Yes, the 5*120 is the BMW bolt pattern, also on the CT.
The Gallardos have 5*135 = Audi... About the Murci/Diablo I'm not sure, might be that they have still 5*120. What can be done is using pattern change plates.

Emery,
Espadas (from what I've been told by owners) and Urracos also run 5x120 w/ 0 offset, but you won't get a larger wheel that way :-) I believe the newer cars are also 5 x120 and as Raymond says (and I think we covered in your Jalpa 18" wheel thread) there are plenty of aftermarket wheels intended for BMWs that carry the same bolt pattern. For example, the Compomotive VT is a Bravo style wheel in 17 inches available in a variety of widths/offsets ... There were pics of a Jalpa a few weeks back (I believe in your ear;lier thread) w/ 17" VTs; personally I thought they looked great. Again as mentioned in the earlier thread what you need to be careful of is offset and width as well as rolling diameter and (IMO) the appearance of the car w/ ultra low profile tires. The Murci and Gallardo are 13" at the rear and run 18"/19" wheels w/ 35/30 aspect ratios. I think Laust was saying he wouldn't go much more than 10" at the rear (although w/ the rear fenders I would have expected a bit more), not sure what a 30 aspect ratio would look like? Comments any Jalpa owners? What can be run safely at the front and rears? How does that match w/ the newer Lambos?

Chad is dealing everything
BTW: do you know if the Diablo/Murci bolt pattern is still 5*120 like on the CT? I thought yes but I'm not sure.

Take a look at: https://www.rsracing.com/tech-wheel.html
(First reference I found in a Google search :-) ). For our cars, the 5 refers to the number of bolt holes and the 120 is 120mm, see the reference above to see how the measurement is made. 120mm is ~ 4.72 inches. The GM 5 bolt pattern (at least on the Corvette and I assume all reasonably recent GM cars) is 5 x 4.75 inches - so REAL close. I know an Espada owner who has been using GM wheels for several years w/ no problems. Sounds like you have been okay as well. I'll let the engineers on the forum tackle whether the difference has any real world significance ... personally, I would think if the hub mates up we're okay :-) For Emery's purposes it sounds like the Diablo bolt pattern is 5x120mm as expected.

I just had to look it up after my last post. This explains it all:
Lug Bolt Circle Calculator - http://www.skulte.com/boltcircle.html Actual Bolt Circle vs Measured Distance Center to Center of Opposite Stud 3.937" (100mm) vs 3.744" 4" (101.6mm) vs 3.804" 4.25" (108mm) vs 4.042" 4.409" (112mm) vs 4.193" 4.5" (114.3mm) vs 4.280" 4.528" (115mm) vs 4.306" 4.724" (120mm) vs 4.493" 4.75" (120.6mm) vs 4.518" 5" (127mm) vs 4.755" 5.118" (130mm) vs 4.868" 5.5" (139.7mm) vs 5.231" |

5 * 120mm is the common BMW bolt pattern, Chad has a burnt 25th with BMW wheels on it
