Tires
Looking for some recommendations please.
Have a 98 coupe and want to upgrade tires and wheels.
Really love the CCW SP16 or 505’s but CCW tells me current tires
need to be larger.
i am considering 305/35r19 for rears with 275/35r18 fronts. Would this set
up work for fitment and profile? Would this aesthetically look appropriate on
the car? What issues might I encounter with these tires? See some posts about
traction control, lowering the car, etc.—-
Everyone here is really helpful with their input and recommendations!
Thank you!!!!

I would suggest that you change the size of the fronts to 275/40-18. The delta in tire diameter between the 305/35-19 rear (27.4") and the 275/35-18 front (25.6") is 1.8". That would likely prevent Traction Control (TC) from ever kicking in if needed. The diameter of the 275/40-18 is 26.7" meaning the delta in diameter would be 0.7". The general rule of thumb for tire diameter selection for the C5 is that the rear tire diameter should be 0.5" to 1.5 " larger than the front tire diameter to avoid TC issues. Under 0.5" can cause TC to kick in when it is not wanted/needed. Over 1.5" can prevent TC from being activated if needed. Factory delta on the OEM tires was about 1"

Great advice from 8VETTE7!
Hope you'll post some pics once you have your tires/wheels swap completed.

Running 275/35R18 front 305/30R19 rear and have no TC issues/warning lights - fit nice a flush.
I went with Hankook VENTUS V12 EVO2
The ratio is 0.7" which is within norms and close to factory.
