i used the hanger/alignment tool for 13 years now Mercedes p.n sorry don't have it.

as for the studs, they are not to be used for racing,(i know some of us do it anyway) the studs go all the way through as you know, if your rear studs are too long and go in too far they hit the emergency break cable. i do not use spacers or studs and yes it is a pain in the *** to install the wheels so i buy the almost drag radials tires for the street, they are std on 6 to 700 hp cars like bmw and mercedes that are very solff, and last about 40,000 miles.that way i don't have to change tires at the track any more.
look at https://www.crossfireforum.org/forum...-new-post.html you see i got a o.15 light and a 1.888 60' so yes they grip,, street tires and open rear. jim
