Wheel Hop
 

Is anyone experiencing wheel hop under very brisk acceleration? Has this been a problem with the 350zs and 370zs?

Only time I noticed it was at the track when launching the car. Couldn't get the damn thing to not wheel hop. Then again the Vegas speedway isn't known for having good track prep. On the street with "brisk acceleration" I get mild tire spin (doesn't make a noise at all, just feel the slip).

No problem here. Do you have the LSD rear? Oh yeah, I see by your sig that you do.

What revs are you running when you drop the clutch?

I get noise and slip, but no marks.

RARELY I'll get marks, like 1 out of however many times I've done it...lol

Let the clutch out at about 3500

Kind of hard to do that without a clutch.

See, I can't get my rear to make the infamous tire squeal unless on slippery cement. On nml back top it won't squeal; it either slips with brisk acceleration and if I try to launch it hard it will wheel hop (though not nearly as bad as at the track). The funny thing is that it's the same with our 2000 T/A V8 and our C6 Vette. Yet with my 280z I can squeal all day long if I want. Both my 280z and 370z have limited slips. Oh well, no noise means less attention.

I look at it this way... my old 911 wheel hopped, my crappy late 70s Z28 spun the tires like mad.

I can live with wheel hop;)

The 350Z and Infiniti's have a wheel hop problem as well when they break traction. The key is to not let wheel spin get out of control.

This is the technique I use at auto-x.

Hold revs at around 3500
Drop clutch
Feather throttle at between 50-75% such that the revs stay between 3-4.5K until you feel the rear hook up.
Floor it!

If the revs get too high while you don't have traction you'll just get monster wheel hop.

4000 to 4500 rpm's will work wonders...........................
:tiphat:

If the tires are cold, they spin without noise. Get them heated up a bit and drop the clutch at 3500 = squeal.

I get wheel hop fairly regularly when pulling out of my drive on cool mornings. It's not really a "problem" more so a compromise you make when having an independent rear suspension and higher HP.

I've experienced wheel hop in my 350z and a little bit in the 370z. It only seems to happen when I don't give it enough gas, somewhere in that grey area between bogging and spinning the wheels. Sometimes it happens launching at the track, NOT a good feeling.

SPL makes a diff bushing set for the 350z, and according to them the kit also works on the 370z.

I had wheel hop on the 1/4 track in Montgomery. We will take care of that soon.

Let us know how you do it.

im getting wheel hop bad when trying to launch the z without wanting to spin tires, im not dropping the clutch either, maybe its because the tires are really cold, or do the stock bridgestones just suck? if i even accelerate hard in 2nd at 30 mph i still spin also wth? i also wanna see if i can drop the clutch and get it to spin from a standstill later without having any wheel hop but it seems like thats impossible. yeah i know lol i want it to spin when im just messin around but i dont want it to spin when i wanna launch,, hmm any pointers on both? hope this all made sense.

I have no problem spinning the wheels from a standstill. Just rev it up real high and dump the clutch - I do that before every run at Englishtown to clean off the tires.

hey all,

I had a 2006 mustang gt previous to my 2009 370 and it also suffered from wheel hop, but not NEARLY as bad. the Z is hop-happy, any loss of traction results in the shuttering. when i took my z to the track with my friend and his 2006 mustang gt, he pulled away hard on the launch..while he was getting solid traction, i was wheel hopping bad. He said that lower control arms were an instant fix and a smart purchase for his mustang, which has the same limited slip set up. I think the car would really wake up off the line with this purchase but i didn't wanna be the guinea pig :driving:

Stiffer rear springs help to reduce the wheel hop, but will reduce your performance off the line at the strip.

The 2005-2009 Mustangs had a problem with the upper rear link, it was too short especially if the car was lowered at all. There are several aftermarket adjustable versions as a result.

I also have the wheel hop problem. Has anyone come up with a fix yet. Just glad nothing grenades under hopping.

ya i also have a lot of wheel hop going on need to get this fixed.
i am thinking rear bushings

Is the problem from standstill or once you are going?

On the new Camaro ZL1 the rear axle has one solid shaft and the other is hollow in which one is twice the size of the other. Most likely the hollow. But according to Chevy after over 1K launces not one case of wheel hop. Google it.

whiteline diff bushings /thread.... again


Edit: Eliminated 100% of the wheel hop on my car.

I have SPL but haven't been able to test obvious.

I would imagine they will give you the same results. The added drivetrain vibration with the whitelines is very minimal. I actually prefer it, makes the car feel more raw.

Thxs for the input going to order the whiteline brushings.
When I order my flywheel clutch combo

Dont drive the car hard from a stop but when I give it
Alittle gas from a stop. Its hopping hard even from
First to second

think I'm one of the few here that has tried both the SPL and Whiteline. SPL bushings performance wise were great but too much damn noise. Whiteline bushings, no wheel hop but much much less NVH.

welcome to the world of 5HIT viscous diffs, get used to it. look up how they work, and you will notice why i capitalized 5HIT. If theirs one thing you want to "upgrade" to normal car status about a 370 its that above all other modifications. a clutch type 1.5 or 2 way, locking diff would make this car a completely different animal. thank nissan for wanting to save money and fitting a proper sports car with 1 step above open diff.

My car would still wheel hop with my OS Giken LSD before the new bushings, but yes I do agree the stock diff is nothing to write home about

wow the bushings made that much of a difference? you think it would be as dramatic on the nismo? the suspensions already stupid stiff as it is. so my guess is when i toss that nismo GT pro carbon under it, bye bye useless wheel hopping econocar launch, hello proper sports car. "take note nissan"

could be wrong but i always thought the wheel hop on this car came from how it was transferring its power to the ground.

The stock bushings just have a lot of slop in them. Maybe NA adding a true LSD will help however I know with FI the bushings are what did it for me. I have not had the car hop on me one time.

link to part u installed?

Reviving this old thread because I am really pissed off after the track..keeps popping put of first gear because I hop so badly then one run I held it in first and then my clutch went dead fish....

Lower the rear tire pressure and be more aggressive when applying the gas as the rear tires get traction from the launch (and the rear starts to squat).

I dropped the pressure to 25 in the rear and every time I launched it hopped really bsd

Perhaps coilovers will help a little? Or maybe I wasn't launching high enough/too high?

I can do burnouts no problem but it hops when I floor it in 1st and pops out of gear..

not on my Z, but on my dd that runs continental DWS it hops when i do a fast launch. i think it has more to do with the trueness of the tires.

ok, b15 is going to tell me "fast launches" are impossible with my dd.
here is a pre- :gtfo2: for ya, b15. :mad:




:rofl2:

No -- I do not. However, I have setup my suspension correctly. I also obey all posted speed laws as well as drive in a prudent fashion.

I'd only get wheelhop at the track if I didn't launch it just right. If I got on the gas too late after the rears started to grip, I'd usually get some wheel hop.

I got around that by just hitting the gas hard/fast as soon as I let the clutch out and the rear starts to squat.

It all happens in a split second so timing and practice is key.

I think it's the tires I'm running
