I have owned two srt6s . The first was stock rode fine but very loud tire noise on the highway. Very stiff seats, my butt hurt.
Now I have a heavily modded srt with eibach springs and adjustible connis, and my butt is killing me after an hour of cruising. Also I think the seats are made for a Kentucky Derby jockey ( I am 5'8" 225 lbs.) Snug is a kind word. I think the seat foam is petrified to rock.
But I still love the thrust of this little roller skate.
