I know there is a way to do this but I don't recall the process....can someone explain how it's done!

I know the X takes 4x98mm wheels. I have a set of LANCIA wheels (4x100mm) and I'd like to know how I can make those fit on the X. The offset and backspacing is fine on those.

I don't really want to install adapters or re-drill the hubs or anything crazy....but isn't there an easier way to "retrofit" 100mm wheels onto an X??

You might not have enough offset to be able to use spacer-adapters, so wobble bolts are probably the best way to go.

they look like what I need to fit the LANCIA wheels on.....has anyone use them with no issues??

Thanks for the information

But if the wheel itself is hub centric, them maybe it's safe.

X1/9 Hubs are 58mm and huncenric wheels are 58.1 mm. I had custom adapters made to go on new hubs and at 58m, they simply will not go on. At 58.1 they are a very snug fit. I found this out by sending a new hub to the guy who made them.

If you have a hub centric wheel, the clamping force of the bolts with wobble bolts may be enough, and probably is, but I would carry a torque wrench with me and check it often during the the first few weeks just to make sure.

If the wheel isn't hubcentric, I personally would not risk it. And if the offest is not greater than 15 mm adpators would set the wheel way outside the fender. 155 mm is the minimum thickness that I've see available for adpaters.

There may be one remaing option to redrilling and tapping. If the wheel's center bore is greater than 60mm or so, I am sure someone could fabricate centering rings that would press on the hub and fit snugly in the wheel, thus making it a hubcentric fit.

Hope that helps give you an idea of what the pros' and cons are.

15 mm, NOT 155 mm, is the minimum thickness for adapters. Sorry for the error.

I used to have a 4x100 daytona wheel which I mounted with wobble bolts. No problems.

modern Lancia rims are usually 4x98mm, same as Fiat.

I'm pretty certain the LANCIA wheels I have (I don't know which model they came from) are 4x100mm....I'm also pretty certain they are hub centric wheels but I will verify all that when I put them on next week....

Lancia has mainly 3 different bolt patterns. 4x98, 5x98 and 5x108 (Stratos). Newer models might have different patterns, but any 4 bolt wheel from the 70's and 80's that are true Lancia wheels should be 4x98. If they are not, check the holes, they may have been enlarged incorrectly by a previous owner to fit the car. I seem to remember someone 7 or 8 years ago who took 4x100 wheels and redrilled the holes to fit the 4x98 pattern and they were no longer balanced or safe for any use.

which is 4x98.Recheck on them............Al

I might have to get longer bolts because the LANCIA wheels seem "thicker" than the stock Bertone aluminum wheels I had on before.

I also like the look of the LANCIA wheels better on the X....Those stock '87 wheels were pain in the a$$ to clean and they pit easily.

I have tried to install 100mm wire wheel tower by using wobble bolts, but I think the way is rather hard to centerize wheel on the car, then I use center rings between wheel and X, wire wheels fit my black X then.
