How much will new struts reduce my wheel hop when I get on it? I try and accelerate and really cant to its full potential becasue the whole front end of my car vibrates like shit and wont stop hopping so I have ot let off....anything ELSE to do in adition to stuts or will sturts alone do just fine?

Bushings and Motorsmounts... urethane.

Also, tire pressure and tire brand / model.

Biggest part.

Mayne Event · 12-15-2005, 06:29 PM

well, the pressure is fine I check it about once every two weeks and it stays steady at 25psi. They are almost brand new tires, very little tread wear but they are this new brand called Fuzion. They grip excellent however the wheel hop is a killer. Alot like this>>

Thats me in my driver seat...cept im not laughing...and im not purple..and I have hair and a nose....

Well, Fuzion (I think good year makes them) are I think only for "tuners" that want looks and lower prices.

If you really want to get into the nitty gritty, an R-compound tire and / or drag radials would be the best.

What tire size do you currently have?

Mayne Event · 12-15-2005, 06:58 PM

I have some 225/45/18. Yea the Fuzion is a cheap tire. I bought it as a package so I dident have much of a choice, I did want some Yokohama's or some Pirelli. Aside from the tires tho would the struts do a good gob of keeping the tires ON the groud?

Hey PS...if your over modding your camry it would be REALLY kool if u decided to part some it out..u know like..let me have the CF hood for a good price...n stuff.....really tho how much u sellin it for?

EDIT: oh and your trunk and the D2's

yeah those fuzions have a pretty tough sidewall and so do pirrelli tires.

I would suggest some grippy tires like the Falken Azenis sports. Those are pretty grippy.

Struts... well, they can do some what of a job, the only ones out there for our cars are the Tokico (inserts) and KYB GR-2's. I had the KYB's are those are JUNK... just an aftermarket replacement. Suspension, when it comes to wheel hop, isn't the main factor. I think bushings and motormounts are more important than dampening.

Just play with air pressure and get grippier ties.

I doubt, i'll be parting out my car. That's a last resort.

Stiffer poly mounts will help, but will not solve wheel hop from excessive power. Toyota designed the front suspension to have no wheel hop & it has none in most conditions.
Most wheel hop is inherently caused by the suspension geometry rocking backwards against the rotational force. (Remember newton's third law. The suspension is fighting the opposite force of torque through the drivetrain & amounts of weight transfer - not large amounts less you really start pushing a few hundred horsepower past stock levels.)

To solve wheel hop, the best way is to eliminate the backwards travel of the suspension.

The LARGEST single improvement you can make would be fabbing a Jbar/traction bar to hold the control arms still & eleminate the backwards travel causing most of the wheel-hop. (The most common way ties the control arms together to a stiff bar using a trailing arm. The bar mounts to the two front tow hooks, or front crossmember itself.)
When loaded correctly with a traction bar the wheels will spin just a 'lil bit - then grab. Instead of spinning / hopping.
Common home-made bars run about $80-120 to make.

It sounds like a motor mount issue. Have someone sit in your car in drive and keep foot on brake, pop hood and have them hit gas, I think you'll see your engine shifting around the engine bay. Jon.

25psi!!! WOAH, All the tyres here asks for 32-40!

Dave's · 12-16-2005, 02:18 AM

There's a huge issue about going by the auto builder's pressure recommendtion or the tire specs. Supposedly, you're to go by the auto specs. This came about, if memory serves, mostly due to the Ford Explorer blowing Bridgestone tires out and then rolling. I personally split the difference depending on tire wear. (Car says 25 and tire 32, then I run about 28)

Phat Devil · 12-16-2005, 07:12 AM

lol wow, coz unless you have crap tyres, they can usually go 40psi at least.

oh but this is for normal tyres and not snow tires and stuff. But at a psi of 25 you tyre wear will be fast! The tyres get hotter quicker too. The edges of the tyres will wear out quicker than the middle of the tyre.

I run my tyres at 40psi and travelled 200km/hr before and nothing happened *shrugs*

And also ford explorers are 4wds, car tyres and 4wd tyres are made for different purposes

check your strut mounts too

***zoni*** · 12-16-2005, 10:35 AM

the tire only says MAX pressure..... when you are eating food, do you fill yourself up to the neck with food? that would prolly be painful until you let some out, wouldnt it.

ghettosled · 12-16-2005, 11:16 AM

i thought wheel hop was a result of poor suspension geometry causing the suspension to twist during hard acceleration (just like ayzheninvasion said). i just solved that problem on my camaro a couple of months ago. i would think you should look into your suspension bushings and possibly putting in additional supports if needed.
