An unrealistic wing is one where the side dams are the same height as the wing, they would be a lot more realistic looking if the side dams were 20mm....just saying.

Past 10mm the drag increases tremendously, slowing down those weak 21.5t motors to a crawl, and there are other ways to gain back some rear traction to make up the difference. 20mm rear wings might not be such an advantage after all if you know how to setup your Usgt car....

Avoiding the discs on this track is difficult at best if you want to turn a good lap time. I'm sure I need to adjust my roll centers, but I was wondering if running a front spool isn't also contributing to the rolling issue.

Any suggestions would be appreciated.

Thanks.
Rolling from impacting a corner dot is different to a traction roll. It's important to know the distinction as the solution is likely to be different.

For T2 style wings, I can understand the 10mm rule. But if a person is using the wing that came with the GT body they purchased, I would think that wing is reasonable & realistic if trimmed to the mold lines.

Just my opinion as someone that mostly watches USGT and would like to see it continue growing with new racers. I appreciate the effort you guys have put into the rules; I understand how hard it is to please everyone

I did trim up a PFM10 last year with a 10mm tall wing, and the full size side dams looked badass on it

Completely agree that full size wings look goofy on a USGT car. Even the wings that come with the PF bodies, of not trimmed down look entirely to large. But once trimmed to proper hieght, give the scale look that separated GT from TC. But 10mm sidedams take away from that look. Larger, scale sidedams look so much better. I said scale, not the huge rectangles that come with TC wings. But something like on my Ford GT amd P-zero. Yes I realize not technically legal for official events, but they look better than having nothing. And of scale sidedams are t legal, then neither should bodies with translucent one coat paint jobs and no detail decals.

I should have added that my car is on the edge of traction rolling before I'm clipping the plows discs. I'll probably raise the inner hinge pins on the car as they currently are as low/as close to the chassis as they can go.

----------

To add to the body appearance discussion, I just want the cars I race to feel like it is a "race car". Regardless of paint schemes/colors, there are some things that set race cars apart from most street cars.
- Major sponsor decals (usually on largest surfaces of car)
- Minor sponsor decals
- Participant number located on various surfaces of car
- Large painted "sun visor" area at the top of the front windshield/screen (does not apply to open cockpit cars). This area usually has a race series OR sponsorship decal
- Functional front/rear lights OR replica decals (typical in oval racing & R/C racing)

If an R/C car has all of the right visual cues, then it "feels" like a race car to me regardless of the type of paint scheme on it. The top picture of the USGT #112 car above this post hits all the right marks for me to look like a race car. The bottom picture just looks like another generic touring car because it is missing racing numbers in the expected locations (such as doors on protoype/sedan style race cars).

One final point. I don't expect everyone to have the time, resources, or budget to replicate realistic paint schemes in VTA or USGT. I would however DEMAND that the people who are competing at the top level of these classes at least make an effort to make their cars appear to be race cars. It is disappointing to attend large events and see that some of the fastest drivers have made zero effort to make their cars fit the look these classes are trying to achieve.

Realistic paintjobs for VTA is pretty easy. The race team paint back then wasn't anything sophisticated. Annoyingly, nobody has taken note that the paintjob I have on my 'cuda is the same as AAR ran back in the 70s. But... that's just me being annoyed.

Realistic paint on USGT is a lot harder. They're from the era (that includes today) where it's mostly sponsor logos, rather than ~a paint scheme~.

One of the big ways "real cars" get all stickered up, is from contingency decals, and from "series" decals. Nascar has a decal package everyone must run. In drag racing, the majority of the stickers you see are from the contingency deals. Maybe... just maybe... we could talk to the USVTA people and figure out what that decal set should look like, and get it produced? Sold at cost... Maybe given away at big events? It would go a long ways towards encouraging people to make their cars look like those race cars.

That reminds me, I need a driver figure for my VTA car...

While I will somewhat disagree about my PZero body . i I didn’t think the number plates on the sides of the car blended very well. So I placed them on the rear “window” where I felt they more naturally fit the paint scheme. But, I completely agree with you about the paint jobs on the cars. You put it much more eloquently than I did. It should “feel” and appare to be a race car. And I cannot agree with you more than how annoying it is to see anyone in the A-main at any large event l, much less podium winners, with one color wonders. Hopefully the body weight rule will help alleviate some of that.

There is is no rule.

I was referring to the new body weight rule that Scotty Ernst and the Euro Touring series has implemented and am thinking it would be a good thing to bring over to the US for all classes to help get rid of the one coat wonders.

Bronson,
IMO (for what it's worth) we have both seen tracks that look the other way for any number of rules violations (weight, voltage, ride height, correct/legal body, battery heating, etc). It's tough getting people to work tech at many small tracks and we are going to add weighing the body? For "big" races, I like the idea. It's not that I don't like the idea for club races, but tracks don't want to deny customers and no one likes working tech. Just my $0.02.

Agreed Scott, but it’s a lot easier to put a body in a scale, than it is to deal with handing out motors and managing them every race, but that doesn’t seem to be slowing that god aweful trend any.

Reminds me of what ETS just implemented with their 90gr rule

Still think 100gr for any USGT type trophy race that is running tech is realistic. I wouldn't expect club racing to matter in this regard just like club races here don't weigh cars.

Looks like there are a few 190mm Ford GT's available right now on ProtoForms website
