I have a 1992 SC300. Will 20" staggered wheels fit, with out any modifications?
The front wheels are 20x8.5 with a 35 offset, and the rear wheels are 20x10 with a 38 offset.
I'm also thinking of adding an offset of 5mm spacers to both the front and back. Are the spacers even needed?

 

You probably need to roll the fenders. Is it stock susp?

 

up front you should be fine at stock height and lowered, depending on how low you want to go. the rear you will need a roll, probably a good roll if you went any lower than stock. i shaved with 20x10 42 offset and im cranked all the way down on some tein basics. not a severe drop but its enough for twenties. i have the same size and offset up front. before lowering there was slight rub at full turn and a good turn and braking or up hill turn or something with fenderlining. dropped all the way down up front with no front lining i have no rubbing issues unless turning on a bump or incline decline. thats just slight rubbing. i believe a 30 series up front would solve both heights rubbing. maybe even a light narrower tire also. my tires front 245 35 20 rear 275 30 20. i hope this helps.
