Bump stops

[Matt49]

Is there a point where a softer spring should end up creating more drive? Assuming it allows the car to get into the bump harder?

Kinda. But you have to be able to keep it there. As soon as you unload off the bump, your dynamic wedge falls off a cliff. And to billet's point, that's where "forward bite" is coming from.

In that sense couldn't you tie the corner down harder with rebound to keep it from coming off

Or just remove a bunch of cross, so spring doesn't try to hold the car up.

Lots of ways to skin the cat.

Just need to end up with the correct balance of traction to minimize time for the 360 degree turn that is 1 lap.
Thhen repeat until you see checkers. Lol

say its a 5 lb spring with your bump, just because its laid over and looks cool doesnt make drive. youll hit that small bump so fast itll sheer traction on that small tire

it has a lot to do with left rear bar angles , the thrust load against that bump stop will keep drive in the left rear , the trick for me when i started with the bump was to get just enough dynamic rear steer to stay just below a throttle push , or the sweet spot , it was amazing what moving the upper bar up one hole did........

Watching the touring guys it appears that all of them are basically on the verge of a throttle push when they launch really hard off the corner. Especially if they happen to under-rotate the entry. Of course they are very good at driving around that (so to speak) without lighting the rear tires up...probably one of the most common driving mistakes that cost you on the stop watch.
