Next time can you have you girlfriend stand like 3/4 front view... Wanna see if the front wheels get off the ground after you get the wheel hop sorted out.

OP you have worlds of improvement yet with this car. Looking at your coil over thread my recommendation would be:

CS Trailing arms with ballistic joint
Trailing arm bushings
Cradle bushings
Rear upper control arm bushings
(All bushings should be the 95a harder ones)
and the heim joint CS toe rods.

(total approw 830$ with out your new found discount!)

That should get rid of A LOT of hop.

If you want more tire you can have your wheels widened to 10" (been done before) which fit with the CS trailing arms, and a 295 drag radial. 305's have been done with a 5mm wheel spacer and trailing arms along with rolled fenders, so there is that. Then there is the guy who did some major mods to his fender wells.....I think LS247 found him....not sure what tires he got to fit.

Either way, that 265 seems to hook ok. Get rid of the hop and you should cut a 1.6 60' easy.

Yup. there you go. He did all that just to get a 305 to fit in the stock offset, when it could be done with a different wheel, or running a spacer.

Nice work! By the time I get back to DC, this car is going to be in the low 10s

This makes me want to speed up getting my turbos on my 427 in the WORST way. Awesome runs!

You better square that 8.8 away first. I'm pretty sure your stock rear would finally throw up the middle finger and die

Creative Steel

UPS says the rest of the parts will be here today for Brians 8.8.

I'm thinking that's about as "squared away" as it get's. And if he doesn't drag his feet for too long there will be plenty of season left to beat on it.

These are good times to buy stock in Mickey Thompson

Weren't those cs 8.8 rears suppose to have the anti wheel hop axels? Or am I wrong

bmylez

iTrader: (3)

Yes, they are DSS axles...however, you do realize that just because something is "anti-wheelhop" it's not magic and can't compensate for the super squishy OEM bushings all over the place. We're talking about 750whp here, not some regular bolt-on car.

Well I don't know man, that's why i asked. I saw it bounce pretty harsh in those videos he posted, then on others it was non existent; I envisioned the 8.8 swap to reduce the wheel hop to a manageable level, then seeing it hop like that makes me confused.

Emphasis in bold, as to why I brought the question up.

So, if I understand this correctly, the 8.8 swap is just a piece of the puzzle to solve the wheel hop riddle?

With sticky tires.

Also, CV axels do not cause wheel hop. They can be used to help correct it, but that is a band aid, not a cure.

DarkCharisma

The 8.8 is a readily available, relatively light, inexpensive, considerably strong replacement for the V1 that is as close to drop-in as you can get. The benefit of the 8.8 is it's strength; while the axles used in the swap help with hop, it won't eliminate it; the 8.8 simply assures you that your differential will *survive* the hop.

To stop hopping you need to stop the cradle from moving under load.

If the differential wasn't made of glass there would be no reason to have an 8.8 replacement option available.

Keep in mind guys. These cradle/subframe bushings have 117k miles on them. I would never have imagined they would cause that type of violent hop, orherwise they'd already gave been replaced. but it's a learning process. You are literally looking at this cars very first passes ever. There is a lot to work on and improve. Thats why you test. This is all foreign and new to me. In no way are we dealing with a finished product. Far from it

ryridesmotox

I doubt he is going to drag his feet. He's probably ready to abuse that thing like a cheap hooker.

That statement seem intentionally confusing. Yes it will stop a lot of wheel hop but it is nearly impossible to stop it completely. Any kind of suspension. Or movement will induce hop. So the give in the bushings, the give in the suspension are huge variables. They do kind of get around it by saying the catch all about the road, tires, suspension and bushings... Etc. You put enough power through anything with a suspension and it will hop. Even a solid axle.

When the subframe moves as much as ours... Its hard to stop the hop... Can't stop the hop... Lol rhyme haha

gtistile

Car has never hopped on the steet w/ the 8.8. I was shocked when it did it at the track. Sticky pavement changes everything

LeanPocket

Ok,

That would make sense, so until the cradle bushings are addressed, the wheel hop will always be present.

That was what i was afraid of, hopping on the street.

Thanks for the feedback on that.
