Found there way on to the X over the weekend. After waiting literally weeks trying to get the Toyo R1's in 195/55/14 rear, I gave up and got a set of the R1's in 195/45/14 front and rear. It turns out the 195/55's have been on back order from Toyo for the past 3 months! I still have a set on order for the rear, who knows when they will deliver. I have a set of 6.5x14 Biturbo wheels for these wheels when they arrive (they go on the rear). In the mean time.

The 195/45/14 R1's on Maserati Bi-Turbo 6x14 are a nice improvement over the 185/60/13 Sumi's on 5x13 "phone dial" X wheels. The combo is lower weight too which is always a plus. The stock spacer was removed and the Biturbo wheels have a ET of 6 which results in an effective ET of ~12. The stock phone dial wheel bolts were too short ( Biturbo wheel centers are thicker) and M12 x 1.25mm stud conversions were used in place of the bolts.

I put almost 200 miles on them over the weekend, much improved grip (not surprising) lighter and more responsive steering to boot. Surprisingly, the ride is pretty good too given these are 45 series tires. No clearance problems with this wheel & tire combo.

Now the fun of tweaking the suspension begins..

they look pretty sharp, just subtle enough!

I have some 6x14 rims that I have been meaning to do something with for many years now.

What kind of studds did you convert to? threaded on both ends or a press in? I have been looking for a looong press - might you have a part number ?

currently on the car are mad by Gorilla wheel accessories. They are M12 x 1.2mmm, 1.75" long. But the nut engagement is only 1D (about 12mm) which IMO, it not quite enough. They hold 60 ft/lb of torque just fine, but I paranoid of these having a problem. So, I got some 2.5" long ones from:

On the way.

The nuts are after market M12 x 1.25mm, 12 point drive with a 60 degree seat from an evil-bay seller. Don't remember the brand at the moment.

Biturbo wheels should not be difficult to locate. It was not difficult to find the 3 sets I have and they are not very expensive for what they are. Figure about $300 per set of nice ones. They do show up on evil bay every so often too.

The earlier Biturbo wheels that are solid silver are 6x14 and the later BiTurbo E wheels with the gray center and machined rim are 6.5x14. Later BiTurbo and Chrysler Maserati (uggg) have a 5 hole bolt pattern which is not compatible.
