Can you point me to your favorite source of car numbers? And say why you like them? Good quality, customer service, last longer, stay on better, what?

They have to stay on at speeds over 145 because I run my car at Road Atlanta, which has a long, high speed section with "turns" that do not require coming off full throttle.

I'd like to know they are reusable. Up until now I have used the organization's numbers.

I was planning to get magnetic, because I assumed that those might look great and last for years, but there is a closed thread here where several posted that they have had magnetic come off at lower speeds that my car will be doing, so I am leaning away from those now.

Could you share your experiences with me and share where you got your numbers? Good and bad experiences both welcome. Thank you in advance.

Magnetic will not stay put unless you tape them on. Your best best is to get a good vinyl stick on one you like,. I had my buddy make me a custom set and they have been on for about 5 years or longer now

I like TrackPlacks. Fast turnaround.

5 years?

Do yours stay on full time? I ask because mine is mainly a street car, not mainly a track car. These numbers have to come off when I am finished with HPDE, which was the original attraction to magnetic. Do yours come off? Can they be re-used?

Neat. Those look very nice. I have also never seen or heard of that source. So if I spend the 65-75 bucks, how long will they last, approximately, in your experience?

I just switched to TrackPlacks earlier this year when I switched numbers. I put mine on this past February and they still look great through ~10 track days but I have not removed them and re-applied them. They are a high quality number imo.

They will peel right off but they are not reusable. I don’t drive my car on the streets much. I also don’t care if I have numbers on my car. It’s a calling sign to other track rats

I use https://www.autocrossdigits.com/ (know the owner personally) - the right choice for you might be low tack removable vinyl numbers

I also use autocrossdigits, but I added some magnetic insurance for the high-speed events. I documented it here. It's been working great for me at HPDE events.

Calling @DaveW for recommendations. He runs Solo Performance Specialties (SPS) and can supply TMO-logo and other number/class panels.

The info in the Materials selector on that page says magnetic is generally good up to 70mph, but can be used at higher speeds if you use tape to seal the leading edge of the panel to the car and keep air from getting underneath it.

One trick I use is to bevel the edges of the magnetic material at 45 deg., so air doesn't "stack up" at a 90 deg. edge and cause a high-pressure area that's more likely to peel the magnet off the car.

Given air flow vortices down the side of the car caused by the windshield, mirrors, wheel opening, etc., for high speed I'd tape down all the edges with good painter's tape to clean surfaces. I might even go around once with 3/4", press it down well, then go over that with 1-1/2" and press down again.

That is not the correct Internet address for this site.

LOL, no, I meant for this site. trackmustangsonline.com

trackmustangs.com is not a working url

LOL. It's been a few years since we set up that panel, but IIRC I just used a design that @Chris sent me. I will check with him on that

I have obviously gone full vinyl on mine and have never taken it off, that said I started with a set of re-usable vinyl from Dave W before moving to a magnetic placard set. The placards worked great for autocross, but obviously the adhesion of the vinyl is superior. If you're going magnetic, I'd suggest as large of a placard as possible to get as much adhesion as possible and would still tape the front or even do a quick layer of cheap clear PPF over the entire door quickly. The biggest issue with re-usable is making sure that the car is clean when applying and you're best served to clean the area around the car and your hands before pulling them off and putting them onto their backing pieces. Also make sure they get firmly sealed onto the backing material for storage so they don't get dirt and grit on the adhesive. I've only tested these to around 100mph personally, but I see no reason why they'd ever come loose.

Magnetic


Re-usable adhesive

Get my decals and more from DaveW................my son and I have bought gloves, helmets, fuel jugs, shoes, etc. from Solo Performance over the years.

The business was started to provide decals for racers so pretty hard to go wrong and Dave and Liz are great folks who support alot of racing activities and events.

Agree with vinyl vs magnetic. My magnetic’s did not stay on past 120 mph. Bought some vinyl, made a number template, cut out several sets of numbers, and put new numbers on at beginning of HPDE season & remove at end so don’t have numbers during winter driving. Average cost is $5 a set & they don’t come off even at 145+ mph.

My old “reliable” trackdecals has gone belly up. There is someone using trackdecal but use your own judgement there. My avatar photo is trackdecals & my new ones are the racegraphics which lets you “build” a custom set.

Are yours permanent vinyl or one time use or reusable or magnetic?

I bought the little magnets mentioned in the closed "car numbers" thread. I can attest those suckers are very, VERY strong magnets. If you don't mind holding down your numbers with a couple of these magnets I absolutely guarantee they won't come off no matter how fast you go.
