I don't remember when they started doing this, but my front tires skip really bad in first gear under full throttle. And when they do this, the whole car shakes like it's falling apart. I thought getting wider and newer tires will help, but it didn't. I hope you know what I mean by the tires skipping...the tires don't spin, but they get traction and lose traction and repeat very quickly. It only happens in 1st gear and a soon as I shift to 2nd it's fine.
A friend of my told me that I have too much torque, but I doubt it becasue I don't have forced induction. My modes are OSCAI, Y + B pipes, UDP, and Cat, a very common setup.
Could this be because they didn't fix my car right after the accident? I hit a curb really bad two years ago and they had to replace the right driveshaft, the control arm, maybe also the struct assembly and other related stuffs. I have my tire pressure set at 36psi, is that too much? Any help is greatly appreciated! Thanks.

It's called wheel hop. Check your motor mounts and suspension components. Might have worn out lower control arm bushings. Upgrade them to the urathane bushings and A LOT of that will go away.

 

Thanks. Are you talking about the Polyurethane Motor Mounts that Cattman is selling?

 

hey you got mad at me in the other post because i asked you if you have a 5spd.. now.. the reason i asked you this was because this weekend my tires were skipping because my clutch was slipping.. please next time find out where i am going with the question before you start to get defensive..

and yes.. i DO know how to drive a 5spd

 

No I didn't get mad...I was J/K...all I was trying to say was that I don't think it's a 5spd thing...but maybe I'm wrong. Maybe I launch to hard. Sorry that I got you offended. But don't get mad on me now...help me with my problem, Thanks!

 

Another question I have is that what pressure should we have for 235/45R17 tires? The stock recommended 32 front/29 back?

 

Yea I have the same tires and I just got the ACT Clutch installed and I didn't get it broken in till I got new tires and wheels, mad wheel hop when I tried to grab second really well, and it even in 3rd gear it will hop

 

no problem man.. we cool..

well as i said before.. i heated up my pressure plate real nice this weekend.. doing burn outs and NOS launches.. and then for the rest of the day .. every time i would shift to second gear.. the tires skipped.. freaked me out.. it did it again in 3rd too.. but it turned out to be my clutch.. it hasn't done is since.. but the reason i knew it was the clutch .. was because when i got out the car.. i could smell the clutch

 

It might be if your tires are worn out. My old Kuhmo Z's would hop when they were near the end of their life, but now my new Michelins just spin....much better.

 

Really that's because the Kumhos have so much grip they hop, thats why my new ones are hopping like hell

 

Wouldnt the grip keep them on the ground though? Not cause more hopping?

they have more grab so they don't sping the bounce because of the pressure, if they don't grab as good they spin

 

That's what I thought, and that's why I got new set of tires...but even the new tires are hopping like hell.

It seems like many of you have the same problem...how many of you plan to get the PR Engine Mounts? And for those who have them, will by just installing them along really solve the problem?

 

Well I'd rather it not feel like my car is about to fall apart upon takeoff......just my preference.

 

I agree with this, not because I own UHP tires, but if you just think about lightly dragging a soft, brand-new pink eraser across a table, it will hop and skip along the desk as it grips and slips. On the other hand, take an old, hard, and crusty pink eraser and drag it lightly across the table, it will glide smoothly because it's slippery.

I think the 2 greatest factors of (straightline) grip in tires are contact patch and rubber compound. Maybe those Michelins have just a bit less of one of those?

 

When I had brand new goodyear all season tires on wet roads, they would skip like a ****. But now after a few thousand miles, they just spin at wot on wet roads. It's all about the tires man. I highly doubt that it's anything mechanical in your car. Perhaps getting stiffer suspension will help because they will push the tires harder to the ground giving your better traction. These are just my opinions of course

 

No, they are brand spanking new. And they will hop when I am really layin' a wheel, like if I drop the clutch....it's just that the old Kuhmo's would cause wheel hop every time, like when pulling out of a parking lot quickly..every time the tires would spin it would hop.....that was very annoying...these are much better...

 

So nobody knows if the PR Polyurethane Engine Mounts would help?

 

Poly's might help. I've seen devices that mingle with the front suspension on FWD cars to reduce wheelhop, but come on. You've got a V6 fwd sedan, manual, that produces a good amount of torque. What do you expect? You've got to work around it, by not just all-out flooring it in first/dropping it from high all the time. This isn't an integra that needs to be dropped from 3,5-4k for a good launch...

As far as tires go, ever notice how when you dump the clutch and the tires are wet, the wheel hop is all but gone? My guess then is that if you don't have wheel hop either when you drop the clutch from high or when you suddendly WOT in 1st starting from about 2k+ RPMs (esp on inclines), then your tires don't grip that well. I imagine if you had some slicks for the track, if you warmed them up nice, you may be able to spin & grip those with minimal hop issues. But not well-gripping street tires.


The best way to get rid of front-end wheel hop and fwd handling limitations in one stop is to buy a RWD

 

I am almost certain that most of you experiencing wheel hop are running 17"+ rims, right? Low profile tires are more prone to wheelhop due to their wide and thin contact patch. Lower profile tires are also harder to launch with.

Regardless if you're running stock or larger rims, "dumping" the clutch is a no no. Dumping the clutch almost always results in wheelspin, bog, or wheelhop. Wheelhop is very bad for the car and can lead to broken engine mounts, broken differentials, bad bearings, broken half shafts, etc. The right way to launch a high torque FWD car is to slip the clutch just a little to get rolling. Once you're rolling, quickly release the clutch, but don't dump it. If you feel the hop, let off right away.

True, but how does the stock 2K2 max deal with it? It's got more torque then our modded 4th gens. What is it that it has and we don't? I haven't heard anybody with a 5th gen complaining about wheel hops. If the 5th gens with over 247 ft-lbs of torque can do without wheel hops, we can too.

The funny thing is that I never used to have any wheel hopping problems like this before when I first modded my car, the problem didn't exist until about 1 year ago, and I have the same mods that I had before. Now I get wheel hops if I floor it in 1st, not from droping the clutch at high RPMs, the tires would just spin instead. What's bothering me is that it never used to do that until a year later. That's why I think maybe something in the suspension or the mounts is worn out...
