Wheel Offset Fitment Question

Wheel Offset Fitment Question
Hi,
I am getting some new wheels (Verde Axis V99) 20x9 +30mm front, 20x10.5 +45mm rear. I found someone running 275/35 on a 20x9 +35mm wheel with no issues. Can I do the same by adding a small spacer to add the +5mm or do spacers not do the same?
sorry for this question. I have never used spacers, so I am not sure what they due.
I was looking at getting 255/35 for the front, but when I saw someone doing a 275/35 on the front, I thought that would be nice since my old wheels were Steeda Spyders 20x9.5 +45mm and I ran the same 275/35 and like that size a lot.

A 9"/+30 wheel already puts the tire further out than a 9"/+35 wheel will, and you want to push it even further out??? What spacers do is effectively reduce a wheel's positive offset number, not increase it.
Both of those wheels are really the wrong offset for a 9" wide S197 wheel, and you should probably expect to get a stronger steering pull under hard braking when the RF and LF are not braking with equal effort (such as when ABS is working with a front tire lockup issue). Even 10.5" and 11" wide front wheels don't need offsets as low as +30.
Honestly, appearance reasons are about the poorest reason I can think of for using spacers. I'm not completely against the use of spacers - they're OK for solving very minor strut side clearance issues of, say, 2mm or less. But with 9"/+30 wheels you're going to have a huge amount of room behind the wheels and tires, probably well over an inch.

+30 is a good offset for the SN95 chassis.
The OE offsets for the S197 generally range between +45 and +50 for the 17" and 18" wheels. The 18" GT500 wheels were 9.5" wide with a +45 (I've also heard +43 but haven't been able to verify it personally).
The little 16" wheels that were available on the early years (that probably nobody is interested in anyway) were +39 but only 7" wide, for 215/65-16 tires. Yuck, barely acceptable as rental car fleet equipment.
At 10" wide (aftermarket only), +42 works at either end.
