X2 on the swaybar.
At the last minute, I put mine back on - mostly to make the drive out there bearable. Then forgot to take it off.
I'm glad I did. I didn't reallt crank it down tight, just enough to prevent serious sway. I didn't seem to have any problems w/ sway or tippiness, and the ride wasn't bad.
Now, again, I also was holding back a little in anticiaption of a second run, and only posted high 9s... so may not have been pushing it like others did.
Re: HP, I just don't see "high HP" being a big deal. Low/super underpowered, like a built up Sammy on stock 1.3... or heavy Toy on 35s w/ stock 22r... yes, that's a problem. But a stock 4.0 should be fine. In this course, there's just not that much open space to really speed up.
Oh and an Auto Tranny is nice for this b/c you only have to worry about 2 pedals - but be sure the lines are well protected, lol... a 5spd won't leave you stranded...
