How do you mean alignment? The increased track of the conversion? 10-15mm is good I find as the 1200 seems to tramline badly in road grooves from modern cars and soft tar/ashphlet.

I don't get how it handles badly? It might be simple case of spring and shock upgrade needed. Any pics of current set up?

You running 120y or larger front sway bar?

I like my front now (240z konis and 250lb coil over springs- could use slightly softer at 225lb but they were cheap 2nd hand and new) but need to work on rear. New shocks should help.

Describe what you don't like bout it and we can make suggestions. Your brakes should be good- similar to s13 in performance
