I plan on using the affordable Big Donkey resin cast Vintage Monogram Midget - and with very little fitting it works almost perfectly on the
Sprints Plus chassis. For my build - I will add brass nerf bars, and bumpers, and some pieces that sort of look like radius arms in an effort to match the look of original Monogram slot car as shown below:
MONOGRAM 110 OFFY MIDGET RACER –Anyway - I will run "Daytona Pro-Track" 3/4 inch (.750s) on the front and .880s on the back. It puts the chassis about where it should be off the deck, and looks about right when compared to the old advert I posted up above. I think I will trim the width of the rears and fronts to "get the look" even better - those midgets ran some pretty small and narrow tires back in the day.
There are original-style *exact-repros* of the 60s Monogram rubber tires and rims available online - and that would be absolutely the most correct. Since I was hoping to get the South Shore Speedway racers (the local "underground" home racing oval track) interested - and since they all like to run *real fast* and essentially race "commercial" style slot cars - I knew contemporary foam and some brasswork bumpers/nerfs would be a must.
In any case - the heavier resin body should work well with the heavier brass chassis.
I will be posting my own Proxy Midget build - I have things to show but I just haven't taken the pix and made the time to post...
