new 2 me 90q, questions

["Todd Candey" <tcandey@usr.com>]

     Hi again, while I've been dealing with the ins co's on the damage to 
     my 85 4ksq, I went and bought an 89 90q.
     It's pearl with gray leather, 14" BBS rims and has 40k miles.
     This car is perfect in every (factory) way.
     The questions I have are related to the suspension and the brakes and 
     wheel/tire combos.
     
     Has anybody out ther done any suspension upgrades? What about 
     wheel/tire upgrades, what's the "hot set-up" is it possible to go 
     something like 16x7 with 215 50 16? or perhaps larger?
     
     Also, I know that the girling g60 calipers and the larger rotors from 
     the ur-q are a bolt on, provided you have the carrier. But what affect 
     could that have on the ABS?
     
     Thanks,
