently NO factory spare wheels are technically approved since they are not tested/rated to the speeds seen at the track. Good news was that since they missed the wheels at tech they refunded my $$ and gave me a pass to return for free. I've been running these wheels at the track for about 10 years and never had an issue before but the rule in the NHRA book was pretty clear and explicit.

Second I managed a new personal best pass before getting tossed 10.516 @ 128.11 with a 1.449 60' so that was pretty exciting.:D

I also took a video from under the car of the new rear end at work:

This was not of the best pass but I think this pass was 10.57....I surprised just how little the suspension moves. I need to educate myself now on making adjustments to the setup to maximize things.

Very cool. I am running spares for front skinnies. Wonder if clay city will object to them someday. Good times

Sweet run, Great job. Congrads on your new best;) I am iffy on them factory rims I have not run them since 110 traps I have since hit 120 and think I am going to sell them.

I've been griped at before at Gateway for the aluminum spare wheels, but I actually pulled out my NHRA rulebook to show the inspector that the wheels are indeed legal per General Regulations, Section 20:5:2. Spare tires are not legal.

The title of section 20:5 is Tires & Wheels even thought the title of the following paragraph 20:5:1 says tires. The track said that because of the name of the section it applied to both wheels and tires.

Very nice

Kind of had a F1 feel to the soundtrack.

20:5:1 contains Tires. 20:5:2 contains wheels. Only 20:5:1 mentions anything about "spares". The inspector is incorrect.

I looked at the book and changed my post to correct the section numbers and titles.

I agree with you since the subparagraph on wheels says nothing about the spare wheels and its the subparagraph on tires the excludes spare tires but I could not win the argument at the track.

Nice times Brian

That stinks about the wheels....I simply don't understand their logic on that one. I've been sitting on a pair of those wheels for a few years now and it'll be a bummer if they don't let me use them. The tires are obviously understandable, but not the wheels. If you ever go back and talk some sense into them, let me know. Otherwise I'll be in the market for something else as well.

I've emailed the tech department at three different tracks for their opinion. Seems clear to me but what do I know. I'll let you guys know when I hear back from them.

Camera was mounted to the frame rail on a sticky mount that I backed up with some wire ties....seemed to work ok without to much vibration.

I'm surprised that they would even "know" that they were factory spares. Anyhow, let us know what you hear.

So the track passed my wheel question on to Rick Campbell the NHRA Northeast Division Technical Director. His response was:

"The OEM spare wheels and tires are designed to run together and not separately. The spare tires are not compatible with other wheels and the spare wheels are also not compatible with other tires."

I guess in the eyes of the NHRA the spare wheels/tires are an assembly, can only be used as such and are not allowed either as an assembly or individually.

I have not yet heard back from the tech people at the two other tracks I sent messages to. But at least I know this is not a local track thing I now have a ruling from an NHRA official.

I've also now heard back from another track who's tech director has never had this question come up in the past and who on reading the rule thought I was OK but he was going to go to NHRA for a ruling as well.

Awesome job Buddy!

Guess this means you won't be changing out broken half-shafts at the Shootout.

So the tech director at the second track called the same dude at the NHRA and got the same answer.

Good Lord!!!!!!!!

Been there done that. Had to put stock fronts on in the middle of race at Maple Grove in the early 2000s. Had the same argument, lost, threw the stockers on and proceeded to win the race! That was actually my first win and felt even better as it was kinda like a F-U to the tech guy who made a big deal about it!

Tech is there to keep everyone safe, not to hope we fail. They deserve a big thanks for an otherwise thankless job, I think.

And good job on that first win.

I've talked to the tech guys at three tracks. The one where I was cited which is more of a local type track and two others that both hold NHRA national events and neither of the other tracks was aware of the rule, however both contacted the NHRA and came to the same conclusion that the space saver wheels were NOT allowed regardless of what the rule book seems to imply.

It seems like the type of deal where you can get away with space saver wheels since it not a well known rule but if you are flagged then you are stuck.

For most of the people in this club who only race a few times a year I would stick with the space savers....for me I'm going to bite the bullet and upgrade.

That's awesome Brian! I'm glad to see it all worked out for you. The less the suspension moves the better. If you hook with that low of travel, then you have a lot more that you can throw at it. What gears are you running? If you get to a point where you just raise your launch RPM to get 60 foot then you're more prone to spin as opposed to increasing torque multiplication from gear change. Converter plays a good part in it too.

Other than changing parts, just start cranking the leave RPM up and finding the point where you spin. From this video looks like you'll be changing the compression shock adjustment, possibly changing rear springs. Your extension adjustment is pretty good looking for bias ply tires. If you get to a slippery track then softening the extension adjustment will let the tires plant a little harder, but if it's too hard it will wad up the middle of the tire and make you spin.

Just some tips!

I'd have to check my notes but I'm pretty sure on the pass in the video I left at 4200rpm off the trans brake with 13psi in the tires. Shocks were set at the mid point of the adjustment for both extension and compression. I run a 3.73 gear and trap at a little under 6k rpm.

The front tire thing is just a matter of NHRA throwing their weight around which is fine, it's their gig. Space saver wheels such as we use are DOT approved which is to say lot more stringent set of requirements than the crap that is often passed off as "drag race only". A lot of drag race wheels and tires are just pure junk really. It's also funny that we see 9 sec cars running street tires on the fronts of their cars that are often rated for only 112mph, or that we see drag racing tires that have no speed rating whatsoever. How does that even work?

Oh, and thanks Brian for making an issue out of this so now we ALL have to upgrade. :p J/K

No problem....I think every track in the Northeast is now up to speed on this rule.

I get not running the spare tires but the wheels!!!! Come on..........

Previous best was 10.60 at about the same speed. That was not my best 60' though!!

Brian,

I'd be thrilled with 1.5 60fts...1.4s is dream stuff for my cars. Haven't see anything better than low 1.6s since I stopped using nitrous.
