both great choices.....
On any wheel, I prefer a smooth transition at the hub.

 

I agree with the smooth transition at the hub. It makes for a cleaner looking wheel.
I was planning on getting the GT30's but since I want custom colors it'll be a hassle and cost $600-$700 over the price of the wheels. Plus they're 2 piece wheels and have a cast wheel face.

I figure the DPE ST7's have the same basic look plus I can get them in customized colors for the same price as the GT30's without any customization.
Plus they're 3 piece fully forged wheels so that's another benefit.

 

the ST7 would be my choice over the GT30 They are a great looking wheel.

 

Good to hear
Now to set aside some cash for my wheel fund...
