what are the oem offsets and what are people using to get a flusher look? is front et30 and rear et50 to aggressive?

 

OEM
19 x 10 +43mm
20 x 12 +59mm

Many aftermarket manufacturers, including Forgestar below, which look perfect IMO
19 x 10 +30mm
20 x 12 +50mm

thanks for the info. I have a z07 car and tried to lower it without much success. raised the rear bolts all the way to the leaf spring drove the car 40 miles and got a whopping 1/8" drop!! thought it would go at least 3/4" but no dice. for now I ordered the 30/50 offsets hoping it doesn't rub. these are custom made wheels so I cant return them

 

30/50 will be fine....as long as you stick with stock tire sizes.

 

decided the 30/50 was just to aggressive for my taste so end up ordering a 35/55 setup in 19/20 running oem Conti extreme rubber. about 5 weeks for there build with a few nice subtle touches

 

FYI, the Continental tires have a much more rounded shoulder (sidewall) than the Michelins, and will give you more room than you might be expecting.

 

I’m running stock size Continental Extreme Contact Sport 02 tires on stock sized wheels with 30ET front and 45ET rear on nonZo7 package car. It’s dropped all the way down with stock bolts. No rubbing or any issues whatsoever. The 45ET rear make the wheels more concave and fill the wheel wells perfectly.

 

You’re not going to rub, I risked it and went 45ET in the rear and they perfectly. 50ET is a safe conservative recommendation from most wheel suppliers.

 

just hard to tell with the pic angles. looking at the forgestar pics its to aggressive for my tastes. I know everyone has different ideas as to what is too much but with the amount of $$ it costs to have custom forged wheels made im going to error on the side of caution. the oem offsets would be fine with me if I could get the car lower but mine isnt having any part of it. lowered as far as the bolts will go netted me 1/8" drop. not even worth the time it took to do it

 

Mine dropped a lot as my car is a non Zo7 package car. I’ll take pics from better angles so you can get a better idea.

 

Nice. What wheels and size are you running?

 

Here are some better pics
