Thanks but no thanks. That post doesnt explain ****. When we went to the track Steve with his brand new 2k2 had wheel hop also. Anyone else has an answer. Thank you.

 

What springs are on your car? Looks very low, or is that just photoshop?

 

can u be more specific when u say wheelhop???

 

Its because we have FWD cars with soft rubber bushings and a relatively torquey motor. FWD is already at a disadvantage. The weight transfer, and because the front wheels steer, brake and accelerate the car as well as hold most of the of weight is another reason. This is because of all the play needed to accomodate all these functions. Wheel hop is when the tires are on the verge of hooking up and breaking loose, so its that happy median.

One solution would be radial arms, http://hybrid.honda-perf.org/tech/z10.html but nobody makes them for us (yet). Other solutions include polyurethane motor mounts and control arm bushings, as well as a lowered/stiff/damped suspension.

 

The answer is there if you're willing to accept it. The engine mounts made by Place Racing will eliminate 98% of wheel-hop. If that's your problem, that's your solution.

 

The only problem is your car starts to vibrate!

 

What about them makse your car vibrate?

The engine mounts serve two purposes:

1) They hold the engine/tranny firmly in place
2) They insulate the rest of the car from engine vibrations.

Once you realize that these two goals are in direct opposition to one another, you then understand that when you use a denser (firmer) insulating material in the mount (Say polyurethane, instead of the OEM rubber), this holds the engine/tranny in place better, but at the expense of transmitting a bit more engine/tranny vibration to the rest of the car. . .

The OE engine mounts are a compromise, designed to address both of these needs as equally as possible. If the wheel hop bothers you that much, get the P.R. mounts, but be prepared for more vibration in the cabin.

 

Thank you!

 

When I installed Koni shocks on the front, almost all of my wheel hop went away. It's not a problem anymore. Soft struts allow the wheel to oscillate up+down too easily, which is what wheel hop is.

Get better front struts and I think the problem will go away. Tokico blues suck.

 

That makes sence. How firm do you keep your Koni's set for?

I agree - good idea: the strut/shock upgrade. Hadn't thought of that. It would be a smart way to address this problem, because it's an upgrade you'd want to do anyway, for all the right reasons.

If you're shopping now though, go w/ the KYB AGX. Koni's are great, but AGX is the new king of the jungle for less $, (plus, no mods required for install).

 

I have my front Konis set for 3 half turns out of 5 maximum. That seems to be the best comfort vs performance compromise. At 4, handling was sharper but the ride was definitely choppier/harsher. Still not terrible, but too much over time for me. I have H&R springs, BTW. The Konis (all around) plus H&Rs handle really well but are still reasonably comfortable with my Koni settings.

 

i never had wheel hop before.....

 

If your car does have "three pedals," & you've never had wheel-hop, it's 'cause you're not launching hard enough!



(It really only happens* when your doing a drag-style launch with a healthy amount of feathering of the clutch). It's accompanied by a violent amount of vibration - the dashboard pretty much sounds like it's going to shake apart into a million pieces - there's no mistaking it).

*On a "lightly" modded Max. S/C & Nitrous vehicles can have wheel-hop under hard accelleration if not equipped w/ the right struts or P.R. engine mounts (because of all the extra torque being transmitted to the engine mounts).

 

Thank you guys. I will ge getting new shocks/springs soon.

 

Well..... I got new shocks/springs and still have massive wheel hop.

There were 2 bimmers around me and I tied to race them but got wheel hop all though 1st gear. I should of let go but I was sooo stupid to continue flooring it.

How bad is wheel hop for the car because I hope it wont harm it by accidently happening few times. I felt so bad for it.

Are place racing engine mounts that harsh to ride on?

 

Excessive wheelhop will destroy engine/tranny mounts and tranny cases if its bad enough. All you can do is get/make stiffer engine mounts, the increas in vibration isn't much.
