I'm looking to get some small (~1/8" or ~3mm) hub centric wheel spacers made by a local shop (5x114.5 only, sorry 4-lug guys
). I contacted the shop and they said all I need is to provide the dimensions, material and quantity and they would get back to me on a quote and lead time. They are a tooling setup shop so this would not be mass production, but obviously the more parts, the cheaper.
My intent is to use them on the front as my current setup is just barely making contact with the spring perch but is also very near the fender so a large spacer isn't practical (Enkei RPF1's 16x8 +32 wheels, 225/50R16 Toyo T1R tires and Stance GR+ coilovers). This would also help people with contact issues with the larger diameter drop springs like the Tanabe's and Tein's...
After I gain some ability to adjust the camber on the rear I will also possibly be looking into some larger spacers for the rear (~3/8 or ~10mm).
I have all the dimensions needed for a hubcentric spacer except the outer diameter. I'm not sure if I want to match the wheel or hub outer diameter, so input here is appreciated. See the sketch below for the current design (ignore the 175 mm outer diameter - that is just for reference at this time).
One thing I have not yet decided is the material. I am currently thinking Al (6061?) but the 1/8" makes me worried. I didn't want to get into the more exotic stuff (magnesium infused whatever) to keep price down, but I also don't want mild steel for the obvious corrosion concerns. Any input would be appreciated.
Just curious if anyone would be interested. I would need to know pretty quickly actually (will be sending the final drawing on Monday), but I will inquire anyway on some larger quantities (10, 20, etc.).
