Mondial QV & 348 wheels??

Birdman has done this on my old car. Perhaps he'll chime in! Welcome!

Oh jeez, from the top of my head I think the fronts are 17/50/215, and the rears are 17/45/255 or maybe it's 265?

 

83 QV Mondial, I have 348 wheels on mine. 3/4" spacer in rear none in front. 215/50 and 255/45.

These work out to within 1/4" larger in diameter than the TRX 240's that came standard on mine.

Simple answer to this is.......the wheels just bolt straight on and you'll need as set of 348 bolts from Hill engineeringfor around £225

 

John,
Email sent. I agree that they just bolt on with the 348 bolts but the rear lines up better with a spacer.

My 2cents.

I love dredging up old threads! I know this thread is 15 years old, but...
--I have a set of 348 wheels to go on my '84 Mondial QV.
--I understand from this thread (and several others) that the wheels "just bolt on", but that neither the stock Mondial bolts nor the stock 348 bolts will work. Instead, you need longer versions of the 348 bolts, specifically:
--17mm hex head, M14x1.5 thread, ball seat, 58mm in front, 55mm in back.

But in this thread "hackrider" advocates putting a 3/4" spacer on the back so the wheels fit the wheel wells better. 3/4" is around 19mm. Spacers seem to be in mm, so a 20mm spacer (like this? https://www.ebay.com/itm/202663090125) should do the trick, assuming that center flange size is ok....but then I'd need 75mm lug bolts? Those seem pretty extreme, though Hill Engineering actually has lengths up to 80mm. Anyone still active here with a Mondial with 348 wheels? Are you running spacers in back? I'd love to see pics of cars without spacers (hackrider, aka Dave, nicely provided a pic of the wheels with 3/4" spacers).

I see "58mm in front, 55mm in back" in several threads, which suggests most people are using the wheels without spacers?

Thanks!

 

I have a set of 348 wheels I plan to put on one of my mondials. I think they look better with the 20mm spacers.

take your 348 wheels, take a piece of 3/4" thick wood, drill a hole in the wood to simulate the spacer. run one of the lugs you have on hand and see how much more length you need to go into the hub. Maybe save a little back and forth when ordering.

This photo (metallic red w/helicopter in background) is without spacers in rear?

Thanks!

 

I'm pretty sure yes without

 

My posting above erroneously says ball seat. They are cone seat. Cone seat. Cone seat! I wish the forum would let me edit the original post. Don't want to mislead anyone.

Also: I don't want to sound cheap, but at this time, Hill Engineering wants 11.50 (pounds, not dollars) per bolt, so 600 pounds/ $830 shipped for the set.

A company called Otis Inc LA, a US importer which mostly specializes in lug nuts and lug bolts from European manufacturers, has M14x1.5 thread, cone seat, 55mm for the backs (to not foul the parking brake), and 60mm for the fronts (2mm longer than needed, but no parking brake to get in the way, so longer should be no problem). Manufacturer is "RAD" from Germany, not a generic Chinese bolt of dubious quality from an anonymous factory. These are NOT CHROME and do not use a 22mm socket, but they are also 1/10 the price at $2 per bolt. With shipping, my total was $56. For now, these will be just fine for me, I think. If the 17mm non-chromed heads bug me, I can cap them with chrome lug bolt covers.
