Bunny Hop when Accelerating

[Kazumz]

Hi all,

I do a lot of green light pulls, like a boy racer

I notice a lot of the time that the car bunny hops for grip while going in to second, but today I had a big one that I literally felt though the entire steering column (I could see it move too)...

What sort of thing does this affect and what symptoms of wear should I look out for?

clutch? or the traction control having a melt down?

It's done it since I've had it at 12k miles. Certainly feels like a traction issue, but even with semi-slicks it does the same. The whole car shakes.

Just sounds like wheel spin to me

think the description is "axle tramp" "axle hop"...

might be better then dropping the clutch is to slip it slightly more to reduce the sudden transfer of torque to the road

Thing is, my car does it when going from 1st to 2nd, not from the get go, I try not to rev is below 3k because of the flat spot.

Does this damage the chassis at all? I don't really mind if I need to replace top mounts or springs because I'm fancying an upgrade somewhere along the line.

It'll wear everything out!

 

[jamesgw200]

the front wheels easily spin 1st to 2nd. if done harshly enough it will cause the car to stutter until it regains grip.

Yeah I agree it just sound like wheel spin. It just the fronts fighting for grip and feels like it's bouncing. Not so noticeable in the wet as the wheel spins more easily/less traction, but in the dry it'll bounce.

 

[Foxspeed]

doesn't do the suspension bushes damper or springs much good doing that or engine mounts either

Sounds like a bit of mechanical sympathy is in order here Lewis

 

[Kazumz]

As long as it doesn't damage the chassis I'm not too worried.

Thanks all.

isn't this just 'kangarooing' that happens to a lot of 200s when pulling off? not wheel spin

Nah, it's not a back forwards motion it's a front wheel judder.

Just don't set off fast at the green light :lol:
