Hey man, if you use R32 shocks i recommend using taller bump stops so the tyres don't rub on the shock while under compression due to the increased camber. I did this to use 215/R17, I also used R33 front springs on the 32 shocks as the 33 springs are slightly stiffer.
Even the power of the old L20et with a few mods (more boost and intercooler) will cause it to sit on the bumpstops while boosting if on standard r32 shocks, so forget passengers (if you like boosting), all of this depends on tyre size and offset though.
Ive had to find all this out through trial and error so I've learnt a few things about them along the way i.e. r33 viscous diff fits in the r30 housing with slight mods and s13 hubs fit also with slight mods but you cant use s13 shocks due to our small strut tower so adjustables is the only way to use them etc etc,
PM me if want to bounce ideas as i may have tried it and failed already,might save you some time/frustration.
