LS6 Sonoma Driving at High Speed, On Track Action! | Grattan Raceway duel with 1972 Cutlass

If you’ve been following along the last few weeks, I mentioned something special was brewing for trackday this year! Aside from being the first time the LS6noma has had towing duty in a good 5-6 years, we also got it on the track to shake it down! Then the arch nemesis 1972 Cutlass comes along and we duel it out for a couple laps.
Pleasantly surprised at how she handled but she needs a little bit of work, thanks for coming along for the ride!

I bet if you had a seat that held you in tighter and stiffer suspension you could really find the limit of that truck. Overall though man, you gave it hell and had fun doing it!

[@AdamPE21]

Thanks! Yeah man it was a blast! Going to roll the fender lips up front and stiffen up front springs at least and look into a seat that’s got some bolstering to it. Though the ride is nice and cushy in the OE seat, but sometimes a sacrifice is necessary for speed!!

[@JunkRacecars]

Fuckin mint! What made you say it's easier to drive than your E21? Is it just more compliant and forgiving?

[@AdamPE21]

Yes, a lot more comfortable but definitely not as quick. It makes me realize I have to do something about the brakes on the E21 to make it more responsive!
