What causes Hike in the rear?? and other questions...

Why would you run a bumpstop? Why not use the benefit of it sitting down even lower to your advantage and raise the deck height even more?

To a point, that's true. Eventually, you may get too low.

Say I have the car as low as it could possibly go and can't go any lower, but it has too much extended load for what I want. The bump would allow me to keep ride there but I could unwind the coilover nut and shim the bump and have less extended but same ride

Hope that makes sense

thats why they have a min rule also now, I've seen cars dragging the frame rail under the driver, its easy to fix and tech, 3-4 in wheel to slide under the driver at ride height, then jack her up and check the deck height, but watch whats next, watch how far they get the nose down now to get the angle back, lol, there already working there butts off on it, get ready for a new chassis lmao

this is how im thinking as well , also with the ride height rules starting to appear , i guess it would help meet this with a light spring and still allow more control of load at droop....

All makes sense now. I hadn't thought of it like that.

yep , every one thinks of a bump stop in the dynamic state , and MBR , that tornado and bump stop was a little over 100 bucks , a complete stacked set is heavier and cost at least double that amount , i am in agreement on the stacked being better or lets say more adjustable , but if you dont think outside the box and try things , you will fall behind....

Is there any consequence to going too soft on the left rear spring, while using a bump to maintain ride height?

I already have stack hardware and a 50# birdcage. Im not buying a tornado. I'll buy things if the physics make sense. I never bought a strange oval axle either.

A hard landing may break your shock mount off, but otherwise no. I've done it before.

[CCHIEF]

The main reason to use a single spring is because you rules specify only one spring per wheel...but, just because there is a spring there doesn't mean it is functional, all I'm sayin', for you limiting rule racers. -Wink

The reason I ask about the light spring is I have been running a 50 on the lr this past year but have not been sitting on a bump, so my chain load is very high. I have also been fighting a terrible bounce on throttle all year since going to this spring.

I'm guessing you have a spring or very soft rubber on your chain?

[bcarrot28]

I have tried several hard, soft and none. Still violent bouncing

Might be a geometry issue then. How high is your chain load?

[bcarrot28]

My car is around 200lbs. Teammates car is on the same effective spring rate but stack. His has been as low as 40 and still bouncing.
