Hello everyone, so my allocation comes up next month, getting my order in asap. I've never sat in a c8 yet, im a larger guy, tall and weight wise. I was told the gt1 seats would best fit a larger occupant, i am going 1lt but I've been noticing 2lt have power side bolster adjustment on the gt1 seats Can anyone please post a video/first hand info on if this would be a must have for a bigger driver? Id rather not go 2lt but if its a big difference i just might. Thanks in advance

 

I have 2LT and the bottom bolsters by your hips don’t move. Just the side bolsters move.

 

The power side bolsters on the GT1 seats in the 2LT don't offer any more room when fully open than the fixed GT1 seats on the 1LT. They only get snugger. The thicker foam GT2 seats are even snugger in the 2LT, so if you're concerned about fit, I'd opt for the GT1 seats in either trim. Also, the GT2 seats are about $1500 more in the 2LT than the standard GT1 seats if you're trying to keep costs down.
