Solid Bushings... Custom only?
I am thinking of a solid bushings on wishbone / anti-roll bar etc... since I am having wheel hopping when trying to do a burnout.
Is there any aftermarket parts for the first generation yaris? What are your thoughts? |

1. What motor mounts/trans mount are you using now?
2. Are you using a torque damper? 3. What is your suspension and how do you set it up for drag racing?

Are your struts/shocks adjustable? What settings have you tried?
I would open up that damper, take out the rubber rings, and fill that with urethane like some people do on the trans mount. That will help a lot. (but it won't be adjustable)

I will check on the damper thanks for the heads up... What about the wishbone bushings? I am thinking of removing rubber bushes and make them solid screw type fitting instead plus bracing |

Stiffen up the sturts/coilovers rebound/compression
Having one solid mount, especially one that strong, while having the others stock isn't a good place to be. Stiffen up the others by at least filling them with urethane. Solid Delrin or Nylon ones would be custom I'm sure. If you want to go completely solid (steel), you MUST replace all at the same time. Think about what will happen if you don't. Also, I found that sometimes I do get wheel hop and sometimes I don't. I haven't figure out exactly how to get around it though, but I'm leaning towards that the clutch needs to get popped from a high RPM - don't know if this is actually true though.

You are using slicks right? What's your pressure? I get no wheel hop at all, and I am not using solid mounts.
I set my suspension soft in front, full hard in the rear. Lift in front is ok on launch, the stiff rear causes the front to come back down and bite.

I've heard of superpro, don't know how good they are.
Whiteline makes caster bushings for the Echo, I gotta scheme some way of getting them in for next year (if I don't make my own LCA's). Double adjustable struts/dampers would be the key, but lowering your front spring rate should also help a bit. For all out drag racing, the front spring rate should be (relatively) low anyhow.

I would try filling your other two front mount first before changing all those bushings.
My motor thrashes HARD if the wheels spin at all, but I know the stock mounts are stupid soft. |

This could be your problem...
If we get wheel hop under acceleration we look for one of two things. If the wheel hop is bad, like it feels as if the tires are bouncing off the ground, that usually indicates a blown shock - it cant control the spring so it hops the tires. If it is more like chatter, the tire is trying to hook but just cant bite, that usually means to much compression damping. The downside to coil-overs that change rebound and compression simultaneously is that by the time you have adequate rebound control, you typically have excessive compression damping. If you know the shocks are still good, try softening the front damping.

What's a semi-slick? Drag radial?

probably like 100 treadwear tires, like R888.. not slicks per se, but such low treadwear that have tread, its not save to drive on the wet roads

A tire with a soft sidewall should help too - R888's don't count lol

Your tire pressure is too low. Radial tires sidewalls are hard not soft like slicks. The wheel hop is due to the sidewall not supporting the tire enough.
