16" 150 barrel spring

[rakracing]

Billet,,, I've run the 400/200 stack a lot on my grt even used it with the lock ring at 0 travel, any idea how that compares to the 16" barrel spring on a rocket, tighter ,looser , in middle and off

To be honest anymore, I hate the LR spring. It's so driver or situation sensitive, you can't really give a general rule of thumb to it.

Case and point, I've softened/stiffened the LR spring on several drivers at different times and gotten different reactions a few months later, lol.

Just this last week one guy got a different reaction then he has in the past. Then on one of the other drivers I did the exact opposite as far as changing rate and he felt the same thing. Both got a tightening effect but from completely different directions on spring rates.

Personally, I ain't been a fan of the soft stuff for years now and typically don't recommend anything softer then a 225 for the most part. Not that is correct by any means, just seems like the stiffer stuff works better with my type of set-up or what ever.

Spring rate is spring rate so really don't matter whether it's a single spring or a stacked spring (assuming no stop nut or coil binding to change rate thru travel). Now granted some might be more linear then others.

For the most part, you will notice changes on entry or upon initial throttle and not so much off the corner with a LR spring change. However many will feel a change off corner, but you can argue that most of this comes from a change in the middle. Mess up the middle and most feel it all the way off the corner but most of the change IMO is from the middle handling changes.

Take that for what it's worth (nothing) and you get what you payed for that info, lol.

i know what you mean, also not a fan of lr softer setups, I preferred a 275 on the lr and 225 on rr worked best for me, we do think the same on entry and middle, keep it free or it screws up from the middle off. thanks

Thanks for clearing that up, billet! I did the same thing with the same driver but different car. He said it helped the drive on a Smack but hurt the drive on a blue Rocket. I chalked it up to a finicky driver! LOL

On stuff like this, sometimes it is best to listen to the stopwatch and tell the driver to get used to it. The LR spring by itself isn't what is creating the different feel in forward bite...just saying...

Tried it this past weekend. It seemed to tighten up entry and maybe the center just a little, but gained no forward bite over a std 200

That's what I would typically expect, like I said more times then not it's about entry and initial throttle. Entry change is usually the same for most, it's the middle where the confusion comes in. More often then not, the different changes (tighten or loosen) to the middle is directly related to the change in entry, IMO.

175 l.r. on slick to tighten entry and soften throttle as not to spin as easy on real slick..????.. or 175 l.r. and 250 r.r. with traction to stay on gas with more side bite less spin off corner for momentum..????..windy..~V~..
