Lorinser RS 90

Hey Mark, good to meet you yesterday ...loved your black SEC. If you found some Lorinsers that are 17x8 et 22 then it's a good bet they are RS90's. That's what I had on my SEC at the meet (the faded, peeling silver blue metalic 500 SEC with the AMG wing on the back). I have 17x8 and 17x8 1/2 staggered with 245/45/17 front and 255/40/17 back with 1.5 inch lowered with no problems. I had been running 275/40/17 on the back but changed it when I dropped it.

If the wheels you are looking at are the one's in the pic, they are RS 90's

Cheers,
Greg

That tire size that is mounted on the rims is going to screw up your spedo...wrong size to keep everything good without recalibrating the spedo.
