Here's a list of some that could possibly be tried if anyone has the $$$$ and the mean (CNC machine).
Polyetheretherketone - Black color, R 126 hardness very pricey, $130 - $140 per ft.
Polyamide - Black color, E70 hardness (machine with carbide tooling only) very pricey ~$175 per ft.
Polyetherimide - Transparent amber color, R 125 hardness, ~$35 per ft.
Polyphenyle Oxide - Transparent amber color, R 119 hardness ~ $12 per ft.
Polycarbonate - Clear, R 118 hardness, ~ $12 per ft.
Those may be some possible choices. Of course there is Delrin also. I would have to dabble with the Delrin and cheaper stuff if I ever go down this road.

I was trying to see if I could get anything more out of Smooth Criminal and I totally messed up the front wheel. It looks as though I'll be out of the Super Mod race this time. Too busy finishing Door Slammer to mess with it.

I would have to dabble with the Delrin and cheaper stuff if I ever go down this road. I'll stay on topic I promise. The SINTIMID material I mentioned previously is a "brand" of polyimide (or polyamide). It would be a good material, but a rod of 1.5" x 15" = $1,454.32...or $100/in. www.acetal-rod-sheet.com/polyimide-rod.htmSo, it was sort of a joke...unless you can get some "drop offs" pieces or scrap somewhere. I currently have the Polyetheretherketone (PEEK) material for my wheels. It has a filler material as well. I hope to get some machine time soon to build these wheels. I got lucky and got this material from a friend. My second choice was Polyetherimide (or better sourced under the name ULTEM). You can find it at reasonable costs as you indicate. Since you described the color and transparency, I don't feel like I am letting out any secrets. Wheels of this color appear one of the MMM super mod cars...which happens to hold a record. Obviously the results speak well for PEI Are you guys making the wheels out of thin sheet...and cutting out "rounds"...or are machining them from rod and polishing them? The MMM wheels looks like they would be quite easily fabricated from a sheet. the mmm wheels are running bearings so the wheels material does not have much to do with the speed... beakerboys racing set the track record at blue grass with the HoleShots SB's took second place to a 34 mm wheels which is to tall for pddr's race. I set the track record at the nationals with a HoleShot sb on the front dom and 2 special mod wheels converted on the rear just because I had them and ran out of time...

You were running experimental wheels on the rear, that's why I couldn't catch you. That explains the 7 thousands difference and why I could only muster 2 nd place at the Nationals. Cheater! ;D Just kidding..... Gotta mess with you Glenn, can't beat you on the track so gotta play sike games with you.

Gotta mess with you Glenn, can't beat you on the track so gotta play sike games with you. the funny thing is that with the testing with the holeshots and the wheels I had on the upngon car is they ran with in .001 of each other. the holeshots was faster then i played with the alignment on the front dom and starting running faster with the other wheels, so when the car was running record times do you think I was about to take the car apart plus it was the day before I had to leave on the plane... lol ;D now that I am back you bet I will test some more... I just got skills lucky... the car ran faster than I was expecting...

Awesome job When I mentioned The BGN champion car "Tuk" had 34mm wheels (no maximum dia in PWD rules), it was a guess. I knew they were bigger than 31mm but not absolutely sure on the exact diameter. I should have known the O.D. before I said what I thought they were. I measured them *** *** TODAY *** *** & they are just a tad under 32mm. Sorry for the mis-info I made them out of some $0.70 washers from the hardware store that started out @ 34mm. Had the same washers on my 3rd place car in NC except they were cut down to 31mm. Again I apologize for the mis-info

Again I apologize for the mis-info DaPine, So let me get this straight...You had $.70 wheels and ?? bearings for a total cost of $$ NOT TOO MUCH? Amazing! Where do we sign up for a set or two? I wonder not how many people you beat, but how many dollars you beat....!!! ;D Racing on a budget......Priceless!!!

I wonder not how many people you beat, but how many dollars you beat....!!! ;D Racing on a budget......Priceless!!! .70 for the washers how much was the " bearings "... how long did it take to turn the wheels and then set the wheels up... The bearings we use are abec 5's and they cost 15.00 ea... do the math if you use double, 15.00 x 6 = 90.00 plus .50 for BSA wheels then time to turn them on the cnc lathe to create the HoleShot, then time to center drill, then time to cone the hub down, then time to set the bearings in the wheels then time to test spin for good set... The HoleShots sb's start out at .50 for each wheel before they become a HoleShot sb... Glenn

Yes Glenn, lots & lots of time to turn washers into wheels not counting how many end up in the garbage can or embeded in the drywall . How much were the bearings??? Good luck everyone racing this Saturday
