Wheel hop / thumping after installing new tires

[NellyGTI]

OK, ever since installing Conti EntremeContact Sport tires I've had a 'thumping' on hard launches. I'm assuming that this is an extreme wheel hop situation with the tires hooking up and slipping.

Here is a quick video which I tried to capture the sound... you can hopefully hear 3 quick thumps.

Is this wheel hop or something else?

Relavent mods:
JB4
Eibach Pro Springs
034 Dogbone

This is on a 2017 GTI Sport w/ DSG

Thanks!

Idk what that is, but if my car made that sound I would drive like a grandma for quite some time. lol

Did not seem like that hard of a launch for wheel hop.
But others might know better.
Like you I have and LSD so I have never had wheel hop.
Chirps from side to side using my summer RE-11's yes.

Have you set any vcds mods? Like the “starting vibration reduction”?

I actually tried setting it last night to ‘deactivated’ and it didn’t make a huge difference. If anything, it extended the duration of hopping.

It is certainly tied to when the tires lose traction, just would like to prevent it now (besides just being gentler with the throttle).

Get better mounts. The stock ones are very soft and 034 dog bone inserts are known to bend

I had the exact same noise when I would loose traction on hard acceleration when the roads were wet with the stock bridgestones. It scared the crap out of me every time it happened. Since I changed my tires to the michelin AS3+ I have not experienced this at all and I have put almost 10,000 miles on the new tires. My car is stock though, so maybe the Michelin’s just get that much better traction than stock causing me to not experience the noise anymore.

I've got stock everything (incl. Bridgestone stock all seasons) except for a JB4 on map 1. My wheel hop only gets that bad if it's wet outside or if I full-on floor it from a dead stop, but it doesn't look like you floored it.

I agree you might want to check on your 034 dog bone insert.

Thanks guys. I'm going to check the 034 tonight and order some new mounts. Just in time to throw on the winter wheels

Probably a loaded question, but any recommendations?

Yes - I mounted my Winter Tires (Michelin Alpin PA4's) and started having the same issue. Hehe.

I actually flashed back to the non high torque stage 1.5 file - it was too much for the winter conditions. Helped slightly.

I think the summer rubber and lighter/wider wheels spoiled me.

 

[NellyGTI]

I haven’t given into the winters yet!

Ok, here is the 034 insert, pretty sure it didn’t look like this when I installed it. I had to pry the damn thing out.

Oh wow. Is that the version 1 or 2?

They made a second version right?

Looks bent

This is version 2. Version 1 was for cars produced before 9/15 I believe.

I’m going to contact 034 and see what they say.

I knew that there were 2 versions that had different shapes, depending on the shape of the stock mount on the vehicle. As you said.

But maybe I misunderstood, I thought that they also has a second design, newer than the original ones that they produced.
