Looking for custom built 13" road racing wheels| Grassroots Motorsports forum |

I'm trying to find rather specific 13" wheel offerings. Anyone know of some? I've search eBay endlessly, searched Google into the upteenth results page. I remember 20 years ago there were a handful of 13s available, but you know, every car can fit steamrollers these days.

1997 Geo Metro

4x114.3 PCD (I've considered re-drilling the hubs b'c there are a few 4x100 13" wheels)
Need roughly a -35ET on a 5.5" wheel (plenty of 13" options from AE86s but they only have -20ET and the Geo fenders are very shallow)
Looking to run the 185/60R13 tire choices, so wheel widths from 5-7" are ideal
fenders do not adequately fit 195/50R15s and 14" sizes are not well supported for competition tires </= 200 UTQG

There are a number of companies selling 13" drag wheels, but they're too wide for this application and .... maybe not safe for hopping curbs on a roadcourse.

Any leads are appreciated!

Been through their site, and while they do not appear to have anything that fits, I've emailed them directly to ask. Closest they offer is a 13x7 but with no offset. Thank you for the suggestion though, I'll report back if they can make something work.

Try https://www.wheel-size.com/

click on the "By rim size" tab, maybe see if there is something else same/similar/workable

13 inch is a common mini stock size. You can get whatever you need from Basset.

I love that site, probably visit once a week to investigate something. The issues abound here. 13" wheels are hard to come by but there's a few competition grade tires. 14" wheels are harder to find and there's like no comp tires. The 15"s are where the variety is at with tires, but the fenders only fit a 195/45R15 and the ONLY tire on the market is only 240 UTQG with silly soft sidewalls, it even sucks in the rain. Also, in the 15" category, the tire OD is getting to be over an inch bigger, making everything worse (ride height, arm angle, fender clearance, Revs/mile, etc).

Sadly those run zero or less offset. Just looked through their site. Thank you for the suggestion though. If I'm wrong and didn't see -Offset wheels, please let me know.

I had a set built to my specs by Marsh Racing Wheels. 13X9, custom backset, with a FB bolt pattern. They would pretty much build whatever you wanted and they were pretty cheap. It looks like the man running it passed away and the company is gone. That makes me a little sad.

That was an emotional roller coaster.

13x5.5 on a 35mm offset (I assume you mean positive offset, negative offset would have the wheels sticking out a ton) translates to roughly 4.25-4.5" backspacing assuming a 1/2"-ish wide rim lip. Backspacing takes the whole wheel including the rim lip into account, so you have to add roughly half an inch after you divide the width in half and add the offset.

Diamond Racing Wheels can do 13x7 in up to 4.5" backspacing, or 13x6 in up to 3.5". (They're also a GRM advertiser!)

Summit has 13x5.5 aluminum Konigs that are supposedly 38mm offset and 4.75" backspacing, which doesn't make much sense...

They also have steel 13x6 Bart racing wheels with 4" backspacing (12mm offset)

Pretty sure they will make any offset you want. You can also check Bart.

I would say reach out to keizer, but they just lost literally half their inventory and all their manufacturing ability to a fire the other week and might be unable to help for a few months.

Decent stuff that's really light and affordable. I'm running keizers on my fmod with custom wheel centers. For my car on 10 inch wheels I can assemble the rim on the tire (uses silicone caulking to seal overnight before installing valve core and inflating) so no tire shops needed.
