Mag Products Wheels - info, ideas

Post by cgranju » Mon Mar 12, 2018 11:15 pm

A little while ago, I got these wheels from a friend. These were bolted onto an X1/9 and it was actually for these wheels he bought the car (parts car, basically). From what I can see, it looks like the wheels were probably bolted on using some mix of tapered bolts/nuts & flat ones...some of the bores have a washer that looks like a flat/shouldered type bolt/nut was used & others look like someone has torqued down a tapered bolt/nut. These are 13 x6 wheels and like any good Fiat guy, the last thing I really need is more wheels, but I'd really like to clean these up & be able to use them. The bore for studs is a smaller diameter than any shouldered or "mag" type wheel nut I can find uses, but larger than 12mm. I figured if I really like these, I can have a 60 degree taper cut into each bore, or I could find the proper flat washers IF I could find mag wheel nuts that fit into these bores. So, none of this is urgent, but I was moving these yesterday & figured I'd snap some photos & share here to see if any of you old timers (ha!) have some experience with these Mag Products wheels. Here are some photos, along w/ a cool ad for them...actually, I don't know if these are "Mag Products" or "G.T." wheels, but clearly they are made in England.

and for fun, these are also on deck, 14" Sportstars...once the gold paint is all off I don't know whether they will be restored to the original finish or return to gold for a while.

The Mag wheels look cool and based on your pictures I would guess they take shouldered bolts. Sports stars are always appreciated.

Carl, it would appear they are made to, but the shouldered nuts you typically find (maybe, only find) have a shank diameter of .68" & these have bores around .62 or something like that. It's been a while since I measured, but when I first got these I was pretty excited to use them & then found out I was going to need to find some "exotic" shouldered wheel nuts or have them machined a bit.

There is a shop up in Maryland call Ye Old Wheel Shop that is the go to place for wheel repair, they even welded up a crack in some magnesium wheels I had. I wonder if a place like that could properly bore out the holes for the larger shank standard shouldered wheel bolts.

Nice find! 8-)

"Mag Products" was the maker & "GT" was the wheel model name, often marketed under the Dunlop brand name. Back in the late '60's & early '70's, Rich Motors Fiat Abarth imported & sold them, also offered as an optional wheel on the Fiat 850-based OTAS cars that they also imported & sold.

IIRC correctly, they used a unique (narrow) shank-style lugbolt with a flat washer, but you could also have them fitted with tapered steel inserts to allow use of regular Fiat (conical-style) lugbolts, similar to what was done with the old 4-spoke Fiat-Roosevelt Libre wheels.

Thanks! that's great information. Yes, I don't recall the diameter of the bore, but it's probably in the 15mm range. I got at least one lead for a local machine shop that might be able to either cut the bores to the more common 17.5mm or (preferably...I could probably give a shop about 24 wheels for this job) install tapered inserts. Guess I need to locate tapered inserts....

Apple motors was doing this work for all the Roosevelt wheels that had unique sized shouldered bolts, they installed steel inserts which took the standard tapered lug bolt/nuts. I had them do this to a set of Roosevelts but that was a ton of years ago.

that is what I need. I found a local machine shop who appears to be competent to open the bore on these (also could do another set of Revolutions I have that have the old 15.8mm bore) to use a common flat/shouldered nut, but it would be worthwhile to have tapered inserts installed if I can find someone to do it. I'm not sure any set I have quite warrants a trip (for the wheels) out of state & back.
