Wheelie leads me to get Front end limiters

This past weekend I did a wheelie
A little too much for me

So me and a couple buddies made some front end limiters to prevent the front end extending too much
Hopefully this tames the wheelies down

Luckily, not really any big damage.

Had to buy some new rubber bumpers for the top of the control arm, as they got flattened.
I have 28" tall front tires , so that helped too

Yep, that'll do it. I had the same problem. 60ft times were better once I got them in.

I am jealous of your wheelie. makes for a great photo, but hard on parts and expensive.

I have always not-comprehended how a front end limiter works. I know it limits how far the front suspension can hang, but how does that limit how far the wheelie goes up?

Basically it limits the "sprung" travel going up.

I have lots of travel because I cut a coil out of the front Moroso spring
My front is pretty low

So say instead of the spring going up 7", now it'll only go up 5".

I just fear now that I gotta find the sweet spot with the limiters, otherwise it's not going to weight transfer, and spin instead

You know how a truck climbing a hill gets easier and easier to flip over backwards as the hills gets steeper and steeper? Same concept.

The higher the nose, the further back is the center of gravity, and the less torque it takes to rotate the vehicle around the rear tires. His long travel springs were helping to throw the nose up to a high angle (CG further back) before all the weight was on the rear tires. Takes less torque to continue to rotate the vehicle to pick the wheels off the ground.

Shorter spring travel makes the front tires unweight earlier in rotation when the vehicle CG is further forward. Takes more torque to continue to rotate the vehicle up in the air. Basically he's using the weight of the vehicle to keep the nose down.

ah-ha! ok, I can visualize it much better now, thanks guys. longer springs helped launch the vehicle up higher, and shorter (shortened via limiters) take away the full "spring" of the spring.

Re: Wheelie leads me to get Front end limiters

Update with the front limiters .

Definitely they helped!
Had to do a couple adjustments

Went a best 60ft of 1.28
Went 5.72@118.9 in the 1/8th


Next is to get double adjustable struts!
