Why does my classic have sooo much wheel hop???I have the full ES bushing kit and i have ST bars and AGX/GC 350f/250r, full ES motor mounts...I still have bad wheel hop, is this caused by my 17's?????Thanks for the help in advance

With all of those "anti-wheel hop" mods, I find that strange. Try putting on the stock 14" rims and see if thats your problem.

It's the weight you lost when you shaved your handles.:p :confused:

lower the pressure of your front tires. i'm sure that will solve ur problem

do you have the control arm bushings? that pretty much eliminated my wheel hop

Khiem

The tires you are using is one of the problem also

Try different tires and launch little higher

doesnt matter what tires he is using, whether it be street tires, slicks, drag radials. wheel hop is excessive play in the suspension. Your car looks pretty slammed in the pic. Try raising it to the point where there is tension on the spring in the strut assembly. See, when u slam your car, since the is no tension on the strut assembly and when u launch your car, the wheel bounces up and down.

Are your tires balanced?Do you have hubcentric rings on your 17's? What setting are your front struts on?

tires were just rebalanced and no i do have them rings....The struts are on setting 3....and the rear are on 6

Listen to SHOE
wheel hop occurs when the WHEEL HOPS up and down due to lack of consistant and sufficiant weight from the body distributed by the suspension to the tire for traction. You get a SLIP GRAB SLIP GRAB effect. Changing the tires may change the ammount of wheel hop a bit, but you need to solve the problem at its source---> the suspension:)

wheel hop is a dentits worst nightmare

I disagree. Yes, wheelhop is suspension related, but it can be solved by using different tires. Tires do matter when it comes to wheelhop. Try different ones. Less aggressive all-seasons and slicks have been known to do the trick for myself and others as well.

of course different tires are gonna have a different degree of wheel hop...thats because some tires have more grip than others. You get it? Sticky tires are gonna grab and release more violently than hard compound tires.

"the foot bone is connected to the...leg bone..."

use this theory. figure the problem from the source. start from the ground-tire section, then work your way to the driver.

When at the track I usually have a notepad with me separted into columns for all the variables i can change when I launch to get a better launch. I have found that reduced wheelhop happens with a lower tire pressure. launch on about 21 psi on street tires on 15's.

I also have the GC/AGX combo and I set them at all the way stiff on all 4 corners. Launch RPM is also important. The higher RPM you launch at the less likely you will get wheelhop.

What you need to find is the RPM where you just chrip the tires slightly and the car lunges forward. Too high an RPM and you will sit and spin (duh).
Anyway what I mean to say is you have to be methodical and eliminate things one by one.

Well, you're preaching to the choir here, but what I don't get is why you first say that tires don't matter, then you say this.

Another thing to keep in mind is that different tires have different sidewall stiffnesses. The stiffer the sidewall, the more prone to wheelhop a tire is.

Anway, there's no need to argue. I think we all agree that tires do matter.

pearl2000 - the tires are not the source of the problem. the source of wheel hop is the suspension. i am saying that since his car is slammed, there is no tension on the spring and strut so the wheel has an opportunity to bounce up and down

dan_93ser - when i said "doesnt matter what tires he is using", i meant different tires are only gonna alter(not eliminate) the amount of wheel hop because they have. Different tires have different degrees of traction, therefore different degrees of wheel hop, therefore tires are not the source of the problem, therefore it "doesnt matter what tires he is using". Its obvious that a tire with more traction will have more wheel hop because the tires is wanting to grab the pavement more aggresively than crappy tires, however the play in the suspension is causing it to bounce and taking load off the tires and suspension at the same time, causing the tire to release. the grab and release is wheel hop. no matter what the tire he is using, it will only alter the degree of wheel hop. some tires may have very little traction, almost eliminating wheelhop, but who wants a tire with no traction? The bottom line is, the suspension is the problem with the wheel hop.

i know it seems obvious to change the tires because the tires are grabbing and releasing, but that is not the problem. the reason the tires are grabbing and releasing is because the suspension is bouncing up and down. to stop that grabbing and releasing, you gotta quit the bouncing up and down. i hope that elaborates on the subject.

I concur with Shoe.

There's nothing to stop the car from coming up and off the springs with a coil over set up. Being that slammed it comes up and then bounces all over the place. There is no preload on the springs! I HAD a GC kit. I know.

Just for kicks raise the car up 2-3" (the adjuster should be 1/4" from the top of the strut with an 8" spring) and see if the hop goes away. It's cheaper than new tires.

Cheers,
Charlie :)

thanks charlie

nismo91ser - it doesnt hurt to raise your car for a day. give it a try and im pretty sure you will have your problem solved

I typed in "traction bars" in the search and found what I was looking for. I plan to do this mod when I get a classic. Read up on it Nismo91ser, it looks very affordable and eliminates wheelhop. Have I mentioned that your car is fucking bad ass? I'd love to find a black classic. What body kit do you have on there? I like the looks of it. Got any pics that show the side skirts better? Anyways, read this thread.
